how to go front or back the video 1-3 frames only i want to sync two different video
Just grab it on the timeline and move left/right.
@xenofoneftychidis What you are looking for is a nudge feature to bump the one of the clips a frame at a time, yes? I am not sure if this is a thing yet, but @FilmSensei might have better knowledge...okay, no mights will have better knowledge. If not in HF yet, would be a good request in that forum unless it's already there. Will check.
Yes, there is a request already here:
Give it Vote Up and maybe drop a comment to bring it to the top of the forum list so it gets some love from the Devs.
