Since there is no public documentation for a standard tool with this exact name, it is highly likely a or a batch command utilizing a media engine like FFmpeg . Technical Breakdown of the Process
: Most scripts of this nature use the FFmpeg Concat Demuxer . This method is "lossless" because it copies the data streams without re-encoding them, provided all input files have the same resolution, frame rate, and codecs.
: If the input MP4s have different settings (e.g., one is 1080p and another is 720p), the "copy" command will fail or produce a corrupted video. In these cases, the script must re-encode the videos to a unified format. merge_allmp4_at_pe_mp4
: The script creates a text file (e.g., inputs.txt ) listing all files to be merged.
If you are looking to replicate or document this functionality, it usually follows this logic: Since there is no public documentation for a
# 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
If you'd like me to write a or a functional script for this, please let me know: : If the input MP4s have different settings (e
: The at_pe_mp4 likely defines the destination filename as pe.mp4 . Standard Implementation Example
