I have a logo which I am trying to animate; basically I want to start tight on a small portion of it, scanning across its surface and then pull back to reveal it in its entirety, all while maintaining smooth, natural motion. I am currently just keyframing the anchor point and the scale. However, there are no bezier handles in the spatial graph editor for the keyframes of the anchor point. This, I discovered, is because properties with mulitple linked dimensions do not allow you to modify the beziers (per this forum [ http://forums.creativecow.net/thread/202/883236 ]).
So I went to seperate the dimensions, but the button was grayed out. Is there anything I can do, or am doing wrong?
Separate dimensions are not available for anchor point. The other option would be to add two (or 3 for a 3D layer) expression sliders and tie each to an axis with a simple expression like this:
x = effect("Slider x")("Slider"); y = effect("Slider y")("Slider"); [x, y]
I simply renamed the sliders Slider x and Slider y and applied them to the layer. Then animate the slider values.
I usually find the easiest way to do what you are trying to do is to make the layer 3D, add a camera, and animate the camera position. The movements are easier to make look 'natural'.
Thank you Rick; I ended up backtracking and using using a camera animation; it was much smoother and easier to do as well.
