Convert 3G2 to AVI
About 3G2
The 3G2 format is very similar to 3GP but was designed by the 3GPP2 project for CDMA-based mobile networks (as opposed to the GSM networks that 3GP was designed for). Like 3GP, it's a legacy format optimized for low-bandwidth mobile devices and is characterized by low quality and small file sizes.
About AVI
AVI (Audio Video Interleave) is one of the oldest video formats, developed by Microsoft in 1992. As a container format, it can use a wide variety of codecs for video and audio. While it was once extremely popular, it has been largely superseded by more modern formats like MP4. It lacks modern features like native support for streaming or subtitles and can result in very large file sizes.

Frequently Asked Questions
What is the difference between 3GP and 3G2?
They are very similar, but 3G2 has some extensions and limitations compared to 3GP and was specifically designed for CDMA networks. From a user's perspective, both are legacy, low-quality mobile video formats.
Is there any reason to use 3G2 today?
No, there is no practical reason to use the 3G2 format for any new content. It is entirely obsolete.
Is AVI still a useful format?
For new video projects, AVI is not recommended. Its main use today is for compatibility with older systems or legacy content. Modern formats like MP4 offer better compression, more features, and wider compatibility.
Why do some AVI files not play audio?
This is a common issue with AVI files and is due to its reliance on codecs. The AVI file itself is just a container. If your system does not have the specific audio or video codec installed that was used to create the file, it will not be able to play correctly.
