MKV at a glance
MKV
Convert to MKV when you need multiple tracks, subtitle support, chaptering, or less common codec combinations in a single container.
It is ideal for archival masters, media-library organisation, multilingual releases, and technical video handoff.
For mainstream web playback and easiest consumer sharing, MP4 is usually simpler.
3GPP Mobile Video at a glance
3GPP Mobile Video
Convert to 3GPP mobile video when preserving early phone footage, reopening MMS-era media libraries, or targeting an older handset workflow that still expects 3GP-style packaging.
In most current environments it is better treated as a migration source than as a preferred final format.
