I have a few clips of panning across a pin board with white photo paper that I wanted to be able to replace with images. I did this because I thought I would be able to replace the white paper with an images I wanted to and switch the images if I changed my mind. I have attached a picture that will give an idea of what I have done. I pan through this board focusing on different parts. My question is how do I get the images to only appear in the white paper, and how can I keep the shadows and curves of the paper showing as part of the new image. Is there a way to do that? Also I have to track the shots so the images stay in place as I move around the board, do I use the corner pin tool? I am pretty new to After Effects so I would love to learn how to do this the right way. Any help will be appreciated.
Thanks in advanced.
do I use the corner pin tool?
Most likely yes, but depending on the camera move other techniques like genuine 3D-tracking or some mochaAE trickery may be required, especially when content goes off-screen. Impossible to tell from a static image. The rest is a non-issue. You'd simply overlay the images, so there's no requirement for any exta work other than matching the edges with some basic masking. Either way, I suggest you look up some tutorials based on the clues I provided.
Were you able to get this effect done yet? Did Mylenium's response help you out? Please let us know.
