The storyboard

One sheet per clip, vertical panels in a row, each panel one action, left to right. Panels are numbered within a sheet; sheets are numbered across the video.

The sheet is always 16:9 and its panels are always vertical, whatever shape the finished video is. Neither follows the delivery ratio, and neither is the plan's to set.

The plan settles how many sheets there are, what happens in each clip and how long it runs, which images come in as references, and the look. How a clip divides into panels is settled here.

Anything the plan specifies wins. The defaults below fill gaps only.

Workflow

One sheet at a time. Run all six steps for the first sheet, then run all six again for the second, and so on. Sheets cannot be built in parallel or in one call — each prompt needs the previous sheet's finished image in hand.
