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.
What is MPEG?
MPEG (.mpeg or .mpg) usually refers to the MPEG-1/2 Program Stream container plus its classic video codecs. An .mpeg file typically holds MPEG-1 or MPEG-2 video with MP2/MP3 (or sometimes AC-3) audio, multiplexed for smooth playback on computers, set-top boxes, and legacy DVDs/VCDs. The compression is lossy and block-based, great for the era of low bitrates, but less efficient than modern H.264/AVC or HEVC at the same quality. Most players—VLC, Windows apps, QuickTime, and many TVs—open MPEG natively; editors can often remux to MP4 or MKV without re-encoding if codecs are supported. Note that MPEG-2 Transport Streams use .ts or .m2ts, and MPEG-4 files usually use .mp4, not .mpeg. Converting old MPEG to MP4 (H.264/AAC) yields smaller files and broader web compatibility.
