Hi I am about to make a DCDM (Digital Cinema Distribution Master) delivery for a customer. But the specifications they are asking for is giving me some challenges. Hopefully someone here has some good advice to share… I have a delivery of DCDM 16Bit Tiff files, for a feature film (The DSM is 10Bit RGB). start reel01 with frame number: 86400 (and TC 01:00:00:00) start reel2 with frame number: 172800 (and TC 02:00:00:00) And so on... Reels need to contain preeroll/48fr/firstframe, and lastframe on all reels. But the DCDM settings in the DVS Clipster I am using for doing the mastering does not have the possibility to output the wanted Framenumber/TC (Framenumber starts counting from 00000 no mater what timeline TC, or internal file TC is (This is a problem with the Clipster ONLY when I am outputting DCDM). I have been i touch with DVC service. They have told me that there is no option for choosing or offsetting frame number/TC when making DCDM in Clipster at this time. (They will after my questions now consider to make this an option for the next paid version. But that does of course not help me now). My previous experience (and also the first answer I received when I contacted DVS service) is that DCDM should me made directly from the finished DCP master (j2K files). Divided in reels. But not containing preeroll/48fr/firstframe, and lastframe on the reels. But you give the customer what they ask for, and recently I have had two separate customers asking for the same DCDM specs. Personally I think they might have mixed DCDM delivery specs with DSM (Digital Source Master) specs… To solve the problem, I am thinking about using our DaVinci Resolve to make the DCDMs (There I can decide witch frame number to start on). In Resolve 9 there is an option to set render codec to: TIFF XYZ 16Bit (My test seems to look ok, but a DaVinci render is a lot slower than a Clipster render). Also one possibility can be to make a DXP RGB render in Clipster. And then use a LUT to convert the files to TIFF 16Bit XYZ while rendering (I have not tried this). DVS service says: "at the moment it is not possible to generate the files as specified by your customer ind the DCI tool. You will need to define all settings by hand in the finalize dialog. There you will need to set to RGB and set a 3D LUT manually. With name options and TC offset you can create the files as requested. You can create a separated TIFF sequence of all reels, when using the clip wise option in the finalize dialog directly from the DCP" But DVS says that they support Kodaks 3D LUT format. Kodak does not longer sell their LUT making software, and DVS will not recommend any other specific LUT software Can anyone tell me who other can make Kodak 3D LUTs? I will be thankful for any good advice! CUSTOMER DELIVERY SPECS: DCDM Hard drive – Supply Uncompressed X’Y’Z’, 16 bit, TIFF picture files taken from (1.(i)) above. Should be fully DCI Compliant. Resolution should be : theatrical ratio of 1:85:1 – 1998 x 1080 / theatrical ratio of 2:35:1 – 2048 x 858 Image should always be 24fps, textless, flat, non-anamorphic. Each reel should be as a separate file, with leaders, and textless elements The file format should be single *.tiff file per frame, named as the feature (or abbreviated), reel number, and frame number. The reel number within the file name shall be specified such that when listing, they are in sequential order. Reel 1, Frame 1 should be 086400 (1 hour) at the start of the leader Reel 2, Frame 1, should be 172800 (2 hour) at the start of the leader etc… Sound should be WAV 48 Khz, 24 bits, 24fps, 5.1 in perfect synchronisation with the image Sound layout should be the same as the image files above. Subtitles, Captions, dates, names, places etc – All subtitle and caption files should be supplied in separate film reels as XML cinecanvas files to sync with the relevant film reels, with start timecode of 00:00:00:00. Textless Elements / reels should be supplied in separate film reels, to sync with the relevant texted film reels. regards, Terje Edited: by Esteban Aguilera (only the color in the text)
Hi Terje, Dont have experience with DVS but you can use Adobe Bridge to rename your tiff files. Have used on 2 hrs feature and it's much quicker than other renaming tools. Also XYZ LUT in Resolve is from P3 colorspace to XYZ. Make sure that your material is graded in P3 colorspace. If graded on REC709 you need to solve conversion with custom REC709 to XYZ LUT.
I use 'Bulk Rename Utility' on Windows. Fast, accurate and has a huge range of options including generating continuous number sequences. Software such as LightSpace CMS can help you generate XYZ LUTs in a variety of formats. Alternatively CineSpace could be an option although currently lacks a Matrix tool which could be most useful for what you are trying to achieve. I believe it also has a number of presets that can help. Steve Shaw also offers individual LUTs if that helps? Fateh is right about the XYZ LUT in Resolve. You either need to have graded in P3 to use it, or alternatively use a custom 709 to XYZ (can be done with a gMatrix or a LUT).
