3GP vs MP4

3GP and MP4 are related ISO-based media container formats, but target uses and playback support differ. The codecs inside the container matter as much as the extension.

Which format should you choose?

Keep existing 3GP files when playback or archiving requires them; for new delivery, test an MP4 configuration on target devices and services.
