Transcript

Kind: captions Language: en my pleasure to introduce to you your speaker for today and his name is David Egbert he's an expert in quick time at BYU and he'll tell you all about how quick times being used at BYU to enhance the learning experience so David great thank you a be welcome i appreciate you coming today or I'm very excited to share with you some of the developments that we've been working on in synchronizing media inside a quick time as an introduction let's talk a little bit about objectives of this presentation I'd like to talk a little bit about some of the best practices and worst practices that we've encountered in using synchronized media to enhance the learning process and also we'd like to talk to you a little bit about providing you with knowledge and resources necessary for you to be able to create your own projects sometimes I know at some of these conferences we talk about all these great solutions but no actually give you the opportunity to learn how to do some of these things so I'd like to focus on that today as well here are some of the things that you learn in this presentation we'll talk a little bit about the benefits of online synchronized lectures well talk a little about the design process that the Center for instructional design does in developing some of these products we'll talk a little bit about tips and acquisition and in acquisition tips and offering and tips and deploying some of these products and lastly we'll talk a little about a little bit about how to author these materials in various different solutions inside a quick time we'll talk about quicktime pro smile using hrf tracks and lastly live stage professional of course this whole presentation is brought to you by the big blue cue a very powerful architecture we really like what what's under the hood and what's available for us when we talk to you a little bit about BYU the private university in Utah currently enrolls about 34,000 students undergraduates and admits about 7,000 new freshmen each year we also have a continuing education area that toasts about almost a half a million users are hosts about a hundred half a million enrollments in their distance education and conferences that they did they have as well and then there's the Center for instructional design and we build all the online content for both on-campus courses and also for the continuing education area the Center for instructional design also uses students extensively in the development process it's a great learning experience for them and they're very talented people so we like to leverage the students in the development process the challenge at BYU like many other universities today is that these are tough times and a BYU there's fries on building new buildings expanding our campus that way there's also a freeze on hiring and opening new positions on campus someone have to retire or quit their job to be able to open up a position for someone else there's also freeze on student enrollments we have a cap at 34,000 we can't enroll anymore because of that we're seeing increasing numbers of applicants that are turned away each year that number gets higher and higher and we're very concerned about that also freshmen are arriving much smarter and expecting much more than in the past being able to work with these students is just amazing to see how bright they are these days and they really have high expectations of college so we have a challenge the president's challenged us and challenged the whole university to think of ways that we can accommodate more people on canvas and think of ways that we can improve the student learning experience through technology of course our area takes that very seriously and hopefully today you'll be impressed with some of the things that we've found one of the initiatives that we have on campus to explore that challenge and try to find a solution that that challenges what we the hybrid distributed learning model basically what this is is that students spend half of their scheduled class time instead of in the classroom they actually learn those lectures outside of the classroom either at home on a personal computer or in a computer lab and then the other half of that a classroom experience is actually in the class where they have face-to-face collaboration with their professor and also with the rest of the classmates and discussion we try to focus on more personalized things in the classroom it's been a very interesting experience the example of using the hype that hybrid distributed learning model is a course called accounting 200 and this is the this is the solution that they have come up with it's an online lecture mode allows the professor to go through and sorry allows the students actually to go through the lesson content instead of in class I go to a computer get the contents on the computer in a very interesting experience this particular class enrolls about 1200 students annually the professor's work with the Center for instruction was designed and created about 50 hours of lectures on six CD ROMs and this is now a commercial product that other universities are leveraging took about two and a half years to develop and it took about six figures of funding to get it out the door here's the kicker software requirements this thing only runs on Windows basically there's no Mac OS support and you have to do a few things to get it work in windows XP it requires internet explorer 5 plus at the Java Virtual Machine and virtue and Windows Media Player 6.4 28 it's not compatible with nine it also leverages plastics and above and there's some documents on the CD that use acrobat reader let's look take a look quickly at some evaluations of this particular product did you the CD of course lecture format of this course to a more traditional format this is what the student said at this particular course overwhelming support for this new online experience that the students are using in the classroom take a look at some more evaluations from this particular course for this course which format you think would be would have a better would have been better in helping you more effectively and efficiently learn the core exam material instead of yet to know here the yes should save the CD format and then the no should be the in class format so again overwhelming support from the students using this class to use the CDs instead of the learning the traditional methods of lecture format in class here's another interesting question we posed for the students would you prefer the eight lectures on CD and then never meet in class again this one's a little different here we've got most of the students saying no I still want that in class experience and sort of validated our our premise that this hybrid model of having the lesson content being learned outside of class but still having that classroom experience that personalized experience with the professor in your classmates we think it's a very important aspect in using technology we don't want to lose that personal experience well let's take a look quickly at some of the student comments it was convenient and flexible student said I review difficult concepts with norm the professor on my own time very flexible the best reason why I like the CD format it because I can go back and see the lectures over again for clarification here's another student it allows you to go through at your own pace if you didn't quite understand something you can go back so