MPEG at a glance
MPEG
Convert to MPEG when maintaining compatibility with older playback devices, disc-related workflows, or archived video libraries that were created around classic MPEG distribution.
It is useful as a bridge format for restoring or normalizing legacy video.
For current delivery, newer containers and codecs are usually better.
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.
