I've got a video file with 1.0 FPS (i.e. one frame per second) and would like to re-encode it so that it plays ca 20x faster.
A short 1 FPS sample is here: http://s3.aws.nz/cam-1537668742.mp4
I can play it 20x faster using mplayer like this:
mplayer -speed 20 cam-1537668742.mp4
How can I save it as a video file at this speed?
I tried ffmpeg's
setpts filter, it made the playback faster but still at 1 FPS, i.e. it the picture changed only every one second even though more time has lapsed in the meantime.
Any idea? Either using
ffmpeg or some other Linux tool?
