3G2 in sintesi
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.
IMA ADPCM in sintesi
IMA ADPCM
Convert to IMA ADPCM when a workflow needs compact audio with very cheap decoding, such as older game engines, embedded devices, telephony-adjacent systems, or legacy multimedia runtimes.
It is a practical target where playback efficiency matters more than modern codec quality.
