+The folder that you choose should have plenty of free disc space
+available. As a very rough guide, you will need about 25Mb per second
+of your DCP. This works out at 1.5Gb per minute, or 90Gb per hour.

+
+<para>
+If you always create your DCPs in a particular folder, you can use
+DCP-o-matic's <guilabel>Preferences</guilabel> to make life a little

+<title>Setting up the content</title>
+
+<para>
+Now there are a few things to set up to describe how the content you just added should be used.
+created. The settings are divided into four tabs: video, audio, subtitles and timing.
+</para>
+
+<section>
+<title>Video content tab</title>
+
+<para>
+This tab contains settings related to the video (i.e. the picture) of your content, as shown in <xref linkend="fig-video-tab"/>.
+</para>

+<figure id="fig-video-tab">
+ <title>Video settings tab</title>

+ </mediaobject>
+</figure>
+
+<para>The default values in this tab are fine for our example, but the
+options are described here anyway.</para>
+
+<para>
+The first option on this tab is the ‘type’ of the video.
+This specifies how DCP-o-matic should interpret the video's image.
+<guilabel>2D</guilabel> is the default; this just takes the video
+image as a standard 2D frame. The other options allow the video to be
+interpreted as 3D; this is described later in the manual.
+ XXX: link
+</para>
+
+<para>
+The ‘crop’ settings can be used to crop your content,
+which can be used to remove black borders from round the edges of DVD
+images, for example. The specified number of pixels will be trimmed
+from each edge, and the content image in the right of the window will
+be updated to show the effect of the crop.
+</para>
+
+<para>
+The <guilabel>Scale to</guilabel> option governs the shape that
+DCP-o-matic will scale the content's image into. Select the aspect
+ratio that your content should be presented in.
+</para>
+
+<para>
+The ‘filters’ settings allow you to apply various video
+filters to the image. These may be useful to try to improve
+poor-quality sources like DVDs. We will discuss filtering later in the manual.
+ XXX: link
+</para>
+</section>
+
+<section>
+<title>Audio tab</title>
+
+<para>
+This tab contains settings related to the sound in your content, as shown in <xref linkend="fig-audio-tab"/>.
+</para>
+
+<figure id="fig-audio-tab">
+ <title>Audio settings tab</title>
+ <mediaobject>

+</figure>
+
+<para>
+Once again, these settings can be left at their defaults for our Sintel example.
+</para>
+
+<para>
+The <guilabel>Show Audio</guilabel> button will instruct DCP-o-matic
+to examine the audio in your content and plot a graph of its level
+over time. This can be useful for getting a rough idea of how loud
+the sound will be in the cinema auditorium. The audio graphic is
+discussed in more detail later in the manual.
+ XXX: link
+</para>
+
+<para>
+‘Audio Gain’ is used to alter the volume of the
+soundtrack. The specified gain (in dB) will be applied to each sound
+channel of your content before it is written to the DCP.
+</para>
+
+<para>
+If you use a sound processor that DCP-o-matic knows about, it can help
+you calculate changes in gain that you should apply. Say, for
+example, that you make a test DCP and find that you have to run it at
+volume 5 instead of volume 7 to get a good sound level in the screen.
+If this is the case, click the <guilabel>Calculate...</guilabel>
+button next to the audio gain entry, and the dialogue box in <xref
+linkend="fig-calculate-audio-gain"/> will open.
+</para>

+ <imagedata fileref="screenshots/calculate-audio-gain&scs;"/>
+ </imageobject>
+ </mediaobject>
+</figure>
+
+<para>
+For our example, put 5 in the first box and 7 in the second and click
+<guilabel>OK</guilabel>. DCP-o-matic will calculate the audio gain
+that it should apply to make this happen. Then you can re-make the
+DCP (this will be reasonably fast, as the video data will already have
+been done) and it should play back at the correct volume with 7 on
+your sound-rack fader.
+</para>
+
+<para>
+Current versions of DCP-o-matic only know about the Dolby CP750. If
+you use a different sound processor, and know the gain curve of its
+volume control, <ulink url="mailto:cth@carlh.net">get in
+touch</ulink>.
+</para>
+
+<para>
+<guilabel>Audio Delay</guilabel> is used to adjust the synchronisation
+between audio and video. A positive delay will move the audio later
+with respect to the video, and a negative delay will move it earlier.
+</para>
+
+<para>
+The <guilabel>Audio Stream</guilabel> option allows you to select the
+audio stream to use, if the content contains more than one. There
+might be different soundtrack languages, for example.
+</para>
+
+<para>
+The final section in the audio tab is the ‘audio map’.
+This governs how sound from the content will be arranged in the DCP.
+Our Sintel clip is in 5.1, so DCP-o-matic will default to assigning
+each channel from the content to the appropriate DCP channel. This
+audio mapping is described in more detail later in the manual.

