Runway Advanced tutorial

Advanced · step 1 of 7

Decompose and chain

1. Split a big job into steps with a clear output each.
2. Feed each step's output into the next.
3. Check the output between steps, not just at the end.

Why this step matters: Small steps with a checked output each fail visibly and early, instead of one big answer that is wrong somewhere.

Structured output

Ask for a fixed table or JSON so you can check and reuse it.

Return only JSON: [{"claim": "...", "source_url": "...", "quote": "...", "confidence": "high|medium|low"}]

Why this step matters: A fixed format can be checked by eye or by code and reused without retyping.

Automation and agents

Runway offers a developer API (see the official docs). Prototype prompts in the app first, then automate only proven shots, with a credit budget.

Why this step matters: Automation repeats mistakes at scale, so you need to know exactly what is run and what is checked.

Failure modes to watch

• Warped hands, faces and text.
• Inconsistent characters between shots. Use references.
• Physics that looks wrong in motion.

Why this step matters: Knowing how it typically fails tells you where to look when you review its work.

Cost control

• Free: 125 credits, one time.
• Standard: $12/month billed yearly ($15 monthly), 625 credits a month.
• Pro: $28/month yearly ($35 monthly), 2,250 credits.
• Max: $76/month yearly ($95 monthly), 9,500 credits.

Gen-4.5 uses 12 credits per second. Standard and Pro credits don’t roll over; Max rolls over one month. Purchased credits never expire (minimum 1,000) (runway.com/pricing, checked Oct 30, 2026).

Monthly credits by plan (625 / 2,250 / 9,500). Gen-4.5 costs 12 credits per second. Standard and Pro don’t roll over (runway.com/pricing).

Why this step matters: Paying for features you don't use is the most common waste. Knowing the limits first tells you if the free tier is enough.

Privacy and team rules

• Don't paste passwords, ID numbers, card numbers or other people's private details.
• Assume the company can read and keep your chats unless its official policy says otherwise.
• For health, money or legal decisions, confirm with a professional or an official source.
• Don’t generate realistic video of real people without consent.
• Label AI-generated video where your platform requires it.
• Write down which data is allowed in which tool, and who approves paid plans.

Why this step matters: Anything you paste may be stored and read. Deciding what never goes in is easier than undoing a leak.

Build a 10-task test set

1. Collect 10 real tasks with known good answers.
2. Run them now and score each pass/fail.
3. Re-run them when the model, plan or your prompt changes.
4. Keep the prompt that wins, not the one that feels better.

Why this step matters: Without a fixed test set, 'better' just means 'felt better'. Scores let you compare prompts and models fairly.
