    DCP encrypted file to un encrypted file

    Netcommercial Community Member

      Hi All,

       

      I have a collegue who has a movie and the person who for whatever reason encrypted the file. I was hoping to import then re export the file using CS6 as an unencrypted file, for delivery.

      After reading a bit about it, it is suggested or instructed to export the DCP onto it's own HDD for whatever type of Projector it is to be played back on.

      Is that the case? Or as I recieved the file a "dropbox" may I just re-render the file via ME and export it as an un encrypted file?

       

      If so, please if you would, share with me the steps or resource to do so and maybe some heads up on what to watch out for.

      Thanks for any direction on this one

      Regards

          I don't believe Adobe makes any tools that can handle DCP files.  That's what get's delivered to the theater for projection.  All of Adobe's tools are for use before that stage.

              Yeah, you'll notice the Adobe tools come into play before the DCP package is created, not after.

                Hello there.  I wrote the Treepot DCP guide linked above.  I have some experience with the creation of DCPs using free tools (e.g. OpenDCP).  Could you clarity your question?  Is it the case that you have an encrypted DCP package that you want to edit/import/convert to another format?

                  Hi JP,

                  Thanks for taking the time to ask. I was wondering about the whole process. I read your stuff (great info BTW) However, I did some further searching and found that ( I may be mistaken?) the encrypted key that is used to 'unlock' the file to preview it. Does have a limited amount of time and or times to access it. So one could get locked out, or miss the window to view it? Correct me if I am wrong please.

                  Also, if all were perfect, window and code to unlock the file; when exporting it, must I export it to a hard drive projector friendly? Or can I just export the file and if the person receiving the file just places it on a hard drive that the 'type' of projector being used is copasetic with?  OR is there a format issue that is required for that HDD? I hope this was clear. Thanks again

                    Yes.  Encryption is used to limit how the DCP is played.  If I understand correctly, the key can used to unlock the DCP for a specific period or for a number of plays.  DCP is typically a final delivery format for theatres with DCP servers and projectors and is probably not the best format to start with if you want to edit a film.  You can create playlists from different DCPs on the server attached to a projector in a theatre but if it is editing you want to do, I would recommend requesting your source in a more edit-friendly format, perhaps a ProRes or DNxHD file.

                      JP,

                       

                      Yes, I agree that an un-encrypted files without play back limitations would be the Ultimate for editing.... thank you for re-assuring me that I can in fact be locked out of an encrypted file as aforementioned.

                      It still leaves me in the dark in refrence to HDD format / delivery. Notwithstanding de-crypting it. Will there be a format issue on the other side of the pond if i upload the file and have the reciever place it on a sanctioned HDD, or must the HDD be formatted at export to avoid corruption?

                        I would assume the same limitations that I have experienced in Canada will apply.  Basically, it depends on the server.  I have tested Dolby and Doremi.  The safest bet, so far, is to format the drive ext2 to maximize compatibility.  As I stated in the guide, the Dolby server was able to read mac formatted HFS but the Doremi server wasn't able to.  Both servers were able to read ext2 formatted drives.  Hope that helps.  Also, if you encounter any other servers and combinations of drive formats, let me know so I can add it to the guide with a reference and thanks for your contribution so that other folks can benefit from your testing.

                          Thanks JP I won't be messing with this question in the near future. I told him he would need to look elsewhere for help on this decrypt and format as this was a  month ago. He needed it done in a couple of weeks. I suggested you BTW... I will keep in mind,  I should format as you suggest onto an HDD Not just a file for someone else to do.  As from your answer it seems that is the way to go.

                          The whole thing is new to me. After reading, I would just burn it to a Bluray and call it a day. Unless it was specifically requested. Not like I am Warner Bros and doing sneek peaks. I know , not just that, but for Piracy too. Thanks again for asking
