When to use this prompt

Runway shines at marketing work when you state the observable outcome: one hypothesis. The Starter framing keeps first successful run with safe defaults visible while you edit. Bookmark this page if you run a/b test plan weekly.

Why this prompt works

Centers one hypothesis so success is observable.
Locks the audience (experimenters) before style so tone stays honest.
Asks for a self-check pass, which cuts hallucinated details.
Separates draft from critique so you can steal the structure later.
Forces an output contract: headings, examples, and a final version.

How to use it in Runway

Generate two seeds or takes, then pick the clearer silhouette or motion. Use plain and encouraging follow-ups only — mixing tones mid-thread confuses Runway models. Paste the prompt into Runway and replace bracketed details with your facts. Campaigns, positioning, and conversion copy. Keep that context in the thread when you iterate. Name the success metric aloud: one hypothesis. If the draft cannot pass it, do not polish prose yet.

Swap the audience once. If the a/b test plan piece still works, the core is solid. For a/b test plan in marketing, the failure mode is usually missing constraint. This prompt blocks that by design — especially "sample and metric". Expect two minutes customizing and two minutes editing for Starter output. Runway models still need your facts for a/b test plan; they cannot invent metrics or brand rules. growth and brand marketers teams bookmark slug ab-test-plan-starter when first successful run with safe defaults matters.

Step-by-step

Open Runway and paste the prompt block unchanged.
Replace placeholders with your project facts (experimenters, offer, timeline).
Confirm the constraint is still visible: sample and metric.
If output is vague, ask Runway to restate assumptions as questions first.
Reply with one fix list, then regenerate the final version only.

Example output

Example clip brief: 6s a/b test plan shot, motivated light, single camera move, subject action matches "one hypothesis", no wardrobe changes mid-clip.

Common mistakes

Asking for a/b test plan plus three other jobs in one message.
Deleting "sample and metric" to save space — that is usually the whole point.
Using the Starter prompt but editing it into a vague one-liner.

Expert notes

Runway users working on a/b test plan in marketing should treat "sample and metric" as non-negotiable. Campaigns, positioning, and conversion copy. When experimenters run the Starter variant, they usually care about first successful run with safe defaults more than length.

If video output feels generic, re-paste sample and metric as the first follow-up message — do not rewrite the whole prompt.