this way you don't have the problem of one of the one kid in class always asking dumb questions and wasting everyone else's time amen to that no questions right okay here's some negative comments about this particular product I have quite a few problems with the technology and this was annoying to deal with and when I had to do now when I had to do the lesson another student it's not quite as easy to study off the CD as it is out of a book sometimes students are just you know the stereotypical student is so technical savvy these days there are students out there that would prefer not to use the computer from the learning experience it's another one it's hard because you cannot ask a question for clarification that's very true although in some instances we've married this with an online discussion area where the students can ask questions here's another one I was just frustrated that didn't work on my home pc with windows XP there's lots of technical issues fact technical issues seem to be the number one problem with these kinds of things here's my favorite accounting 200 is not Macintosh compatible this was a major inconvenience you know accounting is traditionally been a windows oriented study unfortunately although there are there are quite a few students now that are using our books and Mac OS 10 on campus and we don't want to leave them behind let's talk a little bit about compatibility problems now this is unbelievable I just could not believe this when windows XP was released it just drove our department crazy we had all kinds of technical problems support issues to deal with in this so now we've we have five pages of instructions on getting this thing to play back on XP you have to install real one you have to install all java java applications and you have to uninstall the Java VM and then you get to follow a 40 step process and you have to follow that process step by step we're going to have to start all over again to get this thing to run in hindsight we simply chose the wrong media architecture for this it was very obvious to us that using those various products we just did not create a durable product so we have a new project inside of CID the Center for instructional design we need to take a closer look at the requirements for synchronizing lectures on campus we want to look closely at the I we want to create an ideal solution to easily create cross-platform synchronized lectures now what every project at center for instructional design we of course have a workflow and this sort of outlines what's going on here the blue box is on the on the right are the personnel that's involved in a project and of course the processes are outlined in the green boxes so we have faculty consultants on campus that go out and find out the needs from from the faculty they are that's our whole job is to find solutions for the faculty and report some of those things back up so if a professor has a great idea like a synchronized lecture they'll go and milk route that the faculty consultant will work with the faculty to create a proposal that proposal goes to a governing body called the portfolio management team and they get to decide yay or nay they measure that against all the other priorities that we have and the money that we have available if a project gets approved it goes through a design process at the start of the design process we have a project team that's a sign we have a project manager and instructor instructional architect an art manager and also technical manager that are placed on that particular team their job is to come up with a proper design specification for each project and to also work through the production of that particular project and also conduct usability and the quality assurance and once the professor once the project's done and the professor signed off there's also an evaluation process that is absolutely critical to ensure that our materials are actually doing the things that they were designed to do so here's a spec specifications most of the specifications inside our media sync project we need this thing to be cross-platform we need full transport control over that lecture we want to be able to stop it at any point in time we need to be able to rewind those kinds of control we want an index that we can navigate to specific points in this in the lecture what of course sync slides with the audio and/or video needs to be compliant with accessibility standards that's a very important point sometimes gets neglected it also needs to have a progress indicator that's scrubbable was one critical feature request from the faculty that some faculty wants to be able to scrub and find it a specific point let's see we also need to supply our project these projects needed support standalone lessons and or whole courses it needs to be extensible about to be able to break things up the components or have one course and lastly it needs to deploy on many different delivery platforms including cd-rom DVD ROM and the web well that sounds pretty much like a job for QuickTime don't you think some of the advantage of QuickTime include cross-platform support mac and windows and you can even get interactive QuickTime running on Linux through the crossover plugin tricky part there is to get those Linux users to actually work up some money to pay for the plug-in twenty dollars sorry if I offended any Linux users out there quicktime how subtract based architecture which makes it very easy to be able to repurpose materials and put materials together quicktime has impeccable impeccable synchronicity basically must for the most part synchronizing materials in quick time is very solid occasionally we've seen some hiccups now in the input most parts very good quicktime has a long history of cd-rom and web video solutions there's all kinds of cd-rom applications out there they're leveraging QuickTime this is a big one for us we wanted to support a single plug-in not a happened Dustin this applications that all could be a point of problem we want a single plugin now let's talk a little bit about some disadvantages of quicktime the dreaded install it seems least from the administrative standpoint that seems to be a big barrier what we found is that students that's not much of a big deal for students most for the most part students don't have questions about the install they're used to installing a lot of different products on their machines there are a few barriers for getting the install process completed one is on windows especially Windows 2000 XP you need to have administrative access to the computer to make the install and sometimes when a student is using a college computer and we might not have administrative access so occasionally we need to help people that we need to help step people through the process of the install this one's actually a bigger one and that's the dreaded nag screen we get calls all the time about this you know asking us do we have to buy this upgrade sometimes it can be difficult also there are limited offering tools available there's exactly we've been searching quite a few there's just a handful of tools that really do a nice job with synchronized lectures and putting those together we wish there were more and lastly it's kinda hard to find some use cases out there they're quite there are a few that are popping up here and there now but we couldn't find a lot of use cases on using QuickTime synchronized lectures so we decided to kind of forge ahead and try to figure