VFX lead on set and in post—oversees shooting prep, green tech, tracking markers. Bridge between director and VFX teams.
On set, there is someone who constantly shuttles between two worlds – the visible one and the one that will only appear later. The VFX Supervisor is this interface. They must already have the finished image in mind during the shoot, even though the cameras are still rolling and the green screen behind them is nothing more than fabric.
The work begins weeks before the first day of shooting. The supervisor attends storyboard meetings, discussing with the director which shots will be digitally enhanced or entirely artificial. They plan the tracking markers – those small dots or spheres in the space that will later help post-production reconstruct the 3D geometry. They talk to the cinematographer about focal lengths, about lighting on the green screen, about the height and position of objects that will be inserted digitally later. A VFX supervisor who plans this too late will end up costing hundreds of thousands of euros in elaborate roto work or flawed composites.
On set itself, they carry a tablet – on it run live preview systems that show how the green screen might look later, where the camera needs to be positioned precisely for the digital background to match. They ensure that the lighting remains consistent between takes, because the color temperature of a shadow on an actor can become a nightmare later if it doesn't match the 3D lights. They film references – photos of the location under different lighting conditions, measurements of spatial proportions, details that the VFX artist will never see at home.
In post-production, they work closely with the VFX producer and the compositor teams. They provide feedback on green screen keying, on particle effects, on color correction in the context of practical and digital elements. They are the guarantor that what the director envisioned is actually achievable – and if not, they suggest alternatives before the budget is blown.
The best supervisor is invisible. You don't see their work because everything functions seamlessly. You only see it when it has failed.
