Building reliable AI video pipelines for commercial clients requires moving away from vague aesthetic prompts and toward rigid, deterministic instruction sets. Developer junyoung_arche argues that the biggest quality jump in AI product ads didn't come from upgrading models, but from treating prompts as shot lists rather than mood boards.

The 7-Slot Formula

The proposed structure enforces a strict order of operations for every generated clip: Subject + product detail, One action, One camera move, Lens & light, Location, Realism & style, and Duration. This framework eliminates ambiguity by forcing the creator to define physical constraints before aesthetic vibes. For example, instead of asking for 'beautiful lighting,' the formula requires specific technical inputs like '50mm lens, soft top light.'

Why Specificity Beats Adjectives

The article highlights that terms like 'amazing' or 'stunning' fail because they don't describe visible camera data. The developer provides a direct comparison: replacing 'a nice serum' with 'a 30 ml clear glass serum bottle with an ivory dropper cap' drastically improves consistency. Furthermore, the guide warns against 'and then' prompts. Asking for multiple actions in one clip causes hands to melt and bottles to change shape; splitting these into separate shots allows for precise regeneration of failed segments.

Maintaining Continuity Across Cuts

For multi-shot ads, the formula dictates that product details, lens, light, and location strings must remain identical across all prompts. Only the action and camera move should change. If using image-to-video workflows, the author advises against re-describing the product entirely, as this invites the model to reinterpret the source material. Instead, prompts should focus solely on motion, such as 'The camera slowly moves closer,' while letting the source image dictate the static visual elements.

Key Takeaways

  • Split Actions: Never combine multiple physical movements in one prompt; treat every 'and then' as a new shot.
  • Remove Text: Do not include copy, prices, or logos in AI video prompts; add these in post-production to avoid distorted letters.
  • Lock Variables: Copy-paste the exact product and lighting sentences for every shot to ensure visual continuity.
  • Define Duration: Explicitly set the duration in both the prompt text and the generation tool settings.

The Bottom Line

This approach transforms AI video generation from a slot machine into a predictable production pipeline, essential for anyone shipping commercial assets on tight deadlines.
