As other has mentioned when recording video there is a colorshift as soon as you press the rec-button on G6. When comparing a photo jpeg to the h264-file the colors differ a lot, its like magenta is replaced with yellow, red tones towards magenta look orange.
When trying to match in Final Cut by adding magenta I got a magenta cast in the rest of the image..
In 5d2RGB I tried different settings to transcode the h264-file, found a fix!, When using "ITU-R BT.601" in Decoding Matrix magenta gets back and the image looks almost exactly like the still-jpeg (and correct).
Attatched images is exported frames from Premiere Pro CS6, they look the same i Final Cut 7. I was about to give up on the G6, the skin colors looked so weird.
