Color temperature changing during video shot (7D)

Hello!

 

Yesterday I shot some videos with my 7D and after downloading the videos to my laptop I noticed every movie starts with the correct color temperature and after a few seconds the colors seem a lot hotter.

 

Does somebody knows why this happens and how can I prevent that?

 

Here are some facts:

 

* I was using Live View so I could trigger movie recording remotely from my laptop (I was shooting alone).

 

* I recorded SEVERAL takes within a period of 4 hours, each take lasting about 2 minutes, and waiting about 1 or 2 minutes before starting recording the next take (sometimes I started immediately). I kept just the very last ones, so I don't know if this issue was happening during the first takes. Could this problem be related to camera sensor working for hours straight, even taking a break of 1 or 2 minutes between each take?

 

* Light sources remained constant during the entire recording session.

 

Below are some screenshots so you can see what I'm talking about:

 

Thanks!

No this happens in Manual mode.

Manual shooting mode, and the other creative modes, are independent of the WB setting.  But, congrats on finding a resolution.
