Apply the ColorFX to your first clip
Select all clips you want to apply the ColorFX to
Double-click the clip with the ColorFX
----when I do that it "unselects" the clips I want to change
Choose Tools->Apply ColorFX to selected clips ------Yes I can apply it , but the screen "wiggles" a little bit and than nothing..
Are any of the clips you're trying to add Color FX to already effected in some way using Media 100? I've found I can only have one Color FX applied - rendered or not. Work-arounds involve Boris or After Effects to add "layers" of effects.