+<section>
+<title>Subtitles tab</title>
+
+<para>
+This tab contains settings related to subtitles in your content, as shown in <xref linkend="fig-subtitles-tab"/>.
+</para>

+ </mediaobject>
+</figure>
+
+<para>
+DCP-o-matic will extract subtitles from the content, if present, and
+they can be ‘burnt into’ the DCP (that is, they are
+included in the image and not overlaid by the projector). Note that
+DVD and Blu-Ray subtitles are stored as bitmaps, so it is not possible
+(automatically) to use non-burnt-in subtitles with these sources.
+Select the <guilabel>With Subtitles</guilabel> checkbox to enable
+subtitles. The <guilabel>offset</guilabel> control moves the
+subtitles up and down the image, and the <guilabel>scale</guilabel>
+control changes their size.
+</para>
+
+<para>
+All being well, future versions of DCP-o-matic will include the option to
+use text subtitles (as is the norm with most professionally-mastered
+DCPs).

+
+<section>
+<title>Setting up the DCP</title>
+
+<para>
+Now that we have set up the content that will go into our DCP, we can
+set things up for the DCP itself. This is done from the
+<guilabel>DCP</guilabel> tab which can be found at the top of the
+DCP-o-matic window (next to the <guilabel>Content</guilabel> tab).
+The DCP tab is shown in foo.
+</para>
+
+ XXX: DCP tab
+
+<para>
+The first thing here is the name. This is generally set to the title
+of the film that is being encoded. If <guilabel>Use DCI
+name</guilabel> is not ticked, the name that you specify will be used
+as-is for the name of the DCP. If <guilabel>Use DCI name</guilabel>
+is ticked, the name that you enter will be used as part of a
+DCI-compliant name. Set the name to something useful, like
+‘Sintel’.
+</para>
+
+<para>
+Underneath the name field is a preview of the name that the DCP will
+get. To use a DCI-compliant name, tick the <guilabel>Use DCI
+name</guilabel> checkbox. The DCI name will be composed using details
+of your content's soundtrack, the current date and other things that
+can be specified in the DCI name details dialogue box, which you can
+open by clicking on the <guilabel>Details</guilabel> button.
+</para>
+
+<para>
+If the DCP name is long, it may not all be visible. You can see the
+full name by hovering the mouse pointer over the partial name.
+</para>
+
+<para>
+The <guilabel>Container</guilabel> option sets the ratio of the image
+in the DCP. If this ratio is different to the ratio used for any
+content, DCP-o-matic will pad the content with black. In simple cases
+this should be set to the same ratio as that for the the primary piece
+of video content. Alternatively, you might want to pillarbox a small
+format into a Flat container: in this case, select the small format
+for the content's ratio and ‘Flat’ for the DCP.
+</para>
+
+<para>
+Next up is the content type. This can be
+‘feature’, ‘trailer’ or whatever; select the
+required type from the drop-down list.
+</para>
+
+<para>
+The <guilabel>Frame Rate</guilabel> control sets the frame rate of
+your DCP. This can be a little tricky to get right. Ideally, you
+want it to be the same as the video content that you are using. If it
+is not the same, DCP-o-matic must resort to some tricks to alter your
+content to fit the specified frame rate. Frame rates are discussed in more detail later.
+ XXX: link
+</para>
+
+<para>
+The <guilabel>Use best</guilabel> button sets the DCP video frame rate
+to what DCP-o-matic thinks is the best given the content that you have
+added.
+</para>
+
+<para>
+The <guilabel>Audio Channels</guilabel> control sets the number of
+audio channels that the DCP will have. If the DCP has any channels
+for which there is no content audio they will be replaced by silence.
+</para>
+
+<para>
+The <guilabel>3D</guilabel> button will set your DCP to 3D mode if it
+is checked. This is discussed later.
+ XXX: link
+</para>
+
+<para>
+The <guilabel>Resolution</guilabel> tab allows you to choose the
+resolution for your DCP. Use 2K unless you have content that is of
+high enough resolution to be worth presenting in 4K.
+</para>
+
+<para>
+The <guilabel>JPEG2000 bandwidth</guilabel>; setting changes how big the final
+image files used within the DCP will be. Larger numbers will give
+better quality, but correspondingly larger DCPs. The bandwidth can be
+between 50 and 250 megabits per second (MBps).
+</para>
+
+<para>
+Finally, the <guilabel>scaler</guilabel> is the method that will be used to scale up
+your content to the required size for the DCP, if required. We will
+discuss the options in more detail later; Bicubic is a fine choice in
+most situations.
