All right. This is driving me crazy. I was able to manually keyframe my scale/position values in the other comp that I was previously talking about, but it looks like I’m going to have to use an expression for this one, and I can’t figure out how to figure out the formula. Basically, it’s the same idea as my previous comp, only the camera zooms in instead of out. Basically, if I track the layer that I want to be the “postcard,” it gets too large, because my tracking matte layer’s top value is 224.5%, and my postcard layer is parented to it. So, I know that I have to create an expression on my track matte that says “scale/*”, but I’m not sure what the value of “*” is. Here is what I can tell you. My lowest scale value on the track matte is 48.91% and my upper value is 224.5%. Obviously, I want the top value to be 100% and want the rest to keep the same ratio. If someone could help me with the formula, I would be eternally grateful. (And if you have time to say how you figured out the formula, that would help, too. I’m a firm believer in learning why, not just plugging in numbers). Thanks in advance!
