Merge video with ffmpeg [closed]

Question

I have tried this command: ffmpeg -i 'concat:10.mov|11.mov' -codec copy out.mov The output file out.mov only shows whats in the first movie (10.mov).

Been googling for several hours and tried lots of things but nothing works. I want this done without re-encoding the files. Just merge with the same codec

Any ideas? Would make my life very much easier if I got this to work :)

Answer 1

Quicktime files have an index, so can't be joined using a dumb operation such as the concat protocol.

The concat demuxer is required for such formats:

#1 Create a text file.

file '10.mov'
file '11.mov'

#2 Join them

ffmpeg -f concat -i list.txt -c copy merged.mov

Answer 2

If you want to merge several video files, you can use these command.

- concat two video files.
ffmpeg -f concat -i 1.mp4 -1 2.mp4 -codec copy out.mp4

- concat multiple video files.
ffmpeg -i 1.mp4 -i 2.mp4 -i 3.mpt -vcodec copy -acodec copy out.mp4

And then you can cut a video file with ffmpeg.
ffmpeg -i 1,mp4 -vcodec copy -acodec copy -ss 00:01:20 -t 00:06:10.325 out.mp4
'-ss' : start_time
'-to' : end_time,
'-t' : duration_time;
