The video introduces Storyboard, an advanced editing tool designed to give users precise control over directing actions in a sequence. The tool features a familiar timeline interface at the top, where users can manage and sequence actions over time. Caption cards are used to describe the setting, characters, and actions at specific points in the clip. The video demonstrates how to set a scene by describing a red crane with a yellow tail standing in a stream, and then directing it to dip its head into the water halfway through the clip. This is achieved by creating a new storyboard card on the timeline and describing the action, which the storyboard then visualizes accurately.
