+<title>Frame rates</title>
-<para>This chapter describes some parts of DCP-o-matic that are
-probably not essential, but which you might find useful in some
-circumstances.
+<para>
+In an ideal world, a DCP would be created using content at the same
+video frame and audio sampling rates as the DCP. This is not,
+however, always possible.
</para>
<section>
-<title>Scaling</title>
+<title>DCP rate limitations</title>
<para>
-If your source material is not of the DCI-specified size, or if it
-uses non-square pixels, DCP-o-matic will need to scale it. The
-algorithm used to scale is set up by the <guilabel>Scaler</guilabel>
-entry in the film setup area. We think ‘Bicubic’ is the
-best all-round option, but tests are ongoing.
+There are some limitations to video and audio rates in DCPs. This is
+complicated by the fact that not all projectors will play DCPs at the
+same rates. It is possible to create a DCP which one projector will
+play fine, but another (of a different type) will refuse to play, or
+even refuse to ingest.
+</para>
+
+<section>
+<title>Guaranteed rates</title>
+
+<para>
+The only rates that are (pretty much) guaranteed to work on all DCI
+projectors is 24 frames per second (fps) for video and 48kHz or 96kHz
+for audio. If you are sending your DCPs to unknown places it wise to
+consider using these rates if at all possible.

+<title>Other often-supported rates</title>

+<title>Adapting content to fit the DCP rate</title>
<para>
-If you have configured details of a TMS in the preferences dialogue
-(<xref linkend="ch-preferences"/>) you can upload a completed DCP
-straight to your TMS buy choosing <guilabel>Send DCP to TMS</guilabel>
-from the <guilabel>Jobs</guilabel> menu.
+DCP-o-matic has a few tricks to allow you to use content that is not
+in one of the ‘approved’ rates.
</para>
-</section>
+<para>
+Audio is easy: DCP-o-matic can resample to 48kHz from any source rate
+with minimal loss in quality.
+</para>
+<para>
+Video rate conversion is harder. DCP-o-matic's basic strategy to deal
+with a non-supported content rate is to run it at the wrong speed, and
+to adjust the audio to keep it in sync.
+</para>
+
+<para>Let us consider the example of a 25fps source for which you want
+to create a 24fps DCP. DCP-o-matic will put the frames from the
+source directly into the DCP without modification, but will tell the
+projector to play them back at 24fps. This means that the DCP's video
+will run slightly slower than the original.
+</para>
+
+<para>
+If DCP-o-matic did nothing else, the result of this would be that the
+audio would be running at the original speed with the video running
+slowly. Hence the audio would drift slowly out of sync. To avoid
+this, DCP-o-matic also resamples the audio such that the projector
+will play it too fast by the same amount. Hence it will sound
+slightly different but will remain in sync with the video.
+</para>
+
+<para>
+For very low or high frame rates, DCP-o-matic can also skip or duplicate frames.

<para>
-When evaluating the effects of different filters or scalers on the
-image quality, A/B mode might be useful. In this mode, DCP-o-matic
-will generate a DCP where the left half of the image uses some
-‘reference’ filtering and scaling, and the right half of
-the image uses a different set of filters and a different scaler.
-This DCP can then be played back on a projector and the image quality
-evaluated.
+The <guilabel>Frame Rate</guilabel> control in the
+<guilabel>DCP</guilabel> tab sets the video frame rate that the DCP
+will use. Clicking <guilabel>Use best</guilabel> sets the rate to
+what DVD-o-matic thinks is the best for your content. With this
+button, DCP-o-matic assumes that the whole range of frame rates (24,
+25, 30 and 48fps) are allowable.
</para>

-To enable A/B mode, click the A/B checkbox in the setup area of the
