I didn't use anything that was not obviously neeeded. What you say about previous frames was also my guess, but that doesn't seem a reasonable behaviour to me.

If ffmpeg needs more information, it should take it. That's what the logic in the parameters say. Instead of that it forces me to include some seconds that I don't want in the clip or blackening the video, both of them useless results.
- Wowfunhappy 4y agoWell that's why I thought you must have specified `-codec copy`. If you force ffmpeg to not re-encode the video, and also cut the video, it will perform that impossible action as best it can. But I legitimately don't know why that would happen otherwise. Usually it defaults to re-encoding when I use it.
- narag 4y agoIt's been a couple of years at least, so it isn't fresh. I don't remember anything about dealing with codecs. Anyway, it seems from all the links that using some re-encoding option will fix it. Thanks again!
