+<title>Templates</title>
+
+<para>
+If you frequently make DCPs with similar settings you may find it
+useful to use templates.
+</para>
+
+<para>
+Say, for example, you often make 4K feature DCPs from video files in
+’scope at 25fps. You can speed up this process by following
+these steps:
+</para>
+
+<itemizedlist>
+ <listitem>Create a film with any content and set it up how you like;
+ in our example, set the content to scale to DCP, the DCP resolution
+ to 4K, and so on.</listitem>
+ <listitem>Choose <guilabel>Save as template...</guilabel> from the <guilabel>File</guilabel> menu.</listitem>
+ <listitem>Enter a name for your template.</listitem>
+</itemizedlist>
+
+<para>
+Then in the future you can create a new film, tick the
+<guilabel>Template</guilabel> box and choose your previously-saved
+template. The basic film's settings will come from your template, and
+when you add some content it will take on the settings of the
+first similarly-typed piece of content in your template.

+<title>Common tasks</title>
+
+<para>
+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.
+</para>
+
+<section>
+<title>Adding subtitles to an existing DCP</title>
+
+<para>
+You have three options:
+</para>
+
+<itemizedlist>
+<listitem>Make a “Version File” (VF) DCP.</listitem>
+<listitem>Make a complete DCP with projector-added subtitles.</listitem>
+<listitem>Make a complete DCP with burnt-in subtitles.</listitem>
+</itemizedlist>
+
+<para>
+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.
+</para>
+
+<para>
+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.
+</para>
+
+<para>
+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.

+<section>
+<title>Adding soundtracks or subtitles in different languages</title>
+
+<para>
+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:
+</para>
+
+<itemizedlist>
+<listitem>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).</listitem>
+<listitem>For each language, make a new Version File (VF) DCP which refers to the OV.</listitem>
+</itemizedlist>
+
+<para>
+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.
+</para>
+
+<para>
+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.
+</para>
+
+<para>
+The full details of OV and VF files are discussed in <xref linkend="sec-overlay"/>. The steps can be summarised as follows:
+</para>
+
+<itemizedlist>
+<listitem>Create a new DCP-o-matic project for the OV, as normal, adding video and perhaps sound. Make the DCP.</listitem>
+<listitem>Create a new DCP-o-matic project for the VF.</listitem>
+<listitem>Use <guilabel>Add folder...</guilabel> to add your OV DCP to the project.</listitem>
+<listitem>Select the video tab and tick <guilabel>Refer to existing DCP</guilabel> (you may need to select <guilabel>By video content</guilabel> for <guilabel>Reel type</guilabel> in the <guilabel>DCP</guilabel> tab).</listitem>
+<listitem>Do the same in the <guilabel>Audio</guilabel> tab if your OV has audio.</listitem>
+<listitem>Add your language-specific audio and/or subtitles and Make DCP.</listitem>
