When to convert MP4 to AVI
AVI can be useful for legacy players, older Windows software, archives, or tools that specifically require an .avi file. MP4 is generally a better choice for modern browser and mobile playback.

AVI output codecs
The converted AVI contains MPEG-4 Part 2 video and MP3 audio. Because AVI is only a container, confirm that the destination supports those codecs rather than assuming every AVI file will work.
File-size tradeoffs
MPEG-4 Part 2 can be less storage-efficient than the H.264 video commonly found in MP4 files. The AVI result may therefore be larger than the upload and is not intended as a compression tool.
What conversion preserves
The primary video and audio are re-encoded into the AVI output. Extra subtitle tracks, chapters, attachments, and MP4-specific metadata should not be expected to carry over.