out what we could we could do with this architecture so here's the process that we've kind of figured out on creating synchronized lectures for ourselves we need to acquire the slides of course we go in and capture the audio of video of the professor we synchronize those slides to the audio or video we add an interface we add a caption again the accessibility issues very important to us we had an index an index that we can navigate to and then we prep those files for deployment let's talk quickly about some tips in each one of those areas of course when we receive those slides we need to convert those into something that QuickTime can support and that's very easy to do for us because QuickTime supports all kinds of standard image formats perhaps our favorite these days depending on the image format is probably PNG but depending on the case Jeff works as well so does pick and jpg if you're using X if using PowerPoint this is an important one export your PowerPoint slides to still images on the machine that it was offered off authored on and the reason for that is that when you export those slides it's leveraging the fonts right so you want to make sure if you if you were to we ran up against it's all the time and that is the PowerPoint slides were authored on a PC we take it in and put it on a mac and of course they're using all kinds of different fonts and so when we export it on the max the spacing of the fonts are very strange and all kinds of weird things are happening so that's just a tip to make sure you export here's another tip you can actually on the Macintosh if you export at picked it will render those files some of those files as vector-based and it will actually go grab the font and display it inside that still image and so for Macintosh if you export is picked and you want to make sure that they the people that are viewing your product also have that font keep things simple again we usually use pink okay here's some tips for some basic tips for capturing the audio video here's your tripod of course when you're jiggling around that camera you're wasting all kinds of pixels in the compression keep it simple and also use a lavalier or a close Mike you get a nice strong audio signal that's very important you need to prepare the lighting fact we strongly recommend that you go into the classroom or wherever you're shooting this material and scope out the lighting sometimes lighting is absolutely horrendous and I could just throw all your videos to go out the window captured the tape we've investigated capturing straight to a powerbook first or another computer sometimes there's little tiny glitches and you want to make sure that you have that source material so you can reuse that again which strongly recommend that you use tape even if you are trying to do some live capture and live compressing pre-processing and compression of course we like you squeeze cleaner and now there's compressor as well part of Final Cut Pro they're all very good tools to be able to crop your video be interlace it and compress it into the bandwidths that that you need all right I have the instructors repeat the question that's another very important issue a lot of times students will be asking questions and we just don't have the microphones out you know with the students it's just with the professor so have the professor repeat those questions so it's it's audible on the tape and this was sort of a preference we really prefer to have a formal recording session with the professor again we can get the lighting done right we can get the sound right and there's not all kinds of distractions like you know sometimes that's not very practical but if at all possible we like to bring them into this into a short small little studio and shoot them that way instead of in the classroom okay let's talk a little bit about indexing of course each slide is going to need a timestamp right so there's a few ways that you might be able to do it this is a low-tech way and actually works pretty well and that is just having a student assistant in the classroom and as the professor's moving to slide around have the student notice what time it is and mark it down on a sheet we can take that information we've have some apple scripts and some other technologies that allow us to easily synchronize those materials in high-tech includes live stage professional life States professional for now has a synchronizer and i'll show you a little bit here shortly on how to use that synchronizer to synchronize the slide materials with audio or video and they're just maybe some other tools coming out here shortly that might be available that can facilitate this as well creating the caption how do you create a caption right well what the caption the low-tech solution is to have the word processor and the your word document or word processing document up and that as you listen to the transcript you can pause it do a command to a command tab go right to their process or type it in anyway that's the low tech high tech is of course magpie can't really see your hands out there but how many of youth magpie before this is a free tool from the wgbh that runs on Java so it went on Windows and Macintosh it's an excellent tool to create captions with and again it's free what's nice about it is it allows you to control the audio and video while you're typing in the caption and then after done you just choose export and it exports to all kinds of different formats it's a very good tool so I would strongly recommend it will check it out here's the URL to that particular product there are also other tools that are available out there if you go to version tracker and type in QuickTime caption you'll find all kinds of different tools allow you to do that one other issue here one of the nice thing quicktime captions aren't only for for the deaf click on captions can also be searched i don't know if you knew this but in the pro version of quicktime there's a search feature we'd certainly like to see that available for the free version in fact we'd like all of you to go ahead and submit a request Apple to make that search feature available for the free version this can be very very useful especially in an education setting when our square student won't you know remembered something from one of the lectures but can't really find it they could pull it up and search through the caption be very useful you can also do this with wired sprites but unfortunately there are some issues they're still searching the Cashin through required sprites and hopefully those will be fixed here shortly alright creating the interface this is really simple just make sure that you know it's in a image format the QuickTime supports and I would strongly recommend that you leverage layers and I'll show you that here shortly on creating an interface all right enough we need to create a navigable interface and to do this we can lever leverage chapter tracks if you think about it quicktime has the chapter tracks allow you to jump to specific points it's really nice because it always shows you what chapter you're on right and when you need it you can click on it and navigate to the right one there's quite a few different ways you can create chapter tracks one is using Apple script and I'll show you a demo of that here shortly there's off of go live live stage Pro you can also make a visual index as well by using flash or live stays professional all right put it all together again we have many