Convert MOV to AVI online

To convert MOV to AVI, upload the MOV file, start the conversion and download the result: Converter.now writes an AVI with Xvid (MPEG-4 Part 2) video and MP3 audio. The first video and audio tracks are re-encoded; extra audio tracks and embedded subtitles are not copied. Both formats are lossy, so this adds a second round of compression; convert from the best original you have rather than an earlier export.

How MOV turns into AVI: Timed-stream transcoding

Decoding MOV recovers the picture, sound, and timing streams it carries; writing AVI means re-expressing that under a different codec and container profile. Duration commonly survives untouched even while compression, channel mapping, cadence, metadata, or auxiliary streams do not. QuickTime MOV input uses atom-based track and sample tables, including edit lists, rotation, color labels, timecode, chapters, and auxiliary media. AVI output interleaves indexed audio and video chunks in a legacy RIFF container whose subtitle, modern metadata, and variable-frame-rate behavior is limited.

Decoded from a QuickTime container written here with H.264 video and AAC audio. Encoded to an older Microsoft media container commonly paired here with Xvid video and MP3 audio.

If you want the reasoning behind this MOV to AVI route, the difference between a container and a codec explains why a familiar extension can still fail to play.

What the MOV source carries and the AVI output demands

What can fail when QuickTime Movie is interpreted

MOV support varies outside Apple and editing software, while source captions or extra tracks may not be retained.

What AVI video container cannot safely promise

AVI has limited support for modern metadata, captions, variable frame rates, and some web players.

How the AVI writer handles this route

The verified AVI profile uses Xvid video and MP3 audio for compatibility with older AVI workflows.

Checking the AVI result before you trust it

Record the MOV evidence before conversion

Scrub the timeline and verify frame size, frame rate, audio sync, color, and target-app playback.

Test the AVI file in its receiving workflow

Test seeking and audio sync in the target player, not only the opening frame.

When to actually choose MOV to AVI

Confirm the receiving player, editor, or publishing service actually names AVI's container and codecs before switching; stay with MOV if extra tracks or original encoding need to survive intact.

What changes between the MOV model and the AVI deliverable

The first video and audio tracks are re-encoded; extra audio tracks and embedded subtitles are not copied.
Both formats are lossy, so this adds a second round of compression; convert from the best original you have rather than an earlier export.
Treat MOV-specific metadata fields as optional in the AVI result until you have actually confirmed they survived.
