Final Cut: Color Corrector causes color inversion and posterization on Freeze Frames

In Final Cut Pro, using the Color Corrector filter over the Cross Dissolve transition when applied to Freeze Frames sometimes causes a color inversion and posterization effect.

I’ve found two ways around this:
1. Use the 3-way color corrector instead, or any of the other color adjustment filters.
2. Apply the Color Corrector filter to the Freeze Frame in a new sequence. Then use that as a nested clip in the main sequence, and apply the Cross Dissolve to that nested clip.

Thanks much to “Sureal” for the second solution!
