The Harding Test

The Harding Test was designed to analyze videos for flashing and patterns that can cause seizures in people with epilepsy. The original online Harding Test is a paid service that offers two types of tests — instant automated and manual. If your video doesn't pass the test, the service offers to make subtle edits to the footage to correct it. It also offers other services like removal of product placement and offensive language, videotape duplication, encoding, and transcoding.
