I am trying to combine 2 or more .mp4 videos into a single video (concatenation). But I am getting timestamps errors (with ffmpeg concat demuxer protocol). The videos are very similar (same resolution, fps, etc.), so I'm not sure what is causing this. I am open to trying different tools (hopefully something that runs on linux).
Apparently they are slightly different in some way.
How can I concatenate them, without losing quality?
If you need more information please tell me what command I should run to print the required details.
Update: I am trying to concatenate 4 files. I am using the command:
ffmpeg -f concat -i list.txt -c copy full.mp4
where list.txt
is a text file with the contents:
file 1.mp4
file 2.mp4
file 3.mp4
file 4.mp4
By request I executed the same command with -report
as added as the first option. This produced a large log file (110 MB) that you can see here: http://www.filedropper.com/ffmpeg-20180606-024711.
I also ran ffprobe
on each file, and uploaded the results here:
ffprobe 1.mp4

: https://justpaste.it/6r4igffprobe 3.mp4
: https://justpaste.it/77iijffprobe 4.mp4

ffprobe file
andffprobe file2
as well as your command.