solutions here so here comes the fun part let's show you some demos here of how you can offer this stuff right inside a quicktime player pro you know thirty dollars what can you do a quick time pro so here's a demo when they're transferred to this other machine right here great here we go so here's the devil that we're going to we're going to create all right this is a professor here's the accounting 200 professor break and this particular let's go over these here we go how questions reflected here in this first problem the first one was why is it counting sometimes referred to as the language of business great so we have the video and the audio and the slides and the slide your sacred I of course the audio we also have the caption track down here if I wanted to search for something let's see they've change this used to be command F right for find now it's command R for whatever reason let's see I think Prince's accounting I think he talks about investing or something so when I search for invest I found it found investors right here and let's see if I go under edit I can choose find again and it will find that again and I can just kind of go through the whole piece and find all the different excerpts that he's talking about invest whatever is related to investing right so please click also in this particular in this particular project it has a chapter track right and as this thing is going financial accounting seeks to provide information things going user this wing Luxor Catherine track will let me know what the Olympic I'm on to management as I'm going through the project external orifice going through the lantern users of financial information would be investment sorry I'm going to turn this back up and sorry I'm not supposed to do that okay let's let's go through the process of putting this together in quicktime pro 30 bucks pretty cheap huh here we go we've got our development folder here and what I'm going to do here's the video we actually shot this and compress it and beg for and the first thing I need to do is I need to i'm going to synchronize the slides with the video ok so to do this i'm going to take my slides and again we exported the slides out from PowerPoint into excuse me gift I'm just going to I'm going to drag select all of those come down here and I'm going to pop it up inside a quicktime player all of those single images okay here we go great all right I'm going to move the video file looks over here so I can take a look at it I'm going to start with slide 1 i'm going to copy that ok and then i'm going to close it all right now over here with the video window i'm going to hold down the shift key and i'm going to hit play and while this thing is playing you notice that these little sliders here will start to move and they'll start to select a piece of the video right so here we go i'm going to hold down the shift key let's go over the questions reflected here in this first problem the first one was okay that's the first part of the slide now what I'm going to do is I'm going to add that slide that i copied straight to the video right here by using ads scaled and what that does is it actually adds that slide to the selection that I selected the piece that I selected okay now what I'm going to do is if i type command B it's going to move those selectors to the point where I just stopped right ok now I'm going to go back to slide to copy that close it out so I don't have to worry about that again and I'm going to continue by holding down the shift key and playing why is it counting sometimes referred to as the language of business well ok that's the next slide so now i can use ad scaled again and it added it I if I hit the the back arrow key once this is going back one frame and there's my slide now this is a visual right but it's still available and still totally possible to do this we found in very short projects this is actually a lot faster than some of the other things that we've found so after you go through the whole the whole piece and synchronize those slides up just using ad scaled to put all those together the next thing we need to do is we need to add an interface to the back of this to do that I'm going to hide this for just sec I'm going to go back and i created a background image now this was just created in unphotogenic ate at a region here for the trait for the transcript right and it's just a still image so I'm going to copy this to clipboard come back to my slides here this time I'm going to select the whole piece so I did the command a and then I'm going to use that scaled again and it added the interface to the whole length of the lecture right now as you can see here I don't see the video i don't see the slides and the reason for that is that when you paste a new material when you paste new material inside a quick time it always puts that to the front and we need to move some layers here so to do that you go under the movie menu down to get movie properties here we can have a listing of all the different things that have been added to this movie we have a soundtrack and these two files here actually associated to the soundtrack because it's a HD audio here's the video track and then these two video tracks here are the first two slides that we added and then this is the last video and this is actually the background image sometimes it's helpful is go ahead and select one of those images and rename it and to do that you just go to the general tab and choose change name this is the background looks great alright what we need to do with the background is we need to actually put that in back at our video and all of our slides right so to do that just come under the layer area of quicktime pro and what we need to do is is back this off and give it a high number negative numbers go closer to your eyeballs as you're seeing it and higher numbers go further back into the lair so there's we put that on layer 12 that'll be enough and you notice that the video instantly popped up if we actually go to the very front of this video now we have our slide showing as well now let's see the slides are kind of in the corner here and what we want to do is we want to put the slides in the slide area well you could actually go through every single slide and move it to the right area or we found that if you just move to the background and to do that you just move to the size property and for the background and choose and click the adjust button that will allow us to drag the background to the area where we want it to go okay here we go so we're just about there how's that now we have all our slides you could have 50 slides in there and you didn't have to move you just move the background okay so we're done with moving the background around now what we need to do we should probably take a good look at moving the video trip the video into that window and so to do that I selected the video track I'll click on the adjust again and there it is hiding behind that slide I'm just going to click on that and move it around now you got to be careful sometimes if you click one of these sides whoa look out and sometimes it wont refresh as much also you can skew it and it'll play great that way too but professor doesn't like that so okay here we go so that's about where i want that okay so let's just play it see how it's going let's go over these questions reflected here in this first problem the first one was why is it County look at that on George wisdom okay let's add a caption