I'm using FCP 7.0 and would like to make some changes to the white balance using Color Corrector. After clicking on auto white balance button or even making any adjustments in any of the 3 way color wheels, nothing happens. I have imported a clip using the standard XDCAM EX ...... but it remains impervious to any color changes I try to make. What am I missing here?

OK. Now I see something. I was expecting more significant changes after adjusting... as you were.

Hold the apple key down as make your changes, you will see far more dramatic changes.

Good trick. Thanks Liam.
