Footage from FS700+ Odyssey 7Q

Hi Dan,
Looking at the CD website, I have a question. The standard 7Q comes with 1080 12 bit 444, and the FS700 package has
1080p 10-bit YCC pulled from 4k. Does this mean we are limited to subsampled YCC 10bit 1080 with the fs700, or can the base package pull a 12bit 444 RGB signal from the camera? Looking forward to grabbing the FS700 package either way!!
 
Two more questions, any word on battery prices, and will there be a power adapter so that we can power the unit from vmount 7.2V batteries?
 
I think a lot of people are having these types of questions. I'm not familiar with YCC... but I do see that the 4k is going to be an uncompressed format , vs the RAW that the sony one has. I'm hoping CD can clarify some of this stuff before release, because if this thing works as good as all the talk I'm going to pick one up right away! as long as it isn't sold out ;-)

I'm not too familiar with it, but YCC is a color space that has luminance values in addition to the chroma values that we usually find in RGB color space. So apparently it's better because it's not based purely on color the way RGB is, it's color+luminance, so you've got more information. Of course, you can always create an RGB file from YCC if you needed/wanted to.

YCC is YCbCr which is a simple linear transform to/from RGB. It does not contain any more information than RGB. In image compression, RGB is converted to YCbCr/YCC/YUV so the luminance Y can be compressed separately from the chrominance CbCr. The chrominance can be compressed more heavily and at a lower resolution than luminance (422 = 1/2 color information, 420, 1/4 color information).
 
Most cameras capture in YUV. Most NLE's process in RGB. Conversion from one to another is, generally, a lossy process, and not simple. There are numerous round-off errors that degrade image quality. The less conversion one needs to do, one color space to the other, the better off you are.

All cameras have RGB sensors but tend to process into YUV for output because of the compression. There isn't a straight YUV -> RGB process and in fact mistakes are often made - all you have to do is try various permutations of codec and application and compare the subtle shifts in colour. I'd always thought that YUV was actually slightly more accurate at representing colour but i might be wrong?

YCC, YCbCr, and YUV all mean basically the same thing: luminance (Y) and chrominance (CC, CbCr, and UV). It's a super simple process to convert from/to YCC and RGB. 9 multiplies and 9 add/subs (matrix form). It is however a lossy process, software has bugs, and incorrect matrices are sometimes used. Ideally stay in RGB for as long as possible, then convert to YCC before compression and storage.
