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.
