Send screeners you can trace

A screener goes to dozens of people: festival programmers, distributors, sales agents, press, cast and crew. Every one of them is someone you chose to trust, and every one of them is a point of failure. When a cut turns up somewhere it should not be, the usual position is that it could have been any of them.

Burned-in visible watermarks are the traditional answer, and they do work. They also cost you something. They're ugly, they distract the exact people whose job is to judge the film on its merits, and they're the first thing a determined leaker crops out.

Instead of one marked master, you issue one file per recipient. Each carries a different invisible identifier, woven into the image data itself. Not the filename, not the metadata, not a header that a re-encode would strip. Nobody can see it, including the recipient, and no two copies look any different from each other.

When a file surfaces, you run it back through the detector. It recovers the identifier and tells you which copy you're holding. The evidence travels inside the picture, so it arrives with the leak.

A leaked screener is rarely a pristine file. It has been recompressed, resized, screenshotted, filmed off a monitor, or passed through a platform that re-encodes everything it touches. A mark that only survives a clean copy is not much use.

So we publish the actual numbers instead of adjectives. One photograph, one invisible ID, 11 attacks: recompression down to low quality, resizing to a quarter scale, screenshots, social re-uploads, rotation, and crops that throw away three quarters of the frame. The AI watermark came back from 11 of 11, and every confidence figure is real decoder output on the exact file shown beside it.

You can go through it attack by attack on the robustness demo.

Screeners are video, so video watermarking is the part that matters. It's included in the Premium tier at $20/month, along with the AI method, which is the one built to survive being handled. The free tier is there so you can satisfy yourself the thing works before paying for it.

There's no per-recipient licensing charge and no enterprise sales call. Full pricing is on the home page.

It does not stop a leak. Nothing does. Someone determined to put your film on the internet can still do it, and any watermark can be destroyed if the file is degraded far enough. At that point what's circulating is a bad copy of your film, which is its own kind of answer.

What it changes is the arithmetic. A recipient who knows their copy is individually identifiable behaves differently from one who believes they're anonymous in a crowd of fifty. Most screener leaks aren't sophisticated attacks. They're someone forwarding a file because they assumed it couldn't be traced.
