Hello,

Does the duration of the training video have to be the same as that of the prediction window? For eg: if my prediction window is 2s, do the training windows have to be also 2s in length?

Thanks for your help!

No, the videos can be any length. Longer videos will provide multiple training instances. Shorter videos will be padded.

But as an optimization you may want to try extracting key points yourself with keypointsWithAnnotations(targetFrameRate😃 and manually curating the key point data.
