What is an overlay vehicle?
Updated June 2026 · Revolution Picture Cars
Also called composited vehicle.
An overlay vehicle is a picture car filmed separately and composited into a scene in post-production, rather than being physically present in the same location as the rest of the action.
Overlay vehicles are used when a specific vehicle is unavailable at the main shooting location, when safety or practical constraints prevent it from being on set, or when the VFX supervisor determines it is more efficient to add the vehicle digitally. The overlay vehicle is photographed with matching lighting, lenses, and movement so its post-production integration is seamless.
Example
A vehicle that could not be brought to the location is shot separately against greenscreen and composited into the plate. It looks like it was there, and the schedule never had to get it there.
Figures are illustrative, chosen to show the mechanics rather than to quote market rates.
Where you'll see it
A visual effects approach agreed in prep, requiring matched lighting and camera data on both plates.
Common mistake
Deciding to composite after the plate is shot. Matching lighting, camera height, and lens on both passes is what makes it work, and it cannot be recovered later.

- What does an overlay vehicle need from the shooting day?
- A clean plate, lighting and camera data, and often a physical stand-in on set so performers have an eyeline and the compositor has a reference for scale and contact.
- When is an overlay used?
- When the vehicle cannot reach the location, cannot be risked in the action, or does not exist except as a build or a digital asset.
