  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

XAVC 4K codec

It would appear that XAVC is just High 444 h.264 profile in an MXF container. I would have to take a look at an actual file to confirm though. Premiere Pro supports this TODAY.

http://en.wikipedia.org/wiki/H.264/MPEG-4_AVC#Profiles

This is stuff that has been built into the h.264 profiles but not utilized because....Who knows...
 
I hope this means 4K broadcast cameras are arriving next year. Everything is in place, all that was missing was a codec to record to.

12 bit.
I get only get 10 bits out of x264.

Just because one encoder doesn't support creating 12 bit doesn't mean that the format cannot support it.

The High 4:4:4 Profile can support up to 14 BPC color.

h.264 supports frame sizes up to 4096x2304. Not sure if High 4:4:4 Profile extends this.

The codec was never missing, they were just features that few supported.
