With Action Labeler you can create an annotation file for further use in Create ML. Simply open the folder containing your videos and define each action with label, start and end time. After you defined all action you can export the classes as JSON file.

Supports following attributes:
– label (A name or label that describes the action)
– start (The starting-time index in the video file)
– end (The ending-time index in the video file)
– video (The file name or path of the video that contains the example action)

If you want to change the annotation file for an existing folder, simply open the folder containing the annotation file and import the settings.
