Is there a way to use a slider to control the various attributes that make up a levels adjustment via expression? I am able to set them via scripting and have done so. However, the stopwatch that lets me create an expression is linked to the histogram as a whole, not its individual components, i.e. input black, input white, gamma, etc. Is this possible or am I barking up the wrong tree here? The goal is to control multiple levels applied to individual clips in one nice, neat location. An adjustment layer will not work for me because of layering. Also, I do not want my background to be effected by the adjustment, just a few of the pieces that make up my foreground objects.
Excellent! Thanks for the heads up. Can't believe I didn't think of this on my own. Doh!!
