# MLHandActionClassifier.DataSource.directoryWithVideosAndAnnotation(at:annotationFile:videoColumn:labelColumn:startTimeColumn:endTimeColumn:)

Creates a data source from a folder that contains videos and an annotation file.

## Declaration

```swift
case directoryWithVideosAndAnnotation(at: URL, annotationFile: URL, videoColumn: String, labelColumn: String, startTimeColumn: String? = nil, endTimeColumn: String? = nil)
```

## Parameters

- `at`: A URL to a folder in the file system that contains hand action videos.
- `annotationFile`: A URL to a JSON or CSV file that contains annotations for the hand action videos.
- `videoColumn`: The name of the column or key name in the annotation file that contains the video filenames.
- `labelColumn`: The name of the column or key name in the annotation file that contains the hand action label names.
- `startTimeColumn`: The name of the column or key name in the annotation file that contains the hand action’s starting-time index in the video file. Otherwise nil, if every video example starts at the beginning of the video file.
- `endTimeColumn`: The name of the column or key name in the annotation file that contains the hand action’s ending-time in the video file. Otherwise nil, if every video example ends at the end of the video file.
