Should you convert MOV to OPUS?

Yes, when you only need the sound: a song from a music video, the audio of a lecture, or a voice recording to transcribe. The picture is left out and the soundtrack is saved as OPUS.

MOV is Apple’s video container, usually H.264 or HEVC from an iPhone; OPUS is the most efficient audio codec in common use, especially for speech. Use Opus for speech and streaming where small size matters more than compatibility.

How to convert MOV to OPUS

  1. 01

    Add your MOV

    Drop your MOV video onto the box, or click to choose it. It is read from your disk and stays there.

  2. 02

    Check the settings

    The output is already set to OPUS. Change the bitrate if you want to; the defaults suit most files.

  3. 03

    Save the OPUS

    Press convert and save the OPUS. Several files come back together as a ZIP.

What changes when MOV becomes OPUS

From AAC to Opus

MOV soundtracks are usually AAC, so saving OPUS is one more lossy step. 192 kbps suits music, 128 kbps is plenty for speech, and going above the original bitrate only makes the file bigger.

Ideal for speech

Opus sounds clear at very low bitrates, which makes it the smallest option for lectures, meetings and interviews.

Video files without sound

Screen recordings and some exported clips have no audio track at all. The file is checked as soon as you add it, and you’ll be told before converting if there’s nothing to extract.

This page is put together from our notes on each format, choosing only what is true of MOV and OPUS, so every pairing states the same facts the same way. How these pages are made.

Why it doesn’t upload

Uploading a whole video to keep only its sound wastes time and data, and hands over the footage too. The audio track is read and saved right here, and the file never leaves your device.

How to check for yourself

Worth knowing

  • About the MOV. A MOV from an iPhone is usually an ordinary H.264 or HEVC video that can move into MP4 without re-encoding; a MOV exported from an editor may be ProRes and ten times larger.
  • About the OPUS. WhatsApp voice notes exported from a phone are Opus files, sometimes named .ogg, which many players and transcription services refuse.
  • AVI, WMV, FLV and other older formats use the FFmpeg engine, a one-time 31 MB download.

Questions

Does extracting OPUS from an MOV lose quality?

The soundtrack is compressed again as OPUS. At 192 kbps the difference from the original is inaudible for nearly everyone.

Can I get the audio from only part of the video?

Yes. Set a start and end time before converting, and only that section is saved as OPUS.
