The video still has video/audio sync errors. ffmpeg -f concat -safe 0 -i mylist.txt -c:v libx264 -crf 18 -preset superfast -c:a copy output.mp4 I resolved to re-encode them all into a standard format and then concat them. I figured (after extensive googling in a topic I am not familiar with), the encodings are not the same causing some kind of desync. I started off by trying ffmpeg -f concat -safe 0 -i mylist.txt -c copy output.mp4īut this gave a ton of Non-monotonous DTS in output stream errors. If there already is an easier method to this, I would absolutely love to hear it. Note that combined, the videos are 4.13GB.

I've gone down a bit of a rabbit hole and ended up at ffmpeg trying to combine all the files into a single giant 2 and a half hour mp4 that I can then use avidemux to burn onto a DVD. I have nearly 130 files that I want to burn onto a DVD as an end result.
