What changes when you convert WebM to MOV
- WebM and MOV are containers. The video and audio streams are re-encoded into codecs that MOV supports (typically H.264, HEVC, ProRes), so you get a file that plays reliably rather than a simple rename.
- The audio track is carried over to the MOV file, re-encoded if needed.
- MOV is newer or less widely supported than WebM. Check that the website, app or device where you will use the file accepts MOV.
