3G2 at a glance
3G2
Convert to 3G2 when preserving compatibility with legacy CDMA handset recordings, telecom media archives, or workflows that explicitly expect 3GPP2-style mobile video.
It is useful for migration and recovery of old phone clips.
For current playback and sharing, MP4 is almost always the better destination.
MPEG-2 at a glance
MPEG-2
Convert to MPEG-2 when the target environment is DVD authoring, broadcast playout, set-top compatibility, or archive migration from systems built around classic MPEG transport and program-stream workflows.
It remains useful anywhere older professional or consumer playback chains still explicitly expect MPEG-2 video.

FAQs
Why convert 3G2 to MPEG-2?
Convert to MPEG-2 when the target environment is DVD authoring, broadcast playout, set-top compatibility, or archive migration from systems built around classic MPEG transport and program-stream workflows.
It remains useful anywhere older professional or consumer playback chains still explicitly expect MPEG-2 video.
What changes when converting 3G2 to MPEG-2?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to MPEG-2 adds streaming delivery.
What should I review after converting 3G2 to MPEG-2?
Check the exported file for Compression efficiency is roughly half that of H.264 at equivalent quality.; Higher bitrate requirements make it impractical for modern bandwidth-constrained delivery.; Patent licensing historically required MPEG LA pool payments, though most patents have now expired..
