Changing bitrate for HDMI out

[AdamTheBoy]

I've got what is hopefully a good question.  The 5D Mark III is getting uncompressed HDMI out in April with a firmware update and I intend on getting the atomos ninja 2 external recorder at that time.  I'm guessing that with subsequent updates the 5D mk III may be able to have it's bitrate changed.  The ninja 2 can handle up to 10-bit 4:2:2, so I'm wondering if anyone knows whether or not it will be feasible to get a 10 bit signal out of the camera through HDMI to the recorder?  I know this is hypothetical but I think that would be a really exciting development, thanks.

i think thats the point of the update.

The update on canon's website says that in april the firmware update will make it so "When shooting video, HDMI Output makes possible the recording of high-definition uncompressed video data (YCbCr 4:2:2, 8 bit) "

So even with the update to uncompressed HDMI out the 5d mk3 will still be operating in 8bit.  I was wondering if it will be possible to increase that.

At this point we'll have to assume that 4:2:2 is the internal format used by Canon's video processing runtime on DSLRs.

And about 8 bits quantization, is it hardware dependent or is it possible to push it up to 10 ?

* nanomad thinks that the ASIC that runs video processing and encoding is using 8 bit colorspace

But I haven't really looked into it

i think its safe to assume that. dunno why they downsample the color too.
