[FFmpeg-user] Concatenate x10?

[Tamas Szanka]

I`m probably slow today, so where do I determine to always take
'Credit.mp4' after a video?

concat.txt file:
file 'video1.mp4'
file  'video2.mp4'
file  'video3.mp4'
file  'video4.mp4'  '
file  'video5.mp4'
file  'video6.mp4'

ffmpeg command:

ffmpeg -f concat -i concat.txt -acodec copy Temp.m4a
