QUICK ANSWER
Is it possible to convert M2TS to AVI?
Yes - M2TS converts to AVI.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

Use the converter above or HandBrake (free, Windows/macOS/Linux) for a straightforward conversion. The video is re-encoded rather than remuxed, so some quality loss is unavoidable and the resulting .avi is often larger than an equivalent .mp4.

Why convert M2TS to AVI?

M2TS is the Blu-ray disc container and many older editing suites, DVD authoring tools, and mid-2000s media players refuse to open it. Converting to .AVI lets you bring that footage into legacy workflows without upgrading your software. AVI has been a widely accepted fallback container since 1992 and is still recognised by hardware devices that predate modern formats.

Quality & what to watch

  • AVI does not support multiple audio tracks or embedded subtitles, so Blu-ray extras such as DTS-HD audio and PGS subtitle streams are lost in the conversion.
  • The output .avi is usually larger than an .mp4 of identical quality because the AVI container is less space-efficient.
  • If you need to keep multiple audio tracks or subtitles, convert to MKV instead of AVI.

Frequently asked questions

Will I lose quality converting M2TS to AVI?
Yes - the video is re-encoded, not remuxed, so some quality change is unavoidable. Using a high-quality preset in HandBrake (RF 18-22) keeps the result close to the original.
Can I convert 4K M2TS to AVI?
Technically yes, but most AVI players and editors cannot handle HEVC inside AVI. Re-encode to H.264 - HandBrake does this by default.
Why is my converted AVI larger than the original M2TS?
AVI is a less efficient container than MPEG-TS, and re-encoding at a high-quality bitrate adds size. MP4 produces smaller files for the same visual quality.
Is there a free way to convert M2TS to AVI on Mac?
Yes - HandBrake is free and runs on macOS, or you can use FFmpeg from the command line via Homebrew.
