Render animation turns in to yellowish

Hello,

I’m giving the renderer a try, and when I render an image it turns out ok.

Things change when I want to render an animation of that setting to .mpeg movie. The render windows shows every rendered frame ok, but when I open up the .mpeg file everything turns out yellowish.

What am I doing wrong?

Perhaps you have some composite nodes enabled?

I don’t think so, it must be something with the mpeg format because when I used Avi jpg things are rendered ok.
