About 3GP and AVI
3GP: 3GP was designed for mobile phones in the 2000s. It keeps files tiny, which makes it perfect for old keypad phones, feature phones and very slow connections.
AVI: AVI is Microsoft's classic video format from the Windows 95 era. It is still used by older cameras, DVD players and Windows software.
