NEW H.265 CODEC

[TequilaKez]

I've just learned that h.265 AND h.264 can support 10bit color. Pretty annoying camera dev's aren't utilising it.

Please read a little bit more.
1. Had been discussed here more than once
2. There is nothing dev's could do because they have to deal with the technology Canon implemented.

I may be wrong, but I don't think he's talking about Magic Lantern not using it. I think he's just commenting on how lame it is that camera developers such as Canon and Sony are not using 10 bit colour in their codecs. It really is a shame.

^what he said

The last time I used x265 was about 8 months ago, and the quality was to be expected given the development infancy.  Just tried again with the latest build by LigH, things have improved immensely, both speed and quality.

This! I still don't understand why none of them (Canon, Sony, Panasonic... not so sure about Panasonic, Samsung, etc) don't have a DSLR or mirrorless with 4:2:2 10bit video? I've heard that its done intentionally to not kill off camcorders and other higher end products, in which case, this roughly translates to screwing with the consumer.
