I poked around. but didn't see much, so I tried to use the generator to make a growing little circle and it worked! Well, sat least good enough for my purposes.
The PROBLEM now is that once I enter the iPhone pixel dimensions (750 x 1334) the generator circle is ALWAYS cut off on the sides! I even tried to make a little tiny circle in another project and then copy/paste it in…but it STILL gets cropped off on the sides.
I spent an hour last night trying to deal with that. I don't have MOTION, and would love to NOT have to buy it, lol, at least not yet.