to this right now look look just like I addressed earlier let's see here's what the caption looks like quicktime has a text-based format for text tracks you don't actually have to author that inside a quicktime fact this is just a bbbj edit X file and there's some markup language sounds familiar like HTML or something that allows you to actually specify what's going on with this text file and so here we we specify dot size with what font we want to use a justification it's all available inside this text file so what what we like to do a lot of times if it's a pretty short piece we'll just open up our word processor and then we'll go back to quicktime player will play the language of business played a song well accounting is the language well a county is or something and we just come back and we'll type that in well accounting is you know and then we'll command tab back to their piece business because it counting seeks to provide k accounting seeks to provide and you just go and write your transcript that way usually once the transcript is done then we'll go back another time and this time around will open up our little properties window again and then in here if you go down to the time property it will show you what time that you stopped on so let's see let's let's go over these questions we let's go over these questions let's say we wanted to use that as our caption for this particular segment you'll notice that this ended at 40 34 seconds and three frames so now I can come back here and i can add that timestamp here too well let's go over these questions okay so that was 403 so I just go ahead and type that in and just keep going down the list again magpie actually does a much better job and you don't have to worry about all the time stamps and stuff so once you get that done you'll have them you'll have a movie it's ready to go I'm just going to open that up in quicktime player is our movie i'm going to choose select all and copy it close it out i'm going to go to the front of this movie and this time instead of AD scales which would scale that video clip to the length of this looming i'm going to use add instead what ad does is add just adds it as a separate track now I'm not scaling i want i want the synchronizing nature of that text track to be absolute so i don't want to use ad scale I just want to use that so now you can see that our text racks actually at the very top here we need to move that down so again I'll go under movie go down to text track this time I'll go down to size and we're going to just move that text track down to the spot that we created in our graphic for the text track great look at that all right looking good okay so now we have video we have synchronize slides we have the caption track that's already put in now let's add some interactivity let's add that chapter track now the easy way to do this that the least expensive way is actually use Apple script if you go to apple the Apple script website there's a place where you can download a set of Apple scripts just for QuickTime and when you install those and I believe with excuse me with mac OS 10.2 you also need to install the you also need to install script menu which is available right here now this is very interesting there we go okay once you install that you get the scripts and in the scripts menu here there's what we call QuickTime Player scripts and what we want to do is inside the QuickTime Player scripts as a chapter area where you can actually create and edit chapter tracks just inside of Apple script so here what we want to do first is we want to we want to create a chapter track in this particular good time moving Sophie we create that we need to pick the track that we want to synchronize this thing to and usually that's good to use unity to use the soundtrack or the video track so go in and create it you notice down here now in this in the bottom right hand corner we have a start menu that's the first entry for our chapter track now as we go through this piece let's go over these questions reflected here in this first problem the first one was ok I'm going to back that up a little bit here's another trick for you if you hold down the command key and type the left arrow it'll play this thing backwards will not refer their decision ok reflected here in this first problem I think about right about there I want my first chapter listing so what I do is go into the scripts menu go to QuickTime Player your scripts two chapters and I want to add a chapter at this current time so shows am i'm going to go ahead and name this let's see you to see thank you ok great now if we notice here we have a start menu and when I select that it go to the start and if I choose thank you it jumps exactly that spot so here's a nice low-tech way for you to be able to create a synchronized lecture right inside a quicktime player pro excuse me okay let's go back to slides please do you like that great okay let's let's talk a little bit about href tracks here's another technology you can use right side a quick time that the video is actually controlling some webpages and you can do it this way as well and so that could power but I know these guys in the back you're really nice to me I'm driving them crazy here okay so let's look at H rep tracks and how we would put this together let's show you a final product here an arrow this is what an HR rep track lecture looks like let's go over these questions reflected here in this first problem the first one was why is the counting sometimes referred to as the language of business now with this one we got that all familiar chapter track here and i can jump to a specific spot you notice when i when i go to that area and i'll hit play here in order for you to make an intelligent in uniform in I those lives which by the way mini leather guy here do we've got a brain here or dart of the video or instead of brain by your comp content of their stock investment but if you're going to try and be a you know make an intelligent informed decision you've got to get some information at least understand something about the company that you're investing in looking at what its current financial position is and so here's another way that you can use QuickTime to be able to control lectures so let's let's go through the development process of how you can put these together and to do this you need to use go lives so let's go through a project here i'm going to open up the index file really quickly and give you an idea what this looks like so first i have an index file and in here i have specific frames right I have a frame for the video I have a frame for the content and if you could also have a frame for navigation probably won't deal with that today but we'll just deal with these two these two frames here so in the in the content frame of course you've got whatever your first slide is and again this what makes this nice is that you can go into PowerPoint and say hey export my slideshow as a web page and will automatically create all those web pages for you right another nice thing about this particular solution is that web pages can be extremely lightweight much lighter than graphics so if you're just using text leveraging cascading style sheets this can be a very good solution okay so there's the content window let's look at the video window again we've got this this quicktime movie embedded into web page now some of you may not know that Goliath has a very good quicktime editor in it if I double