The advantages of this +approach are that the VF is very quick to generate, and small in size, +making it easy to distribute. This is especially useful if you have +to make VF DCPs in many different languages. + + + +Making a complete DCP with projector-added subtitles gives you a new, +single DCP which the projectionist can ingest and play. It will be +the same size as your existing DCP, and fairly quick to create. This +approach relies on the projector (or server) to create the subtitles +and overlay them on the image, which mostly works well but is not +100% reliable. + + + +Making a complete DCP with burnt-in subtitles gives you a new, single DCP +but with the subtitles rendered by DCP-o-matic and copied into your +image. This is slower to create than a DCP with projector-added +subtitles as every video frame with a subtitle must be re-encoded. +The advantage of this approach is that it is less likely to go wrong, +especially if you are using unusual subtitle positioning or character +sets. + + +

+Adding soundtracks or subtitles in different languages + + +If you have a film that is to be dubbed or subtitled in several +languages, the best approach with DCP-o-matic is as follows: + + + +Make a DCP with the common elements (perhaps just the video, or maybe the video and sound); this is known as the Original Version (OV). +For each language, make a new Version File (VF) DCP which refers to the OV. + + + +Once you have done this, you send the OV DCP to every cinema and then +the appropriate VF to each cinema depending on what language they want +to play the film in. The projectionist ingests both DCPs and then plays the VF. + + + +The advantage of this approach is that the VF DCPs are much smaller +than the OV since they only have the language-specific parts. If you +are just changing the subtitles you can often ship the OV by normal +transport means (e.g. a hard drive or high-speed download) and send +the VF by email. + + + +The full details of OV and VF files are discussed in . The steps can be summarised as follows: + + + +Create a new DCP-o-matic project for the OV, as normal, adding video and perhaps sound. Make the DCP. +Create a new DCP-o-matic project for the VF. +Use Add folder... to add your OV DCP to the project. +Select the video tab and tick Use this DCP's video as OV and make VF (you may need to select By video content for Reel type in the DCP tab). +Do the same in the Audio tab if your OV has audio. +Add your language-specific audio and/or subtitles and Make DCP. + + +
+ + + + + Playing DCPs + + DCP-o-matic includes a DCP player, and although it requires a + very high-speed CPU to play DCPs in full resolution, it can also + play DCPs at reduced resolutions with slower CPUs. + + To use the player, start DCP-o-matic + Player, and load a DCP using the + Open option on the File + menu. + + If you load a VF and/or encrypted DCP you can add your OV + and/or KDM using the appropriate options on the + File menu. + + During playback the Performance area at + the bottom right of the window will give details of how many frames + are being dropped; these are frames that were not decoded from the + DCP quickly enough. If this number is high you can increase + performance at the cost of rendering quality by choosing an option + from the View menu. If you set the player to + decode at less than full resolution the DCP's data will be decoded + at this lower resolution, which is quicker than decoding at full + resolution. + + + + + + +Configuration files + +Most of DCP-o-matic's configuration is stored in an XML file called config.xml. This is stored in different places depending on your operating system: + + + Windows: c:\Users\your_user_name\AppData\Local\dcpomatic + OS X: /Users/your_user_Name/Library/Preferences/com.dcpomatic/2 + Linux: ~/.config/dcpomatic2 + + +Possible XML tags are as follows: + + + + +
