MKVIN
Matroska, seen as .mkv, is an open container with no practical limit on how many video, audio, subtitle and chapter tracks you stack inside one file. That makes it the usual home for a film kept with several language tracks and forced subtitles. Desktop players handle it well, while phones, TVs and browsers often refuse it.
WEBMOUT
WebM was built by Google for video that plays inside a web page with no plugin involved. It pairs VP8 or VP9 video with Opus or Vorbis audio, and no codec royalties attach to it, so shipping it on a site raises no licensing questions. It suits background clips, product demos and anything embedded straight into HTML.
