No worries, I get what you mean about not knowing skill level. I’ve got years of experience and this one has me feeling like an idiot.

No blend functions, no effects, no resizing or anything. Comp size solid with mask at a reasonable number. 8, 16 or 32 bit….same thing.

Here’s the crazy thing, doing some messing around, it literally only happens if the solid is set to pure black. If I put even the smallest amount of lightness in it (so it’s basically 99.9% black), it fixes it and goes to the normal way you’d expect a feather to work.

Any idea what would be causing that??

I get that, but if you look, the mask feathers out then stops hard for no reason. I’ve done it on various size mask and it doesn’t matter.

In this case, it’s a 1920×1080 image and solid. I put this mask on it and gave it a 100 feather. No reason at all it should look like this, never had this type of problem in previous versions of after effects.

Unfortunetly, I’ve tried the pulldown options, and all of them look the same once imported. I do have a lateral motion (it’s a ball that rolls across the screen), so if that’s the case, does it look like I’m screwed? Will I have to come up with some other animation as the first poster suggested?
