Prompt lab
One Product, Five Prompt Styles
A reproducible comparison of how factual, editorial, energetic, minimal, and proof-led briefs change the planned video structure.
One Product, Five Prompt Styles
Hypothesis
The same product facts produce different scene emphasis when the brief changes the creative objective, even when the template family stays stable.
Test setup
Use the same linen overshirt, €79 verified price, breathable fabric proof, and 15-second vertical format. Change only the brief style: factual catalog, editorial, energetic sale, minimal luxury, and proof-led comparison.
Prompt/input
Run the five briefs through the product generator. Keep the input media and duration constant. Do not send customer data or private campaign identifiers.
Planner/template version
Prompt planner v1, generator contract verified on 2026-08-05, product launch template family. The output is a storyboard preview; this lab does not claim five paid MP4 renders.
Outputs and result comparison
Compare hook wording, number of proof beats, copy density, CTA prominence, and missing-asset warnings. The expected result is a shift in emphasis, not a guarantee that the planner chooses a different template.
Failure analysis
If the five outputs become indistinguishable, the prompts are not changing a meaningful production constraint. If one version invents a claim, stop the comparison and tighten the factual boundary before any render.
