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.

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.
