file 'jan_2017_game_part1.m4v'
file 'jan_2017_game_part2.m4v'
file 'jan_2017_game_part3.m4v'
file 'jan_2017_game_part4.m4v'
file 'jan_2017_game_part5.m4v'
file 'jan_2017_game_part6.m4v'
file 'jan_2017_game_part7.m4v'
file 'jan_2017_game_part8.m4v'</file>
  - Then run **ffmpeg** with **-f concat -i <LISTFILE> -copy <OUTPUTFILE>** or <file>ffmpeg -f concat -i mergelist.txt -c copy output.mp4</file>
