In-Theater Anti-Piracy via Light Manipulation

In-theater piracy is the film industry’s biggest
unresolved problem. Someone walks in with a smartphone,
records the screen, and within hours the film is on
piracy platforms — destroying box office revenue,
suppressing OTT licensing prices, and bleeding the
entire creative economy.

Every existing solution addresses the problem after
the recording happens. Booster Deep Tech addresses it
at the physics layer — making the recording itself
commercially worthless.

The Principle

Anyone who has tried to film a CRT television screen
with a camera has seen the result — rolling black bands
across the recording, caused by the mismatch between
the CRT’s refresh frequency and the camera’s capture
frequency. The recorded video is unwatchable.

Booster Deep Tech’s system emulates this exact effect
on modern cinema screens through a unique optical setup
— without modifying the projector, without changing
the film content, and without any perceptible impact
on the audience in the theatre.

What the audience sees: Normal cinema. Full quality.
2% brightness variation — imperceptible to human vision.

What any recording device captures: Continuously moving
black bands across the entire frame — unwatchable,
unusable, worthless.

The Effect on Piracy Economics

A pirated copy with continuous moving bands:

• Causes headache in viewers attempting to watch it
• Causes temporary visual discomfort
• Makes the viewing experience unbearable within minutes
• Destroys repeat viewing and sharing

Over time, the audience for pirated theater recordings
collapses. The economic incentive to take the risk of
recording in a theater disappears. Piracy becomes
self-defeating — not through enforcement, but through
physics.

Validation

The results of this approach were shared with Jim Helmen
of Movies Lab, who acknowledged that the output achieved
what “many have tried and failed” to accomplish — and
requested follow-up on commercial deployment.

Version 1 of the design had 50–80% brightness impact
on the screen. The new design reduces this to 2% —
completely invisible to cinema audiences.

Booster Deep Tech is currently seeking development
capital to build and deploy the new design.
