So... Placing and tracking an image on to a square surface in AE is a piece of cake. You just use perspective corner pin.
But: What does one do if the surface where one is trying to place an image on isn't totally square, but has a little curve here and there?
Like, in my case, a magazine:
I'm making a little pre-roll ad for a car mag, and I need to be able to switch out the front page once a month, so I thought shooting with a blank and then tracking an image of the front page to the surface in post would be a good idea. But even when lying flat on the ground, the magazine in my shot turned out not totally square.
I've tried all type of YouTube-searches, but haven't been able to find a tutorial on this. So help would be deeply appreciated!
