About QuickTime (MOV)
MOV is the QuickTime container format from Apple. MP4 was based on it, so the two share the same structure, but MOV is also used for editing codecs such as Apple ProRes.
iPhones and many cameras record MOV, and editors such as Final Cut Pro export it.
Outside Apple software, MOV files that use ProRes or other professional codecs often do not play without extra software.

Why won't my MOV file play on Windows or Android? QuickTime containers often carry Apple-specific codecs such as ProRes, so converting to MP4 with H.264 makes the video play everywhere.
About Opus
Opus is an open, royalty-free lossy audio codec standardised by the IETF in 2012 (RFC 6716). It handles both speech and music well, from very low to high bitrates.
Voice and video calls, WhatsApp voice messages, WebRTC, and the audio track of WebM videos.
Opus always decodes at 48 kHz, and some older players and devices do not support it.
Why convert voice recordings to Opus? It stays clear at very low bitrates, so calls and dictation shrink dramatically without becoming hard to understand.
What changes when you convert MOV to Opus
- The soundtrack of the MOV is re-encoded as Opus at the default settings, so it is close to the original but not bit-identical.
