thx for the -codec copy tip. I was too lazy to read through man pages of ffmpeg to figure out that omitting the codec attribute leads to actually encoding the trimmed video by default.

Do you mind if I make a copy of this only for my use? I saw BigBoy on its first run after rebuild but was unable to get any viewable video. Yours is great. BTW thanks for your tutorials; I have learned a lot from viewing them.

if you enter the code without "-codec copy" trimming process taking longer but the output video is less likely to be buggy. I encountered some bugs with "-codec copy" and deleting these, did the trick.

If you don't use "-codec copy" it is re-encoding the video which can lower the quality. That is certainly an acceptable way to do it but I wanted to focus on the lossless technique for this video.

Most of the time this works but I have this one clip that is 20:48 long and I try to copy from 0:00 to 20:30 and the resulting video is blank/black for the first 25 seconds though audio plays through it. I think I need to re-encode.
@Ryan-rn7ck2 жыл бұрын
Re-encode using the following: ffmpeg -i out.mp4 -ss 00:01:03.0000 -to 00:01:13.0000 -c:v libx264 -c:a copy out2.mp4 You will want to _not_ copy the codec otherwise, it can not on something that isn't a keyframe and cause black frames in the beginning of the video. This command will re-encode, which may or may not satisfy your use-case, but the trim will be more accurate.

I don't have ffplay, how to install that?
@jumanjiwarlord10 ай бұрын
When installing ffmpeg from Homebrew - ffplay automatically gets installed. *If you're not familiar with Homebrew, you might want to familiarize yourself with that. Once Homebrew is running, it's as easy as: "brew install ffmpeg" But, Homebrew itself as a concept takes some getting used to....
