Rank Key Settings.
This page allows you to choose what you would like to use for the various ranking titles in your log. As you can see in the graphic below, the default values are N/G, OK, * and **. You can change these to anything you like. Keep in mind that Rank 1 is the best and Rank 4 is the worst. The values that you assign will also be used in the making of an export file to separate the clips you wish to include.
