Turn 3D Previs into Real Video

Upload a Blender render or grey-box previs. H3 Max keeps its layout, camera movement and timing, and renders the scene as photorealistic footage.

Grey-box previs to final shot

Same camera, same timing: the first clip is the input, the second is what H3 Max made from it.

Source480P5s

Input: grey-box previs

A Blender-style blockout of a car on a city street (made with H3 Max Turbo for this demo). This is the clip you upload.

Untextured grey clay 3D blockout render in a Blender viewport: a simple grey box car drives straight down a road between tall and short grey block buildings. Flat neutral lighting, no textures, no colors, plain grey ground plane. The camera tracks alongside the car at street level, smooth previs animation.

Output: rainy neon Tokyo

H3 Max keeps the layout, the tracking camera and the car's path, and turns the boxes into a red sports car and lit-up shops. The prompt only says what the shapes are.

The grey box car is a glossy red sports car speeding through a rainy neon-lit Tokyo street at night. The grey blocks are glass skyscrapers and shops covered in glowing Japanese signs. Wet asphalt reflects the neon lights, light rain falls.

What H3 Max 3D to Video does

Built on fal.ai's H3 Max 3D-to-video endpoint.

Follows your previs

Scene layout, camera movement, motion and edit timing come from your clip.

Up to 15 seconds

Use a source clip of up to 15 seconds and 32 shots; the output has the same length.

Your look, or one made for you

Add up to 8 reference images, or let the model create 2 appearance references automatically.
