Hi, this may seem stupid, but I can't figure out how to gradually change a color to another color gradually. The closest I get is an instant change of color in Change to Color. I am trying to turn something pure white, I changed lighting to get a pure white, but the transition isn't a smooth one using this technique, please help a noob! BTW I do know about clicking the clock for time-dependent changes, I simply can't get gradual.
You can always put a copy of the clip on top of itself. Make the bottom one normal, put the effect on the top one. Then dissolve into the top as appropriate.
Using Change to Color, try to use key frames for Hue and Saturation with both near zero from the beginning and then close to 100% where the end color is to take over.
