it could be done…. i like math, but i’m not sure i like math enough to figure this one out right now…
here’s a link to the math involved, it’s not calculus by any means — actually the math is basic high school stuff, but it would take me a while to get a working expression:

you might try using the corner pin tracking on a separate layer to use as a track matte for the main footage layer to make a hole in it.
then position a copy of the footage behind that footage layer with the track matte in a way that it can fill the hole with a clean section of wall. since it’s footage ins read of a still, it might allow for the changes in lighting….

read through this thread:
https://forums.creativecow.net/thread/227/26795#26795It sounds like you are doing something very similar and the final expression posted there may work for you.

if you simply wanted to replace the poster (or cover it) with another poster, or similar shaped item, then i’d recommend either doing a corner pin track in AE or using Mocha to do a planar track (you should be able to find tutorials on both).
to remove the poster, i would try doing a similar track, but you’ll also need to create a patch that will match the surface that you are removing, and that could be pretty tricky depending on the surface… but if you can make a good patch you can likely get it to work with the tracking data from either a corner pin track or planar track, just make you patch large enough to feather the edges out a bit.

if you search the expressions for for ‘caption’ or ‘captioning’ you’ll find some basic solutions.
i think aescripts.com has some scripts to do something similar.
i also googled and found this:

compound arithmetic is similar to cc composite, it also has a hard light mode (it calls operator). not sure if it would have the same issue with collapse transformations….

I think your feather image should be square to avoid cropping. try either making the layer square in photoshop, or drop the feather into a square comp and use that comp as the particle texture.

cc glass may get you close….
first you’ll need a grid-like texture… try making a white solid, adding ball action (set the ball size to 50) and then adding solid composite (setting the solid color to black). you should get a grid of circles.
add cc glass to the layer you want to distort, in the surface settings, set the bump map to the solid with ball action, then click source and set it to effects & masks. then scrubs he softness setting and see if that will work for you.
there might be some other settings there to fiddle with, but it seems like it gets pretty close. you could also try using a different texture as the bump map.

possibly an issue with continuously rasterize… what happens if you put the text in a pre-comp?

you could create a new adjustment layer above all the layers that you want to ‘explode’ with pixel poly, then add the pixel poly effect to the adjustment layer. it will then effect all layers bellow it.
or you can take the comp you want to explode and put it in a new comp (this is called pre-comping or nesting). to do this, in the project window drag your comp onto the new comp icon and open the resulting new comp. your comp with all the layers will now be a single layer in the new comp. add pixel poly to that layer and you should also get the result you want.
