Kommer Kleijn brings insight to the value of the DCP. Copied with his permission.
Recently there was a mail thread on the ISDCF reflector that included the following superb response from to a paragraph. I am writing this as a cinematographer and as a representative of IMAGO, The European Federation of Cinematographers.
- I can fully understand any festival which wants open, non-encrypted ProRes (or any other common codec) files for playing them “risk free” from a cheap playback system. The festival poeple can check the movies beforehand, if necessary at home. Ok, there is a risk of pirarcy here. But that is always there. Small movies will hardly have the legal power to follow up a piracy copy made from a DCP projection. And Hollywood doesn’t send movies to small festivals…
I know many people see encryption as the only important difference between DCP and other formats, but please let us not forget that the DCP format provides SEVERAL major functionalities (a part from image quality) that other electronic picture formats do not have.
One family of functionality is, for sure, piracy protection and the auto-destruct (time-limit) function, both provided by the encryption and KDM system.
