I know how to use the chroma key. The problem I'm having is when I remove the green screen on a video and that part of the video moves. Basically, The video I'm using is a book opening. When it flips a few pages, a green screen appears, but the book itself (not just the page flipping) is moving at an angle. This causes a problem because the image I'm using to fill in the part where the green screen was does not move. It's a still image. So as the book moves, the black background shows and the image is in one position while the book (video) is moving in another.
I've tried using motion tracker an using key frames to reposition the image as the book in the video moves, but it looks jerky. Is there an easy way to make this look smooth?