click on this video it's opening up my QuickTime movie inside of go live and if I click on this of show timeline window button it actually opens up a timeline here's a timeline of my QuickTime movie now let's add some additional interactivity to this particular QuickTime movie I'm going to move my palette over here if you slide your objects palette over one there's a hidden quicktime palette there that have all kinds of cool things you can add to QuickTime movies we're going to add two things first we're going to add a chapter track so if we just drag that chapter track icon down there it creates a chapter track and if you select on the checker track name let me just move this inspector over a little bit it gives us a gives us the opportunity to change that that's the name of the track if you'd like and give this kind of a timestamp what's going if you select the sample which is down below this is where you can actually create through chapter tracks so we're going to start with the start okay and then you can play it down here then I copyright it was reflected here in this first problem the first one was ok so right about there is our first where we want our second chapter track so to create an additional chapter listing you can just come under here under this divided sample over here and just click in this area and now let's create a second sample here we can let's see this is Shazam right great and you can just go through your whole piece and create a chapter track going through all the different areas right okay now here's how you would create that a trip track this icon here is 48 h rep tracks and it's very similar so here let's see what so i'll have to back it up here a little bit look there we go so this is almost the exact same process first you come in here and if you were to select the h RF track it gives you the opportunity to type in a URL to wherever that slide is contained right and this is very important this target area if I were just to leave this link alone what would happen is as that QuickTime movie hit that first href listing would actually replace the movie what we need to do is have the content be replaced in that content window and so if you click this button here it kind of shows all the different frames that you have in your initial web page and we have we actually named our content window the content so we'll use that and then this is the other important parameter you need to select and that is auto load what that means is as its movies playing and when it hits that new href track it's going to autoload that that web page in the content frame so just make sure that selected now once you have the first selected you can go through again and a lot of times you find that the slides are actually synchronized with the chapter track which is synchronized with the href track so i can see visually right here in this area right here where shazam start i can just line that right up go to my divide tool divide it up and then rename that to slide too great and i can just keep going linear linear now i can just go down the linearly Wow go down the hole quicktime movie and just chop it up as I go so that's basically using an h RF track alright let's see let's go back to slides ok so we've talked a little bit quicktime player pro we've talked about HR cracks now let's talk about smile how many of you have used smile before ok a little bit handful ok smile of course is a markup language right a lot like HTML except it has a time parameter and quicktime is actually a nice player for smile and so now we're going back and i'm going to show you how to put something together and smile here's what a smile lecture looks like inside a quick time let's go okay the question was why do you smile well smile allows us to keep the content separate from the programming language that's behind it allows us to easily repurpose things because smile is a text-based format so we've got databases that can render our smile files on the fly really easily just allows us since it's text-based to really easily edit what's going on and you can see in this particular example that we have some additional functionality and that is we have this text based navigation right sitting right on the screen sometimes students like to see that kind of see what's going on what they can anticipate a little bit so you notice also that we still have our chapter track here which is something that's totally supported inside of smile let me show you what the back end of this thing looks like okay oh I just have to prove you that I can actually click through some of these and okay great so let's open this up and I can kind of show you what's going on the back end it's this presentation smile file here okay so there's different components inside a smile file that you'll need to be aware of the first part here at the very top is smile specific and and QuickTime specific parameters when you open this up for example I've set autoplay the true and I said yeah I want a time slider at the very bottom and immediate expand she ation means that everything is downloaded at once and then I also have checker track listings here and there's different modes of putting it the trackers anyway after that we have the header section just like a web page right and in the header section we have metadata that allows us to name the title of the movie so when you open this thing up it actually displays that name we can put author and all kinds of different annotations in here as well in the layout area this is the area that we get to specify what content gets displayed in what area of our lecture and so you'll notice here that we've got an area for the backdrop which includes the whole dimension of the movie we've got a region just for the video goes in the top left-hand corner we've got a region for the slides of course and we have a region for the transcript now the navigation that text navigation that you saw is a little bit more tricky inside of QuickTime what we ended up having to do is go ahead and specify a region for every single line and the reason why we had to do that is that you want each line to have an anchor tag or some way to click on it and do something right and so we had to break up unfortunately the text there fortunately it is taxed and it's pretty easy just to go ahead and add copy and paste and put those down in or use a database and extrapolate that these materials together so also there's a little tiny dot that tells us you know what topic that we're on and so again we had to break that up into separate portions finally we get the body of this is the content of what you're seeing on the screen and you'll notice here that we have the image source which is the background and it's actually associated to the region that's called backdrop and so this is where you get to take the content and tell us what region you want to put it in right and this part tag here means that to anything inside these tags is going to be parallel or meaning that it's all going to play together at the same time you notice down here after we put in the background and the video and the transcript which also be playing at the same time we have a sequence tag and what that sequence tag means is that we're actually going to start playing these things in sequence we're going to add a timestamp to it and that's where the slides are displaying at those particular times right in fact after that we have another parallel tag and we're actually showing the