Frequently Asked Questions

Is .3gpp2 the same as .3gp?▼

Both .3gpp and .3gpp2 are related multimedia container formats for mobile phones, developed by 3GPP and 3GPP2 respectively. While they share similarities and can often be played by the same software, .3gpp2 is specifically designed for the cdma2000 family of standards used in some regions, while .3gp is for the UMTS (W-CDMA) family.

Can I edit a .3gpp2 file?▼

Editing .3gpp2 files directly can be challenging as they are optimized for mobile playback rather than editing. It's usually best to convert them to a more editing-friendly format like MP4 or MOV first using a media converter.

Technical Details
