I realize the setpts filter can do this, but I’d like to avoid re-encoding. This is possible in most NLE software, like Adobe Premiere or Apple Cinema Tools; is there a way to do it in ffmpeg? When I try setpts with “vcodec copy” I get the error “Filtering and streamcopy cannot be used together”.
Most NLE's eventually recode when exporting though...
As the error says, you cannot use filters and stream copy together.
So no you cannot do it.
If your file is a .mov then Cinema tools is your friend.
