How to adjust colour of a real playe movie

Hello,

Ive just created a movie from my wedding photos. Saved all OK and plays on Real Player. Problem is the colour. Its much too red - my Dad looks like he will explode! Can I adjust it now that Ive saved it all? Ive gone back to the actual project but cant see anything to adjust colour.

I might not be able to do it but thought I would ask as Im a bit new to all of this !!!

Thanks :o)
