3GP in het kort
3GP
Convert to 3GP when preserving or processing older mobile phone footage, MMS-era videos, or device-targeted clips for constrained mobile environments.
It is a reasonable compatibility target for archival workflows involving legacy handsets.
For general-purpose delivery, MP4 is the more practical modern choice.
AMR in het kort
AMR
Convert to AMR when the target is a speech-oriented mobile or telephony workflow, such as voicemail systems, call recordings, or compatibility with older handset ecosystems.
It is useful when bandwidth and voice intelligibility matter more than music quality.
For music or general listening, AAC, Opus, or WAV are better targets.
