Thank you to Olivier in Yak for info.
Swedes “Syndicate” who tinker on something pretty crazy around shooting through the SLR next generation and especially the Canon just released a software only runs on Windaube7 (yes I am sectarian !). This software via a post-processing to recover the captured stream via HDMI (and 1620×910). The idea is to have a better chroma as uncompressed or almost. They speak of a capture via the Mini Matrox MXO2 which is an excellent capture system has an unbeatable price and works very well with a MacBook Pro.
I think we can also play with a Kipro home AJA, recorders at Convergent Desing type NANO Flash or Flash XDR are also welcome but they do not offer the 10bits 2 other. As a reminder the advantage of Kipro or capture systems in Convergent Design is that they are autonomous and do not require computer, they recorded on their own support. The Kipro ProRes or ProRes HQ in hard disk or SxS, the Nano Flash and his older brother up to 260mb Mpeg2 HD iFrame.
Any capture system that generates smaller file “unfortunately” can be used for compressed,H.264 compression engine of Canon's far from the worst system, might be better to go play in the big league. As a reminder the chroma is sampled in 4.2.0 this compression system which is not great.
I could not test this feature, but it is clear that I will do so as soon as possible and it gives me ideas for lab experiment should be. I imagine a compositing of the luminance after the H264 from the CompactFlash card and chrominance after the capture HDMI. it can be fun … test. By then the HDMI will be disengaged and not worth may not bother to take the lead but good idea is to dig.
More information in English on their site here : http://www.syndicate.se/Default.aspx?Id=299
One can also note on their site for an assembly with relief 2 boxes 7D, different set of fixtures for PL mounts and other BNC-R. In short in any case a source of information and interesting hacks.
