Hold up can someone please tell me what benefits MKV has over let's say MP4 ?
Here is a pretty good write up on it. They aren’t that different but generally I think mkv is preferred in high quality since it can handle more tracks and more codecs.
It supports more codecs and I believe can store more tracks compared to MP4. Whenever I download a high quality movie or tv show, especially if it has multiple audio tracks and subtitles to choose from, it is always packaged in .mkv
It supports more complicated subtitles and menuing, more codec support (like a LOT more) lossless support, mode audio formats.
It's like they took MP4 and added in all the stuff that you needed to replicate a BluRay, then added in lossless audio.
If you just want a movie with basic subtitles and audio, MP4 is fine. If you want to replicate newer stuff, MKV supports it.
The real hot part of this is if you have a collection of high-quality video/audio and you're streaming it to firefox, you'll natively be able to do so without transcoding.
