Can you post the full, uncut terminal output?

Can you post the directory listing for this folder using `ls`?

What is the filename of the first file in the sequence?

I might be missing something here, but I don't see why you need to use
concat at all. Also the concat demuxer that you are invoking with -f
concat needs a textfile as input
(https://trac.ffmpeg.org/wiki/Concatenate) .You could just take out
the -f concat -safe 0 commands and i think you would still achieve
your goal of turning those image files into an mp4.

Best,