slides and that little pointer at the same time on the window so basically that's a smile file down here is our navigation and here's the actually using QuickTime text you notice here the QuickTime text markup language that we're using to embed that in there so it just reads the QuickTime text unfortunately smile is a standard of course right and there's different players out there that can play smile files the problem is that each smile player leverages different video and audio formats so it's very difficult to create something that's complying with all the different products and this is case in point that the text here is QuickTime specific text unfortunately so let me just show you that one more time and show you the functionality of that so again here's the metadata that's showing the title of the window we've got we can navigate through the different areas here and we can also use the chapter track the one cuz why is it counting sometimes referred to as the language of business into one solid piece actually quite a nice way to use the lectures okay let's see let's go back to slides quickly that particular smile file was created in be beheaded I've actually found that go live does a pretty good job of once you've created the initial framework to bring it in to go live and it'll mark up the text with colors that makes a little bit easier to deal with some of the things there we're actually investigating in using some web applications to create some of these things marrying being able to offer some things to the web pull it up grab timestamps throw it in a database and then output the whole final product just from a web database not quite there yet wouldn't be able to show you that today but the possibility is totally there all right let's move on now we're getting to some things a little bit more exciting let's take a look at live stage professional how many of you have have had the opportunity to take a look at live stage okay so good we've got quite a few here that's good live stage is an authoring tool specifically focusing on leveraging the interactive nature of QuickTime there's all kinds of really cool ap is on the back end of QuickTime allow for interactivity and so live stage will allow you to create a synchronized lecture with all kinds of enhancements that we have been able to do before it so without further ado here's the here's an example of a synchronized lecture done inside of live stage again very similar to what you've seen before except that this time around we have mouse over on our navigation index and we also have the cursors changing to a hand which is sometimes makes a lot of sense to have helped the students out knowing that hey this is really a button so again if we just start this off financial accounting seeks to provide information to the last question was what is jee AAP or gap well gap is generally accepted accounting great you get the idea how many of you have used the synchronizer inside of live stage we've got crickets no we got two or three here great well live stage 4 has this new feature called a lot of the synchronizer it allows you to synchronize these materials right in style right inside of live stage let me show you how to do that really quickly here all right to do that we need to create I've kind of got a shell here I've already got my video and I've got my you can see all the tracks are listed I've got video I've got a sprite track which is the sprite that's displaying exactly what topic that you're on and that gets changed through time I've also got the navigation right in this area that's a sprite track of course and those are using separate images to swap in and out as you use the mouse over I've got my text caption and soundtrack and here's my here's my soundtrack what I first need to do is go ahead and I need to create a new pitcher track so here's my picture track and i'm going to call this slide great i'm going to leave that out there okay now if I go down and I select the sound portion you'll need to use the sound when you're synchronizing this stuff if you just select video it's not going to select anything oh let me back up one last thing before I do that I'm going to select the sprite track and remove that I'm going to move my slide over to this area here and I'll just reach I'm just changing the dimension so it matches my slides there we go great so now if I select the soundtrack I come up under the movie menu and go down to media synchronizer pulls up this window it already has the soundtrack that I had selected and right now the sink source is set the background what I want to do is set that to slide now if I go over to my library in my local library I have a folder full of slides if I grab all those slides bring down just drag them into that window oh sorry one last thing we need to be on edit mode i believe and we'll just drag those to the though okay one last time well let's see I must have forgotten something anyway let's try this real quickly interesting well demo gods are not with me today I know that there's a way you can add all the slides at once and then from there you get to just you can set the end point on the first one it'll automatically start the audio clip and as you go down through the whole section you'll be able to set the out point of that particular slide you just keep going down with your slides as you're listening to the content makes it much easier to put these materials together Paul apologize for that ok let's just continue on with slides ok let's talk a little bit about deployment options of course cd-rom and DV Rama our number one choice right now seems like a lot of students still don't have broadband at home if you can believe it so cd-rom seems to be our best solution so far also this of course progressives web download just throw these video synchronized video clips on the on a web server and students can grab them from there also there's real time streaming we can actually put the video on audio on a real time streaming server and deployed these lectures that way as well so let's talk a little bit about some tips for cd-rom and DVD ROM development there's actually a couple different ways that you can put these materials on it and on a DVD and deploy them the first one would be to actually embed all of these materials in a web format so a lot of times to avoid that that nag screen will put all these materials in our webpage on web pages and create a web interface and then burn that to our DVD or CD there's an application out there for Windows that allows allows you to actually auto launch a web page and it's called shell out that we found very to be very useful it's free and here's the URL that you can grab it from but this allows you to do is on Windows it'll automatically launch your initial read page so the students don't have to go searching around on their hard drive trying to find this thing it's a very good product that we've found to be very useful of course when you're building web page you want to build in some kind of quick time checking mechanism to make sure that they might make sure that the end user has the right version of quicktime and there's various solutions out there if you're using live stage this is a very good tutorial on using QuickTime checking routines for the web and also for all sofa quicktime player you can also deploy your materials just through quicktime player itself in fact live stage for now has a deployment tool that you can just select from the file menu