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.
