: Automated scripts often merge files in alphabetical order. If the files are named 1.mp4 , 2.mp4 ... 10.mp4 , some systems might sort them as 1.mp4, 10.mp4, 2.mp4 .
: The allmp4 portion suggests the script scans a directory for every file with an .mp4 extension. merge_allmp4_at_pe_mp4
: The at_pe_mp4 likely defines the destination filename as pe.mp4 . Standard Implementation Example : Automated scripts often merge files in alphabetical order

# Example for Linux/Mac for f in *.mp4; do echo "file '$f'" >> inputs.txt; done Use code with caution. Copied to clipboard : FFmpeg combines them using the list. ffmpeg -f concat -safe 0 -i inputs.txt -c copy pe.mp4 Use code with caution. Copied to clipboard Common Troubleshooting in Such Reports
: Frequent merging can occasionally lead to audio-video desync if the timestamps in the source files are inconsistent.
