+  <para>
+    As well as creating DCPs from the content you specify, DCP-o-matic
+    can also export projects to ProRes and MP4 files.  This is most
+    often useful to convert DCPs to a file that is smaller and easier to play back.
+  </para>
+
+  <para>
+    To convert a DCP to ProRes or MP4, the first step is start a new
+    project and import the DCP (see <xref
+    linkend="ch-manipulating-existing-dcps"/>).  Then, choose
+    <guilabel>Export...</guilabel> from the <guilabel>Jobs</guilabel>
+    menu to open the export dialogue, as shown in <xref linkend="fig-export"/>.

+    From this dialogue you can select the required output format,
+    output file and, in the case of MP4, the quality of the output
+    file.  Higher quality files will, of course, be larger.

+    You can also choose whether to mix down multichannel sources to stereo and whether you want to write separate reels to separate files.
