I am working on a video where everything was going fine, but now my Plug-ins don't seem to be working. I had a ChromaKey plug in that was working, but now it's not, even when I delete the entire media and bring it back in, and attach the plug-in all over. I know the settings are right.

Also, I'm trying to use the Brightness and Contrast Plug-in, and IT's not working, either. I can set it almost any way, and NO visible changes on the media.

Earlier, my screen seemed REALLY bright, but I fixed that.

Does anyone have a clue as to what I'm up against? Thanks in advance for the help.
