What is a clean plate, when do I need one, and how do I shoot it so it actually works?

Partially verified: the curator re-read none of the cited sources; S5, S7, S6, S3, S1 rest on the producer's pinned reading. A clean plate is the same shot filmed without the actors or unwanted items so they can be removed or replaced in post (wire and rig removal, removing part of a performer, twins by splitting the frame). It is easiest with a locked-off camera. The sources agree on the main failure modes: any change to camera settings, framing or background between passes ruins the match, and moving-camera shots need expensive motion control or reconstruction from other frames. The 2026 VES data guide has no clean-plate entry in the text read. Curator qualifications: Partially verified: the curator re-read none of the cited sources; S5, S7, S6, S3, S1 rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S5: HTTP 200, bytes differ from the producer pin; S7: HTTP 200, bytes equal to the producer pin; S6: HTTP 200, bytes differ from the producer pin; S3: HTTP 200, bytes differ from the producer pin; S1: HTTP 200, bytes equal to the producer pin. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
