I downloaded the movie after seeing it in theatre to once again enjoy it from the comfort of my home. Seeing 2160p, I thought it’s going to be a webcam rip but the title says webrip. Where is this leaked from that has Dolby Vision on a movie still in theatre?

    I’m really curious about the sanitation process. About the methods used to identify each copy, it has to be one of those cases of security by obscurity. I think it is a fascinating topic that I know nothing about.

      IIRC digital cinema files are usually DRM locked in a special format and are also imperceptibly watermarked somewhere throughout the video. They’re distributed to cinemas usually on physical hard drives/SSD’s. I don’t know anything about the security details other than that, off to YouTube it is!

        I think I also remember from a reddit thread many moon ago that they need to be internet connected somehow, and can only be played on a scheduled time slot.

      Xbox apparently used to encode a console’s serial number into the loading animation of the Xbox logo in the corner of your screen to figure out who broke NDAs within the company.

      It’s basically impossible to detect well-designed steganography (invisible watermark) unless you have access to the algorithm that writes or reads it, or multiple comparable copies of the media.

        That is what makes it so fascinating to me. Do they work with the original files? Is it possible to capture the decoded data at some point before the projector?Is the watermark still present there?

          Presumably the watermark is just going to be intractably encoded into the video file that’s shipped to the theater. Doing it any other way wouldn’t make sense.

            If that was designed by me I would change slightly colors of some insignificant details across movie to find exact copy
