Design the shot before you generate it. Block a scene in rough 3D, direct a real film camera — lens, framing, keyframed moves — or walk the camera with your phone in AR, then export a clean reference for AI video models like Seedance, 2.0 Built by a camera operator who was tired of prompting a move and getting the wrong one back. The Blocks export mode works best when your actors move — it gives the model less to copy, so bodies actually animate.
Hey Product Hunt 👋
I've worked as a camera operator in film for about 10 years. When I started making AI video, the thing that always broke it for me was camera control. A simple move is fine, the model handles that. But the moment you want something more complex, a move that builds, that changes speed, that hits a beat at the right second, it falls apart. The timing never lands where you want it, and if you ask for a handheld feel, the model just ignores you and gives you something smooth.
So I built GREYSET. You block the scene in rough 3D, set your lens and aspect ratio, and keyframe the exact camera move, with the timing you actually want. Or you open it on your phone and literally walk the shot in AR, and your phone becomes the camera. Then you export all of that as a clean reference for whatever video model you use, like Seedance 2.0
The part I still can't get over is that the handheld feel from actually walking carries into the render almost 1:1. That little bit of human shake survives, which prompting never gave me.
It's free to try. I'd genuinely love your honest feedback, good or bad. What would you want it to do?
