Hi,
Let's assume the framerate is constant. For example, I want to delay a video by
5 frames and then hstack the original video and the delayed version:
ffmpeg -i test.mp4 -vf "split[a][b];[b]setpts=PTS+5/(FR*TB)[c];[a][c]hstack" -y
out.mp4
I would try tpad=start=5, but I'm not sure what happens for the first 5
frames... If your example works I'm pretty sure it would work.
ffmpeg -i test.mp4 -vf "split[a],tpad=start=5[b];[a][b]hstack" -y out.mp4
yes, that does also work fine. For the first 5 frames it's black, or the
first frame can be cloned if "start_mode=clone" is added.
