A MoCo rig is a robotic arm (like a Bolt or a Milo) that repeats the exact same move with 0.01mm accuracy, 100 times in a row.
Shoot a whip pan to black (or to a wall). In post, the VFX artist can stitch two completely different worlds together on that single blurred frame. It’s invisible editing inside the camera move. hollywood camera work - vfx for directors
Whip pans (snapping the camera so fast everything blurs) are a VFX editor’s best friend. You can use them to hide a seam between a live-action plate and a CG environment. A MoCo rig is a robotic arm (like
Let’s analyze a specific shot:
One of the primary values of the "VFX for Directors" series is its ability to translate "Technician" into "Director." On a typical set, the VFX Supervisor is a critical presence, but for a director without training, their notes can sound like a foreign language: "We need more parallax," "We’re losing the tracking markers," or "The dynamic range is too low for a sky replacement." It’s invisible editing inside the camera move
Never call "Cut!" immediately after the action ends. Hold the camera move for an extra 5 seconds. That "tail" allows VFX trackers to solve the camera’s movement in 3D space with mathematical certainty.
The camera dictates the physics of the effect. If your camera moves like a documentary, but your VFX move like a video game, the audience will sense the lie.
