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 :

ffprobe : how do I get the time zone of creation date ?
29 août 2022, par Paolo BenvenutoI have a video made with a canon camera (actually a PowerShow G5Xm2), I want to extract the creation date metadata, and I found that I can see it with :

The creation date in in UTC, and it has the format "%Y-%m-%dT%H :%M :%S.%fZ". The camera has the info of the time zone, and actually it converted the local time to UTC time, so I suppose that the MP4 should hide somewhere the time zone info.


How do I see it ?
