If I am correct, the 4K will be full frame width, no crop on the sides. And that alone would be significantly better than the 1DX-ii.
As well, it is very possible they could sneak a $20 (or less) OMAP type processor in the body and get out H.26[4|5] out of a DSP that is made for producing H.26x.
except it's not the DSP, it's heat management.
canon's already stated they could not do h.264 without vent ports such as the XC10 in the 1DX Mark II - thus mjpeg which is very low processor consumption.
and it was "as easy" as you think by just adding a $20 part, they would have done it to the 1DX Mark II
again - both are on the same development schedule, expecting something significantly better than the 1DXII video spec doesn't sound plausible IMO.
I am not going to say heat dissipation is not a part of it. But, what you might be missing is the notion that yeah, an modern day intel processor can easily produce H.265 video right, but I can pretty well guarantee you that an OMAP processor, with designed in proprietary IP with its sole purpose of doing compression/decompression is going to do the same encoding with
significantly less power.
While the DIGIC processor maybe very well done, they are possibly on the ASICs end of production. Relatively low volume. And frankly we have no idea if they have purchased rights to the TI IP to allow for such efficient coding.
After giving it more thought, it is exceptionally possible the DIGICs in the 1DX-ii do not have the DSP core from a vendor like TI, where as the single DIGIC in the 5DX does. As the focus of the 5DX will likely be different than the 1DX-ii.
I guess, in summary, from what I understand, having worked with OMAP processors, and with people who were on the OMAP software development team in TI, unless Canon has one heck of a core competency we do not know about, they are licensing H.264 (or such) encoding. And that comes at a cost. The 1DX-ii might not be worth putting that in, where the 5DX might be???
We are just speculating.
Maybe this weekend I will see if there are any comprehensive x-rays of the DIGIC processors out there with analysis????
