1. Give each scene a role
A scene can establish context, reveal the product, demonstrate a feature or ask for a next step. Decide which job it does before writing its visual prompt.
Use a short four-scene draft to begin. You can extend it after the basic story works.
2. Write what the camera can see
Describe the subject, setting, framing and action. ‘Close-up of the actual pump head on a cream stone surface’ is more actionable than ‘Make the product feel premium’.
Mention the details that must remain consistent: packaging color, proportions, label and the product's real appearance.
3. Separate picture, voice and text
Use the visual field for the scene, the voiceover field for spoken words and the caption field for what must be read. Repeating the whole narration on screen can make a short shot crowded.
Read the lines aloud against the scene duration. Shorten the words or extend the shot when they do not fit naturally.
4. Save before generating
Review and save the storyboard before generating scene assets. If only one frame is wrong, generate a replacement for that scene rather than rewriting a working story.
A good storyboard makes the review easier: you can compare the intended shot with the produced result.
