As part of various broadcasters requests media provided for broadcasting environment must be PSE (Photosensitive Epilepsy) free. There should be not frames sequences that could trigger that symptoms.

I would like to know if there exists some free software for quality check media in mov, mp4 and mxf with dnxhd, h264 and prores codecs and if ffmpeg can do it showing the possible harmful patterns and passages.



Unfortunately, I don't know of any free software that checks for PSE. As of 2013, the test for PSE was only available closed source. However, all of the major commercial QC tools can check for it. (You would need to check with each vendor if it is supported for all of the codecs you need to QC.)


Some Broadcasters require a Harding Test which is patented and proprietary, it creates a Certificate; thus getting someone to accept liability isn't going to be free.

You can find a number of places online that will test a video file (or Game, Poster, Art, etc.) but those aren't free, the Harding website has authenticated tests and support.

Free software claiming to perform the same checks (so when you submit your work, it won't be rejected) is available from the University of Maryland in the form of PEAT, their Photosensitive Epilepsy Analysis Tool.

Note: Restrictions on use

The Photosensitive Epilepsy Analysis Tool (PEAT) was developed to provide a free resource for Web designers and computer software developers. Use of PEAT to assess material commercially produced for television broadcast, film, home entertainment, or gaming industries is prohibited. For broadcast, film, home entertainment, and gaming applications, the Harding FPA software should be employed.

To get the real thing, a Certificate, you'll need to pay. To get software that claims to do the same thing without accepting liability or providing the authentic Certificate is possible, I found that source with less than 10 min. of searching.

  • Actually I need a software being able to inspect and show me problems, I don't care about certifications because the checks are done into the broadcast company itself. I have the options of create a certificate and attach it with the media but I will not use it. – user3450548 Nov 27 '17 at 10:50
