Run the following command: ffmpeg -f concat -safe 0 -i inputs.txt -c copy output.mp4 .

The phrase "mergemp4" is likely a misspelling of a command or a reference to specific open-source scripts, such as Ayx03/mergemp4 on GitHub. Standard Methods for Merging All MP4 Clips

: The most efficient way to merge videos without re-encoding (which preserves quality and is very fast).

: Methodologies for video captioning often describe transforming raw MP4 inputs into sequences for model training.

: Papers like MMTrail discuss merging and splitting millions of clips to create multimodal datasets.

Create a text file (e.g., inputs.txt ) listing all files: file 'clip1.mp4' , file 'clip2.mp4' .
