Hi all. A filmmaker has sent me a DKDM to decrypt their DCP. I sent them the certificate chain, and unfortunately they seem to have targeted the KDM at the root cert rather than the leaf cert, so I can't "unlock" the DCP in DCP-o-matic. This particular filmmaker is in a far far away land and has been hard to get hold of, so I am worried I may not be able to get a new KDM issued in time for the screening. Is there any way to switch around the certs in DCP-o-matic so the root cert is used to decrypt? I can only see one private key in config.xml, which I assume is for the leaf cert. However, I guess a private key must have been created for the root cert too, in order to sign the intermediate cert. Does this private key get saved anywhere? If anyone is able to help, would be hugely appreciated. Many thanks, Jim

[DCP-o-matic] DCP file size:

by Clive Osbourne

Hi Carl, hope all is well with you, I'm a user of your product DCP-o-matic for two years now and I have to say that it's a very good DCP creator and one of the best according to the reviews I've seen online. I use it to create movie trailers for our cinema here in Barbados. Though I usually receive links from our movie Distributors to download their DCP trailer content for our screens, if there are any unavailable content I will go to HDtrailers.net or Thedigitaltheater.com. and download the the content if available. These trailers which I download from the two sites in the above have to be prepped for DCP export which I use the DCP-o-matic DCP creator to finish the trailer. DCP file size: ( Distributors content file size vs DCP-o-matic file size.) My observation of file size that the trailer content downloaded via link from our Distributors have a greater file size than any trailer content that I create using the DCP-o-matic creator. I understand that the Distributor's content are mastered in Dolby 5.1 and mixed in a facility studio with 5.1 audio track stems and full 2k video content that is then exported to DCP with very expensive DCP creator software like Easy DCP and Wraptor DCP. but the trailer content download from Thedigitaltheater.com that are mastered in Dolby 5.1 are copies from the good content and then converted to MKV and MP4 files that are smaller in size because of the compression of audio and video bit rates. If I convert one of these compressed trailer files to DCP using The DCP-o-matic creator, then compare it to one of the Distributors files (the exact trailer) there is always a difference in the size of the output file. Mastering in Adobe Premiere Pro and Audition: I've experimented with creating 2048x858 2K & 1998x1080 2K QuickTime video files in Premiere with maximum bit rates and bit depths for optimum picture quality, and have extracting the 5.1 files from the compressed content with Audition then export to 5.1 wav files. Then I create and export a 5.1 2k sequence file that give me a 2.9gb or a 3.0gb file depending on the length of the trailer. DCP-o-matic export: After I have imported the sequence file that I have created in Premiere into DCP-o-matic and make all the necessary adjustments then I make the DCP. After the DCP is finished, I am seeing that the file existing in the content folder is half the size of the sequence file. Example! [ imported sequence file = 3.0gb] [exported DCP folder with ASSETMAP, cpl, j2c, pcm, pkl, VOLINDEX = 1.5gb.] There is also a drop in resolutions in the exhibition of the trailer content although all DCP contents are 2K. (1) Is the compression rate set by default to 2gb alone for all contents that are approximately 2 minutes 30 seconds? (2) Or, is there something that I can do to maintain a maximum quality content and keep my file size matching the imported file size? Thanks! Best regards, Clive.

[DCP-o-matic] 2.14.12 not working on OS X 10.13.6 High Sierra

by Max Wilhelm

Hello! I am emailing you because (after upgrading) to DCP-o-matic 2.14.12, I have found that the program no longer works. I was running v 2.12.12 for quite a long time, but decided to try and upgrade when it refused to convert a large mkv file. I thought maybe it was a bug that was later fixed. However, the latest stable version on your site refuses to open on my Mac laptop. It gives me an error log (pasted below). The latest test version doesn’t even give me an error log, OS X just flat out tells me it will not open. I am running Mac OS 10.13.6 Is this a known problem? Or perhaps I am missing something Thank you so much for any help you can provide. Your software is (usually) quite incredible. -Max Process: dcpomatic2 [48755] Path: /Applications/DCP-o-matic 2.app/Contents/MacOS/dcpomatic2 Identifier: com.dcpomatic Version: 2.14.12 Code Type: X86-64 (Native) Parent Process: ???

[DCP-o-matic] Search for encode servers on several subnets

by Mattias Mattsson

Hi! I am running DoM on a computer with two network cards, eth0 and eth1. eth0 is on the 192.168.0.0/24 subnet and eth1 on 192.168.241.0/24. Encode servers started on the 192.168.0.0/24 subnet are found automatically by DoM, but none of the servers on 192.168.241.0/24. I am sure there is connectivity on this subnet between the DoM encoding computer and the clients (ping and ftp works among other things). Is there a way to instruct DoM which network interfaces and/or subnets to listen on? It would be useful to have it listen on several subnets/interfaces as well. Thanks! Best, -- -mattias

[DCP-o-matic] low coding speed Intel(R) Xeon(R) Gold 5118 CPU

by Ипатов Иван

Hello dear Sirs! For creating DCP packages we build a workstation. Specifications are point is below: 2 * Intel(R) Xeon(R) Gold 5118 CPU @ 2.30GHz 2 * KINGSTON SEDC500 SSD 1920 GB 2 * 32Gb 2400MHz RDIMM OS: Windows 10 Enterprise LTSC But we have a once problem. The speed of encoding usually is 14-15 fps. Encode servers is not use. Jpeg 2000 bandwidth for newly-encoded date is 180Mbit/s. We made is about 100 DCP projects. Sources files were always different. The speed is always about the same 14-15 fps. We noticed that the CPU load during encoding averages 60% Can you tell me what to look for why such a low coding speed? ____________________________________________ Yours faithfully, Movie Systems Engineer Ivan Ipatov tel .: +7 (914) -975-23-76 Russia Federation, 690091 Vladivostok, Primorye Svetlanskaya 31 St The network of cinemas "Illuzion" The cinema "Ocean IMAX".

by james＠discover.film

Hi Carlh, Just wondering if a PC and MAC would format DCPs differently? I delivered some to a cinema today but 6/15 didn’t show up on the cinemas system despite being able to play on dcpomatic player on my laptop. Thanks James Discover.film Somerset House, Strand London WC2R 1LA https://discover.film <https://discover.film/>

[DCP-o-matic] Changes in projector format between 2.12.x and 2.14.x?

by Jim Dummett

Hi Carl. Are there any changes in the format of the metadata.xml DCP-o-matic project file between 2.12.x and 2.14.x? I have a bunch of DCP-o-matic project files made with 2.12.10 but not encoded yet, but would like to upgrade to 2.14.8. If I attempt to open these old projects in DOM 2.14.8 in order to "Make DCP", should I expect any incompatibility/problems? Or may there be problems if I encode these old projects via command line? dcpomatic2_cli --config /path/to/config /path/to/dom/project Cheers! Jim

[DCP-o-matic] DCP Editing

by Richard Fox

Hi, is it possible to remove a segment of an existing DCP? I would like to remove 1 minute of video and audio (same scene) from an existing DCP to create a shorter version. If this is possible, how may I do so? Thanks for your time. Richard Fox [http://graphics.hotmail.com/emwink.gif]
