There are several fields which are collectively known as panel captions. Captions are a method by which you can organize information in your project, and tie that information to a panel. The types of captions for your project are fully customizable. By default, a new project will have the following type of captions:
Dialogue: The lines of dialogue spoken by the characters in the current panel.
Action Notes: The actions performed by the characters in the current panel.
Slugging: Notes regarding the timing of dialogues and actions in the current panel. These can be added while creating the storyboard to give instructions on how to create the animatic.
Notes: Any relevent information about the current panel or the current scene, such as the scene heading, the characters and props, ambient sounds, background and foreground actions, continuity notes or, if working on a live action project, the cast, crew, props or material required to complete the shot.
