Ok I shouldn't use the word nobody, I admonished someone for using that word a few days ago, but it's very rare, especially outside high end production houses.

Even 12G sdi is compressed - we consider 4:2:2 and 10bit uncompressed, but 4:4:4 is less compressed than 4:2:2. Once you go into interlace or stupid things like 24p you're throwing away tons of data.

2022-6 seems to be the transmission method of choice so far, 2110 may well take over, but there are significant compatibility issues.

Personally I'd prefer everything originated as 4:4:4 10 bit 150fps (no drop frames), resolution I'm less concerned with.

I work in news though, broadcast quality is what we broadcast. 5mbit h264 PPP with a vbv of 200k is fine for a talking head internationally. 5 times that is plenty for an actual broadcast program with astons and stuff.
