How to convert MPEG4 to AVI
- Add your .MPEG4 file - drop it in the box above or click to browse.
- Convert it to .AVI in a few seconds.
- Download your new .AVI file.
What to expect
- AVI does not support AAC audio - the audio track is automatically re-encoded to MP3, causing a small additional quality loss.
- AVI files are typically larger than the source MPEG-4 at the same visual quality because Xvid and DivX compress less efficiently than H.264.
- AVI cannot carry subtitle tracks - any subtitles embedded in the
.mpeg4file will be silently dropped.
Frequently asked questions
Will converting to AVI reduce the video quality?
Yes, slightly - re-encoding always loses a small amount of quality. Use a high-quality setting in your tool of choice to keep the difference invisible.
Which video codec should I pick inside the AVI container?
Xvid is the safest choice for compatibility with old players and devices. H.264 can technically be placed inside AVI but many legacy players will not recognize it.
My editor says it needs AVI - is there a better alternative?
Check whether your editor also accepts MKV or MOV, which support H.264 without re-encoding and are better containers than AVI in every respect.
Does AVI support surround sound?
No - AVI uses MP3 audio, which is stereo only, so any 5.1 surround track in the source will be downmixed to stereo.
