The PTS value below: 000- 000- 1000 1001 1000 111-, is for a particular case. It will
vary for other videos. I hope that didn't confuse you.

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

No, let us not make unfounded asumption and let us think in terms of
timestamps. Anything else is a waste of time.

I would try tpad=start=5, but I'm not

Hello,
I am not confident about this info but I've always thought the timebase is
usually the reciprocal of the framerate *or smaller*. As in, the duration of a
frame can be represented accurately enough as the difference between the
timestamps, which aren't counted using seconds, but "ticks"
