The advanced preferences are shown in Figure 11.13, “Advanced preferences”.

Show experimental audio processors adds some extra audio processors whose quality has not been fully checked. If you try them out it's advisable to listen to the results in a cinema or good 5.1 listening environment to check that they give you what you want.

Only servers encode makes DCP-o-matic encode JPEG2000 data only on encoding servers and not on the host. We suggest you leave this unticked unless you have a good reason to do otherwise.

Maximum number of frames to store per thread sets how many frames will be queued up in memory when they cannot yet be written to disk. Changing this value will make DCP-o-matic use more memory, but may make it more efficient when you have a lot of CPU cores or network encoding servers.

With the filename format fields you can adjust the filenames that are used for metadata (CPL and PKL files) and assets (MXF and subtitle files). Below each field there is a list of the ‘magic’ values that you can use in the format and an example of a filename that you might see with your current settings.

The checkboxes labelled Log control what sort of messages DCP-o-matic writes to its log file when creating a DCP. It is useful to leave General, Warnings and Errors ticked as this makes the log files useful for tracking down bugs.

The Timing checkbox will enable extra log entries to allow developers to investigate and optimise the speed of DCP-o-matic. It will significantly increase the size of the log files that are generated, so in normal use it is best to leave this unticked.
