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.
WMF at a glance
WMF
Convert to WMF when preserving compatibility with older Windows document workflows, embedded legacy graphics, or archive recovery tasks where that classic metafile format is still expected.
It is useful as a bridge for historical Office-era vector assets.
For contemporary vector exchange, EMF, SVG, or PDF are usually more practical.
