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.
PBM in sintesi
PBM
Convert to PBM when you need a bare-bones monochrome raster for command-line tooling, research, or low-level graphics processing.
It is useful for simple binary image exchange and intermediate processing.
