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.
JXR at a glance
JXR
Convert to JXR when the receiving environment explicitly expects JPEG XR or when recovering historical assets from that ecosystem.
For broader distribution, TIFF, PNG, AVIF, or WebP are usually easier choices.
