The raw looks too warm. But I didn't like the halo around the fire of the candle of the H.264 at 200%. Interesting stuff and I can't wait for ML to get to the 6D, if it ever does.
Well guess what, it's RAW and a simple adjustment in white balance and your gold! (or silver, for the cooler color??)
And I recall some early attempts/tests proving the 6D is capable as well, but alas, extreme card speeds are required and both the current limitations of SD card speeds and the major issue, the uber slow transfer from buffer to card in the 6D kills it. You might be able to run lower res sequences around 720P but still doesn't look great. Now the 50D looks to be capable of RAW video as well, and that camera has fast transfer speeds so with the fastes SD cards (95mb/s) one can achieve desirable results.
