MP4, MOV, WebM, and other readable video files

How this tool works

Supported inputs
MOV and other readable video files, including MP4 sources you want rewritten as MP4.
What happens
Auto copies compatible tracks into MP4 when possible and re-encodes when required. Remux copies without changing the picture or sound. Transcode re-encodes to H.264 and AAC for broader playback.
Limits
Remux needs codecs that MP4 can hold. An extra track this browser cannot read, such as spatial audio, is left out while the main video and audio are kept.
