Ive used Max/MSPJitter for broadcast video, HD 10 bit output, and
would like to do the same with Quartz Composer. (or at least, the
option to do the same)
As youve noted, using a Digibeta record 10 bit YUV 4:2:2, and
outputting to other sources such as D5/HDCamSR support 4:4:4 10 bit
recording. Granted it is definitely not every day you need/want to do
this, but the option would be great. In fact, there is new hardware
for HDCamSr decks that allow 2K recording with dual link HD-SDI.
Regardless, I was more curious about some of the internals of QC, and
any limitations of it.
Pierre, thank you for pointing out the 32 bit option in the Render to
Image. It was staring me in the face, and I did not see it.
Thank you,

oh yeah and there's Redcode now as well.
Maybe you meant the live input node? but video does not equal 8 bit
always...
vade your 10 bit video can't be displayed on any consumer computer
monitor but Sony Digibeta decks record in 10 bit YUV and are
commonly used in broadcast. The most common source of > 8 bit video
data is film scanners or 3d rendering. film scanners (or a spirit
Datacine) can output 10 bit log DPX files which is unpacked to 16
bit linear and 3D is often rendered in 16 bit half float OpenEXR
format for film visual effects work.
Of course now the Red camera is starting to record in a RAW format
which is close to 10 bit log so >8 bit video is going to become more
common.
8 bit projectors and displays... I reckon only a few years away.
