VFX lead on set — bridges director and VFX studio, oversees greenscreen lighting, tracking markers, and logs all CG requirements. Your point man for digital effects during shooting.
The Digital Effects Supervisor stands on set between the director, cinematographer, and the VFX studio—a position often underestimated but crucial for the quality of the subsequent digital work. You'll see them walking around the set with a tablet, measuring tape, and checklist. Their task: to ensure all information for post-production is captured before the lights go out and the sets are dismantled.
Specifically, this means tracking—the digital markers, color references, and geometry data that will later enable the reconstruction of the 3D space in the studio. The supervisor monitors that the greenscreen or bluescreen areas are properly lit, have no hotspots, and maintain color consistency across multiple takes. They document lighting setups, lens focal lengths, sensor parameters—everything the VFX artists will later need to credibly integrate their digital elements into the live-action footage. For motion capture shoots, they ensure the markers are clearly visible and that the system's calibration remains stable throughout the entire shooting period.
Communication is their primary tool. The supervisor must understand the director and DP—what the effect requires, where the artistic ambition lies—and simultaneously translate that into concrete technical requirements for the VFX studio. They are the first point of contact for questions like: Can we digitally replace this background later? Do we need more reference material for this CGI creature? Is the current lighting sufficient for keying, or do we need to adjust? Good communication here saves hundreds of thousands of Euros later in costly rework and reshoots.
Practically, this also means: The supervisor maintains a detailed VFX logbook, photographs each setup from multiple angles, records scale references, and creates a so-called VFX Readiness Document before each shoot—a checklist that ensures nothing technical is overlooked. For complex shots, such as those involving camera tracking or multi-layered greenscreen combinations, they often collaborate with the studio's VFX supervisors in advance to plan the exact workflow. They act as the buffer between the set and the studio, preventing precious shooting days from being wasted and ensuring the VFX supervisor doesn't later struggle with incomplete or unusable data.
