How to extract video frames?

[ChocoWu]

Thanks for the great work.
When editing a new video based on NLA models, we should first extract the frames within a video and save it into a video_name/frames_xxx.jpg.
I want to know how to extract video frames and if there are any fixed frame numbers for a video.
It would be better if the authors could provide the related pre-processed code.

u can use ffmepg to do so :), there is no fixed frame numbers for a video, but make sure dont introduce very low fps or large motion. good luck
