I may misunderstand but FFmpeg treats all video as frame-based. > Concretely: > * Could I (easily) extract every nth frame from a video (in order to > dump the result as JPEGs)? See the select or the fps filter or use a low output frame rate (which forces frame drops). > * Could I subtract each frame from its predecessor (in order to detect > minimal motion)? I suspect there is a filter, maybe blend?
