A working prompt pack for generating short-form SaaS/product ads with Seedance-class AI video models.
It gives you the directorial order that actually works — subject and action first, camera language second, sound third, transitions last — plus 10 fill-in-the-blank templates (product reveal, before/after, feature loop, testimonial b-roll, UI-in-hand, and more). Each template is annotated so you understand why each beat is where it is, not just what to paste.
How to use: open README.md, pick the template that matches your ad, swap the {{bracketed}} slots for your product, and run it. The structure.md file explains the grammar so you can write your own beyond the templates.
