Video within AI Video Generation
I have a web product demo video. Now, I want to use that and generate a AI video, in which a man is operating on a big desktop. But instead of showing random screen on the desktop, I want to show the product demo video. Since there is a slow cinematic orbit across the desktop, I even tried to integrate the demo video as an overlay on the ai video over the desktop in Adobe Premiere Pro, but as camera moves, I need to pin the demo video every keyframe using 3d effect and corner pin effect. But this is very tedious for rest of the videos I need to generate.
My question is, is there a way currently using any ai tool, in which I can embed demo video and then generate the ai video using a start image (which will be of a man operating a desktop), but desktop content should be the demo video.
