XUL in het kort
XUL
Legacy Firefox/Mozilla application development, XUL extension migration to WebExtensions, and Mozilla platform interface documentation.
M4V in het kort
M4V
Convert to M4V when the recipient workflow is Apple-centric, especially for personal libraries, legacy iTunes compatibility, or environments where Apple video metadata and playback conventions matter.
It is useful as a practical delivery format inside that ecosystem.
For the broadest cross-platform playback, standard MP4 is usually the safer choice.
