Can't use Lens Distortion?

[leomendes801]

Hi guys.

I tried to follow a tutorial on YouTube on how to make an RGB Warp Transtition, which is a transition where one clip "warps" to the next clip with some sort of RGB color distortion. The first (or second) part of the process though, is to add the Lens Distorion effect on an adjustment layer. And that's where I've been having some trouble.

To make the warp effect, I'd have to add 3 curvature keyframes onto the adjustment layer; one at the beginning, one in the middle, and another one at the end of the layer. But whenever I try to add multiple curvature keyframes, the curvature effect simply doesn't show up. I tried changing the values of each keyframe, but yeah, whenever there's more than one keyframe, it just doesn't work. It does work when it's just a single keyframe in the middle.

I have seen comments from other people with the same problem in the comments section of that video, and I don't think anyone fixed it.

Thanks in advance, guys.
