Overview

Don't fail at the final hurdle.

Broadcasters across the UK, Europe and Japan mandate that all content passes a Photosensitive Epilepsy test before transmission. Failing means immediate master file rejection — a costly delay right before delivery.

We run the industry-standard Harding FPA (Flash and Pattern Analyzer) algorithm, the same software used by Ofcom, the BBC and major Japanese broadcasters. Every frame is analysed for dangerous luminance flashes, red flashes, extended spatial patterns and stroboscopic sequences.
