+ <para>
+ The timeline window gives an overview of all the pieces of content
+ in your film, and how they are arranged. You can open the
+ timeline by clicking the <guilabel>Timeline...</guilabel> button
+ next to the content list. This will open a window like the one in <xref linkend="fig-timeline1"/>.

+
+ <para>
+ The X axis represents time, and you can see the time codes (in
+ hours:minutes:seconds) along the bottom of the window. Pieces of
+ content are represented with rectangles in the main part of the
+ window. Content containing different types of data (e.g. a MP4
+ file with video, audio and subtitles) have a rectangle for each
+ type.
+ </para>
+
+ <para>
+ Within the timeline you can select content by clicking, and drag
+ it to change its position. Right-clicking a piece of content will
+ open the content menu.
+ </para>
+
+ <para>
+ The toolbar at the top of the window offers the following tools:
+ </para>
+
+ <itemizedlist>
+ <listitem>Select — to select and move content.</listitem>
+ <listitem>Zoom in — to drag out an area that you want to see more closely.</listitem>
+ <listitem>Zoom out — to zoom out so that the window shows the whole film.</listitem>
+ <listitem>Snap — when enabled, content will snap to other content when you drag it close.</listitem>
+ <listitem>Sequence — when enabled, content will be kept in sequence, without gaps, even if some content is removed.</listitem>
+ </itemizedlist>

+
+ <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"/>.
+ </para>

+ </mediaobject>
+ </figure>
+
+ <para>
+ 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.
+ </para>
+
+ <para>
+ You can also choose whether to mix down multichannel sources to stereo and whether you want to write separate reels to separate files.