thing export this to cd-rom and it creates it uses this kickstart program to actually automatically check to see if the if QuickTime is installed on the clients machine and it's not a launch the QuickTime installer that you've license from QuickTime and put on the CD it's quite it flicks that up and really like that and there's some custom solutions to we've been investigating runtime revolution which is an excellent product that could do the very same thing and other products are available for director type applications as well so let's talk a little bit about web development a lot of professors really prefer this method because it's so flexible right they can easily submit changes the students can download these lectures and burn them PD if they wish that takes that cost of creating those cds away from away from the professor and for students it's not a big deal right it's possible to prevent it's also possible to prevent downloading some professors are very concerned about students ripping off their materials and not let them to use them inside a live stage of course there's the technology there that allow you to prevent downloading of those those QuickTime lectures online and lastly we here we have our tsp we have real-time streaming deployment it's a little bit more technical it does allow for instant access and so if you have a lecture that an hour long and you'd like the students to be able to get to the you know 45 minutes into the lecture without having to download the initial portion of that quicktime lecture real-time streaming is a good solution for you real-time streaming is a little more sensitive to bandwidth issues so it's not quite as forgiving you know if on a downloadable QuickTime movie you can the QuickTime movie will pause allow you to wait till you have more of a movie downloaded with real-time streaming you know the QuickTime movies trying to drop packets like crazy if you don't have enough and so you get a lot of a worse experience okay and of course real-time streaming isn't quite as portable because the video and audio reside on a real-time streaming server and the slide text and graphics need to reside somewhere else either on a cd-rom or a web server so it's not quite as flexible most again most professors enjoy having it as one package that they can just move to a CD or the web or on their hard drive wherever they need it so we're just about done in the spirit and Apple presentations there's one more thing and i want to show you and that's time skill modification this gets really fun the human brain can comprehend speech up to about 600 words per minute right some professors can be a little long long winded and a little bit boring not defending anyone ever okay why not speed up the presentation right this technology has been around for quite some time in fact the accounting 200 course that I talked about earlier as used product called emails that's available just for Windows student feedback has been very positive first it requires the students to focus they're not just watching the video at one speed they're watching the video at one and a half two times the speed two and a half times the speed the students love this by the way because they can just focus and get through the content so again we've had lots of positive feedback from the students and we've had some negative feedback as well and most of those are technical issues you get up to two and a half and you know audio is garbled it's really hard to understand it's hard to install things like that so let's do it in quick time let's go back to the slides back to the powerbook please okay so here we go let's see then tada in our secret folder we have we have a lecture here let's go over these questions reflect the gear in this first problem the first one was why the counting on behind your first level of that well accounting is the language of business because it comes alright let's crank it to two here we go it communicates for those who are participants whether making investiture crackers or managers they need information is accounting fraud confirme to serve to the base for any of these dishes as we came the second question was what did finish for coming as opposed to manage 30 count I can both of these categories that are coming are involved with finder provide information incision is who they buy that information to wrangle techniques provides information again all the navigation so where I didn't measure concern in essence in the fact can you get that you have to focus can you make that well it's pronounced like winter I think about making the best of the doctor kissing you you find okay now what you can buy the stocks of a lot of different companies even if you're focusing on being a little strange ignored add to one that's because technology business but there's a lot of businesses they're great alright so we've got all kinds of interesting feedback on that well thank you thank you very much Texas slides please what a great greatness of technology on students really really like the speeding up the lectures it could save them all kinds of time and it really requires them to focus on the material what's interesting about this is that the test scores first the test scores haven't changed at all throughout measuring from when they did traditional test and traditional lectures it moved it to the CD the test course didn't change and now they're using this this new method and the test scores still haven't changed what has changes the time the professor needs to spend in class and the time the student spends learning the materials so it's been a really fascinating experience so to wrap up like we just have a quick summary here quick time is definitely a viable solution for synchronized lectures and it doesn't have to cost you a million dollars or whatever it could be very simple it can be a very easy solution for you there are many different ways of course to create them and we've outlined some of those here we do need more applications to make this a lot easier so if you're a developer think about creating some products for education this could be one that could be a killer product I guess here's some additional program of sessions that are available I just only recommend checking out the advanced interactivity and QuickTime Michael shafts going to be doing that I'm sure it'll be just a killer session and all kinds of other interesting sessions on using QuickTime and let's see here we go oh let me back up one I got this quicktime alternative programming environments is going to talk a little bit more about runtime revolution some other products they're out there that you can incorporate to make cd-rom and other interesting things i highly recommend that one as well so here's some contact information if you have any questions about this there's my email address feel free to contact me I'd be happy to share and then also Guillermo Ortiz see in the audience he might be here as well to answer some of the technical questions on the Apple side and here's some more general information of where you can find some of these things if you check out the also the little quicktime page they're not Judy and Robert are in the audience but they have an excellent page on updated information on quicktime I'll send them a URL where you can check out some of this stuff online and Oh more don't miss some of these other interesting things are going on of course check out the content development lab and some of the lab hours
