About 3GP and WEBM
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.
WEBM: WebM is Google's open video format using VP8/VP9 and Opus. It is built for the web and is what screen recorders and browsers produce.
