Animation

Animation

Animation Create animations by changing specific adjustment attributes and effect parameters over time.

Overview

You can create animations with a Parameter Element for the attribute or parameter to animate, along with a keyframeAnimation element that has a series of keyframe elements, each of which defines a value at a point in time.

To produce a keyframe animation, specify the time points and values for each keyframe using the time and value attributes of the keyframe element. The Final Cut Pro application interpolates the values between them.

The following example performs a position and scale transform adjustment animation using keyframes:

<adjust-transform position="-10 10">
   <param name="position">
      <keyframeAnimation>
         <keyframe time="0s" value="-5 10" />
         <keyframe time="10s" value="10 20" />
      </keyframeAnimation>
   </param>
   <param name="scale">
      <keyframeAnimation>
         <keyframe time="0s" value="1 1" />
         <keyframe time="10s" value="0.75 0.75" />
      </keyframeAnimation>
   </param>
</adjust-transform>

Initially, when time is equal to 0 seconds (time=0s), the frame is moved left 5 percent and up 10 percent (“-5 10”) of the project’s height from the original location, with no change in size (“1 1”). When time is equal to 10 seconds (time=10s), the frame has moved 10 percent right and 20 percent up (“10 20”) of the project’s height from the original location, with a 25 percent (“0.75 0.75”) reduction in size from the original (“1 1”). For more information on the adjust-transform element, see Video Adjustment Elements.

Final Cut Pro determines the parameter value based on the following priority (with 1 being the highest priority):

  • The value and time attributes of the keyframe element, for a particular time
  • The value attribute of the param element
  • The respective attribute of the adjustment, if applicable

In the previous example, it doesn’t matter that the position attribute of the adjust-transform element has a value of “-10 10”, because the keyframe defined at when time is equal to 0s (time=0s) (in the keyframe element) takes priority and overrides the value to “-5 10”.
