I'm using the Colorista Free plugin for FCP 7. Here's the problem I'm getting: when playback is paused, the image in the Canvas matches the image in the Viewer and looks exactly the way I want it to. When I start playing the timeline, however, everything in the Canvas suddenly looks darker, or as if the effects of the filter are being intensified. I exported a test to make sure this wasn't just a playback issue within FCP, and the export looks dark as well.
I can't adjust my filter to compensate for this without going through an excruciating trial-and-error process, because the results that I see when I adjust the filter are not the same results that are actually being applied to the clip! Is this a settings issue, or a problem with Colorista, or something else? I've used it before on previous projects, so I just don't know what's different this time.
Canvas background is set to black. Another weird thing, the first thing I tried to do was trash the FCP preferences and reopen, which didn't seem to make a difference. But later I closed the project down and left for lunch (about an hour or so), and when I came back everything seemed to be working normally again. It's currently doing okay, though I'm not sure what I did to fix it.
