What is 3G2?

3G2 is a mobile-focused multimedia container defined by 3GPP2 for CDMA networks. Closely related to 3GP, it’s built on the ISO Base Media File Format (like MP4) and stores compressed video, audio, and metadata in a compact package. A .3g2 file typically contains H.264/AVC, H.263, or MPEG-4 Part 2 video and audio such as AAC-LC/HE-AAC, AMR-NB/WB, EVRC, QCELP, or SMV. The format was designed for low bitrates, MMS, and early phone recording, prioritizing small size over fidelity. Today, most players—including VLC, QuickTime, and many Android apps—can open 3G2, but modern workflows usually convert it to MP4 or MOV for broader compatibility and streaming. Remember: 3G2 is a container, not a codec, so quality depends on the specific streams inside.
