How it works
During approvals, sensitive and highly confidential images are circulated to cast, agents and publicists for review. A watermark — typically a semi-transparent caption, logo or “for approval only” notice laid over the frame — makes clear that the image is a review copy, not a release version.
The point is deterrence and traceability. A visible mark discourages anyone from screenshotting and sharing a frame before sign-off, and signals that the image is pre-release. Some workflows personalise the mark per recipient, so a leaked frame can be traced back to its source.
Watermarks usually appear on the review set — for example on a contact sheet or talent approval platform — and are removed for the clean, full-resolution files once frames clear their kill rights and become approved key selects.
Used well, watermarking protects an unreleased shoot without slowing the review down. For where it fits in the process, see our guide to how talent image approvals work.
