Merge mp4 files with FFMPEG
Sometimes you need to merge some MP4 video files from the command line. The leading explanation I found for how to do this spends more time trying to sell you another product but it claims is easier. But it’s not a command line tool. So here’s how to use a command line tool, ffmpeg, to merge video. It may be harder to learn, but it’s much easier to automate, which is helpful if you have a large number of video clips to merge or concatenate together.
