Embedding video directly in a page favours WebM, and MKV sources arrive from recorders and archives. The conversion re-encodes to VP9 or AV1 using hardware encoders, greying the option with an explanation on machines without them, since software encoding would be dishonestly slow to offer. Audio becomes Opus. Sizes typically land under the source at matching quality. For distribution beyond browsers, the MKV to MP4 route stays the broader answer, one card away.
Questions
Why does this need hardware encoding?
VP9 and AV1 in software run many times slower than playback; a laptop would grind for hours. Hardware does it at sensible speed, so the page requires it and says when it is absent.
What if my viewers use old browsers?
Current browsers all play WebM; genuinely old ones want the MP4 route instead. Serve both if the audience is mixed.
Are files processed locally?
Yes, encode and all, streaming to disk.
