Hi folks, not a common user of AE so if anybody thinks this is better done in another piece of software please suggest.
Have footage of a video billboard, static shot so no need to 3D track. Need to put other footage over the top of it. Now the bill board stretches round the corner of the building, so it is straight to start, curves round almost ninety degrees then goes straight again. I can do lots perspective etc stuff with footage in AE (I have CS3) but I can't seem to find a way to do pull it round the corner. Just point me in the right direction and which tools to use and I'll find the rest of the way myself.

Ok, tried some of those but the trouble is they do not give me the ability to lay in plotted points around the edge of the footage so that I can bend the middle and just use perspective distort at either end.

If the corner of the building is in the center of the video screen (even screen width on each wall), you could use a mesh warp with 1 row and 2 columns. When you move the points of the grid, be sure to drag the bezier handles back to the points (otherwise you'll have curved sides). Position and scale your footage before applying the mesh warp, then tweak these later.

This would be better done with a 3D app for the bending, and something like Syntheyes for the 3D tracking.
Really, in theory, AE can struggle to fake something, but most of the time, it's better done in a 3D app. In this case, any one (Max, LW, C4D, Maya, Soft) will do.

I recently did a similar thing with a teletype-style display on an old building.
I just created the two sides in a 3d AE comp and brought it back into the 2d space.
If you have Photoshop in CS3, you can exploree the vanishing point filter to create two planes that perfectly match your scene. You can export the file to AE, import the vanishing point point file, and replace the contents of the planes with your billboard movie.

This is my standard sigfile so do not take it personally: "For crying out loud, read the freakin' manual."

Sorry - my assumption was that the corner of the board would be rounded. If it's mitered (two planes at 90 degrees) then AE would be fine, as long as no 3D motion tracking is required.

No you are correct, the 90 degree is rounded, so in effect you have about twenty feet straight, twenty feet round the building and then same again straight. Angle is looking up so both curves are upper, as in bottom line and top line.

Hi,
I second Steve on this one. A 3D program would be best or at least Invigorator. The Zaxwerks 3D Warp might also help.
Here is an example made with Invigorator. A simple extruded path, placed on top of your clip can be mapped with whatever you like.
In case you have access to Invigorator and need more help let us know.
