I'm looking for a tool for annotating gestures in a video. There are tons of tools for tracking objects in videos, but all I want to do is annotate when gestures start and end in a video, not where they are in the frame. I would want to be able to go through the video and manually indicate when a particular gesture starts and ends, and which type of gesture it was. I would want an output file that had a list of gestures in the video, and the type, onset, and offset times for each gesture.
Is there a tool out there that does something like that? Seems like either it doesn't exist, or I haven't found the magic google keyword yet. Thank you!
