Hi, let me explain my problem;
I have a 5000x5000 px .PNG that I want to show a bit at a time in a1920x1080 comp.
The .png layer moves left by x-amount and holds it's position, then left again, holds, then moves diagonally left and down. The movement repeats until the entire .png has been revealed a piece at a time. It's supposed to mimic the movement of the eyes scanning left-left-down and left-etc when reading a graphic novel. The 'hold' is the eyes absorbing the information within the comic frame before sweeping left.
That bit's fine. But I want to add a wiggle expression to mimic the random, slightly unsteady movements of the eyes and human body (think 'handheld' aesthetic in movies).
How do I add the wiggle when I already have positional keyframes in place?
I tried precomposing the layer and adding the wiggle to the original layer and precomp' but neither method worked.
Wiggle is additively applied to whatever the current property value is, so it doesn't matter whether there are keyframes or not. Simply apply it to the actual moving image. The rest will depend on your actual settings, but since you haven't provided them, we can't tell you what may be wrong.
Thanks for your response, perhaps the expression values aren't high enough to be noticeable? Will experiment.
Sorry if this seems like a stupid question but couldn't think of a work-around.
Yep, I just hadn't used high enough values, presumably because the actual layer is 5000px square the values need to be exponentially bigger. Thanks for your help!
