Process Trailer
O que é Process Trailer?
A process trailer is a flat platform towed by another vehicle, carrying actors in a stationary car so the camera crew can safely film them from all angles whilst simulating a driving scene.

Como se compara
A process trailer carries the performance vehicle and the actors, keeping them static relative to the camera, whilst the tow vehicle drives. A camera car carries only the camera and crew, actively driving alongside or near a performance vehicle that is being driven independently. Process trailers are used for dialogue and performance capture in vehicle interiors; camera cars are used for exterior shots of vehicles in motion.
Pense nisso como…
A process trailer is like the moving walkway at an airport: from the perspective of the person on it, they are moving through a world that passes around them, but they are actually standing still on a platform being carried through space. The performance happens in a fixed, controlled environment whilst the illusion of movement is supplied by the world around them.
Dica profissional
When integrating AI-generated or extended background plates into process trailer footage, ensure the tow vehicle speed and turning data are logged precisely during the shoot: this information dramatically improves the accuracy of the background plate perspective calculation and any subsequent AI-driven scene extension.
Tipos e variações
- The standard process trailer is a flat deck towed by a camera car or standard tow vehicle, with the performance car mounted centrally and cameras rigged around it.
- High-sided process trailers include low walls or rails to provide additional security and to conceal rigging from camera.
- Some process trailers are designed to accommodate multiple vehicles side by side, allowing filming of conversations between actors in different cars.
- Variations exist for motorcycles, where the bike is mounted to a low platform and the rider performs without controlling the machine.
- Modern productions may mount the entire trailer assembly on an LED volume stage rather than towing it at all, using a static process trailer as a mounting rig with a moving digital background replacing any practical travel.

- The process trailer is used in virtually every major film and television production that involves dialogue or performance inside a moving vehicle.
- The technique allows directors to capture precise, repeatable performances without the safety risks of actors or cameras in an uncontrolled moving vehicle.
- It is particularly essential for night driving sequences, where matching exterior lighting with background plates is more achievable in a controlled environment.
- Action sequences that require complex camera positioning around a vehicle also rely on process trailers, as the rig allows cameras to be placed in positions that would be dangerous or impossible in a freely driven vehicle.
