I quite often experience a brownish color cast when shooting indoors, although it isn't always there. The following clip (20 seconds long) illustrates the situation (http://vimeo.com/7128305). The clip is made up of two scenes that were shot separately. The first half of the clip has normal lighting, but the second half has the described color cast. The two shots were made just minutes apart. Power on the camera may have been switched off and on again in between. Also, I don't remember what the camera settings were in this case, but I'm sure they were the same.

Is anyone else experiencing this? Any ideas/suggestions would be greatly appreciated!

Thanks,
Sigr

I have the same problem! I shot a wedding and this happened to me during the wedding reception. My tint is a deep red. I shot some footage, everything was fine. Then all of a sudden the shot went dark and everything was tinted. I sent the camera in for repair (because of missing pixels). I also had the guy check the white balance. He said all of the diagnostics were fine. He said my footage is like that because I didn't have enough light. I had an on camera light that I used for weddings with a previous camera I owned and it worked fine. But, I used it with the HD7 and I guess it wasn't bright enough. I am interested to know if anyone has a solution to this too. I have another wedding in January and I'm a little worried!
