In Ubuntu 18.04 I quite often used the following command for trimming part of the video without re encoding (which means without any quality loss).

ffmpeg -ss 00:06:00 -i DSCF5984.MOV -t 00:07:00 -c copy DSCF5984_A_wszystkie.MOV

Not so much time ago I moved to Ubuntu 22.04. Still having the same video camera and still using the same format for recording, when using the command as above I'm getting quite strange error and the behavior is unexpected. In this case mov file is 40 sec file. I want to get 7 seconds fragment starting from 6 second (thus from 6 to 13 sec). Instead of this I get very short fragment from the beginning of the file. I don't even know how long as none of video players want to display its length. Probably it's 1-2 sec. Thus it's not only, I get this error, but ffmpeg doesn't work. In theory I have the newest version available for ubuntu 22.04.

Is that some kind of error? Or should I do sth different? I'm quite surprised as I didn't change my camera. So is that sth changed in ffmpeg?

It often happens when using the -ss and -t together with -c copy or -codec copy.

Modified version of your command:

ffmpeg -ss 00:06:00 -i DSCF5984.MOV -t 00:07:00 -c:a copy DSCF5984_A_wszystkie.MOV

  • I'm sorry. It doesn't help. In practice it should be "ffmpeg -ss 00:06:00 -i DSCF5984.MOV -t 00:07:00 -c:v copy -c:a copy DSCF5984_A_wszystkie.MOV" as I want to copy both audio and video. But this "version" leads to the same error and to the same incorrectly created fragment. For me it looks rather as some kind of bug. However when I put this question on stackoverflow, I didn't get any answer, just one -1 point and suggestion to close the thread. Do you perhaps have Ubuntu 22.04 and if yes, could you check on your side if it works. As I'm wondering if it's more file problem or system problem.

  • I do use Ubuntu 22.04 but I have NEVER had this bug EVER, I use FFmpeg 6.0 but I do not use the same camera

  • If you want to copy everything use -c copy anyways, note that seeking might be some what inaccurate with the video

  • It's quite strange for me that only changing ubuntu version (and ffmpge version as consequence) caused this problem. Should I then decrease ffmpeg version? How to do this in the most safe way?

  • And one thing more, I've checked this with the files I used without problems in ubuntu 18.04 and now it's not possible to trim then (in 18.04 trimming was possible). Thus something changed on ffmpeg side definitely here. for me it's bug.
