FFmpeg no such filter 'tpad'
29 août 2022, par Zeek AranI have a simple gif. I am not in general familiar with FFmpeg commands so I assume it's just my syntax being wrong, but what I'm using is straight from an answer here so I thought it would work.


I'm trying to add a delay on the last frame of my gif.


ffmpeg -i out.gif -vf tpad=stop_mode=clone:stop_duration=2 out2.gif



But I'm getting this when I try it :
