The 7-part prompt structure for text-to-video
A fill-in template that gives any video model the seven things it needs: subject, action, setting, camera, light, style and sound. Fewer vague words, fewer wasted generations.
Camera movement vocabulary that video models understand
The 14 camera moves that generation models respond to reliably, with the phrasing that works and the phrasing that produces a wobbling mess.
Style lock: one paragraph that makes every clip look like the same film
A reusable style paragraph (stock, palette, grain, light rules) appended to every generation prompt so a series cuts together instead of looking like ten different ads.
Fewer warped hands and faces: what to change in the prompt
The prompt-side fixes for the classic generation failures (melting hands, drifting faces, extra limbs), ordered by how often each one works.
