-<title>Film tab</title>
-

-The ‘film’ tab contains settings that pertain to the whole film, as shown in <xref linkend="fig-film-tab"/>.

- </mediaobject>
-</figure>
-
-<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.
-</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>Trust content's header</guilabel> button starts off
-checked, and this means that DCP-o-matic will use the content's header
-information to determine its length. If, for some reason, this header
-length is wrong, uncheck the <guilabel>Trust content's
-header</guilabel> button and DCP-o-matic will run through the content
-to find its exact length. This may take a while for large pieces of content.
-</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>trim frames</guilabel> settings allow you to trim frames
-from the beginning and end of the content; any trimmed frames will not
-be included in the DCP.

-
-<para>
-The first option on this tab is the format. This will govern the
-shape that DCP-o-matic will make your image into. Select the aspect
-ratio that your content should be presented in. The ‘4:3 within
-Flat’ and ‘16:9 within Flat’ settings will put the
-image at the specified ratio within a Flat (1.85:1) frame, so that you
-can project the DCP using your projector's Flat preset.
-</para>
-
-<para>
-The remaining options can often be left alone, but may sometimes be
-useful. 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 ‘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>
-
-<para>
-The ‘scaler’ 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.
-<!-- XXX: link -->
-</para>
-
-<para>
-The ‘colour look-up table’ specifies the colour space that
-your input content will be expected to be in. If in doubt, leave it
-set to ‘sRGB’.
-</para>
-
-<para>
-Finally, the ‘JPEG2000 bandwidth’ 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).

-been done) and it should play back at the correct volume with 7 on
-your sound-rack fader.

-‘Audio Delay’ 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>
-By default the <guilabel>Use content‘s audio</guilabel> button
-will be selected. This means that the DCP will use one of the
-soundtracks from your content file; you can select the soundtrack that
-you wish to use from the drop-down box.
-</para>
-
-<para>
-Note that if your content's audio is mono, DCP-o-matic will place it
-in the centre channel in the DCP.
-</para>

-Alternatively, you can supply different sound files by clicking the
-<guilabel>Use external audio</guilabel> button and choosing a WAV file
-for any channels that you want to appear in the DCP. These files can

+‘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.

+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.

+Current versions of DCP-o-matic only know about the Dolby CP750. If

+<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>
+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.

+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>

+All being well, future versions of DCP-o-matic will include the option to

+<title>Setting up the DCP</title>

+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.

+
+ 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.
