This paper shows how to make long, camera-controlled videos much faster by generating only a few smart keyframes with diffusion, then filling in the rest using a 3D scene and rendering.
VideoAR is a new way to make videos with AI that writes each frame like a story, one step at a time, while painting details from coarse to fine.
SS4D is a new AI model that turns a short single-camera video into a full 3D object that moves over time (that’s 4D), and it does this in about 2 minutes.
