Captions are text fields you can edit to include special indications and notes specific to a panel in your storyboard. These text indications can be dialogue, action notes, sound effects, and more. You can customize the captions to include any information realted to your project.
When you start your storyboard from a script, the caption fields are where you will break down the script to build the various scenes, panels, sequences, and acts of your project.
To add information to a particular panel, you will use the Panel view. This view displays the different captions related to a panel, as well as other useful information.
