. Every eighth line down is marked thicker than the rest and shows half a foot of film. One second of animation would take three of these sections. Sound breakdown was often done on separate sheets called bar sheets made by the editor, and given to the animator who would transpose them to his dope sheet.

Layout

The typical dope sheet is divided into five sections which are separated by many vertical and horizontal lines, the horizontal lines represent one frame of film while the vertical ones separate the sections:

1. The column on the far left is used by the animator to jot down notes on the path of the action and their thoughts about how the action should be visualized.
2. The next column is used to write down any dialog that may be happening in the scene. The sound is split up into its phonetic components and marked down in the frame that it appears in in the film.
3. The central section is split up into six smaller columns, each one representing one level of animation. Animation should never exceed five levels of acetate, any more and it will be too thick to see through. The numbers of the drawings are marked down in the order they are to be shot in while the sixth column is for the background.
4. The final column is for camera instructions, giving information for panning
