+ dcpomatic2_create -o my_film --container-ratio 185 --content-ratio 185 -c FTR -n "My Film" Stuff.mp4

+Common tasks
+
+
+This chapter describes how to carry out some commonly-required tasks
+with DCP-o-matic. The full details are elsewhere in the manual: here
+we just discuss different approaches to these tasks and how to carry
+them out.
+
+
+
+Adding subtitles to an existing DCP
+
+
+You have three options:
+
+
+
+Make a “Version File” (VF) DCP.
+Make a complete DCP with projector-added subtitles.
+Make a complete DCP with burnt-in subtitles.
+
+
+
+Making a VF DCP is usually the best option. This will be a very small
+DCP which contains only the subtitles: it refers to your existing DCP
+for the picture and sound. The projectionist will ingest both the
+existing and VF DCPs and play back the VF. 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.
+
+
+
+Making a VF DCP
+
+
+Start a new DCP-o-matic film.
+Click Add DCP... and specify your existing DCP's folder.
+Go to the DCP tab and choose Split by video content for Reel type.
+Go to the Video and
+Audio tabs in turn and tick the Use this DCP's audio as OV and make VF checkboxes.
+Add your subtitles to the film in whatever format you have.
+Check the subtitle appearance in the preview; it will be
+slow to respond as it is having to decompress images from the existing
+DCP.
+Choose Make DCP from the menu.

+
+
+
+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 and verifying 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.
+
+
+
+ The player also offers a simple DCP validator. To check a DCP,
+ open it and then select Verify DCP from the
+ Tools menu. This will run some basic checks to see if the DCP meets the required standards.

+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
