user4975: I have dozens of video files containing scenes of movement interspersed with 5-10 second periods of nothing happening (many identical frames in a row). There's no audio track and I'd like to strip the identical frames to remove those pauses and keep only the movement.
Is there a (preferably free) tool to accomplish this?

user4975: This can be accomplished with the mpdecimate filter in the free program ffmpeg:
ffmpeg -i "in.mp4" -vf "mpdecimate" "out.mp4"
