How to join videos with ffmpeg?

ffmpeg has a concat command you can use. There are 2 modes demux and concat. demux is newer and better while concat is older and is support in older ffmpeg versions.

ffmpeg concatenate

For joining same codec and similar dimensions

Step 1: Create list of videos you want to join in a txt file.

file 'meow.mp4'
file 'woof.mp4'
file 'pewpew.mp4'

Step 2: Execute the following command

ffmpeg -f concat -safe 0 -i vidlist.txt -c copy output.mp4

Step 3: Enjoy the longer video.
