Introduction
Runway is a Video Studio provider — it drives AI video generation with strong character/product consistency and a cinematic, VFX-leaning toolset. It does not power copy or image generation; use other providers for those. This guide walks you through getting a Runway key, adding it in MagicAds, and the model it unlocks.How keys are stored
All AI provider keys live in the AI Settings screen and are stored encrypted in the database. There are no.env edits — keys are injected into the drivers at runtime. Users never supply their own key; every generation runs on the admin’s key.
A model only becomes available to users when both are true: the Runway API key is saved and the model is enabled in the vendor modal.
Before you start
- Admin access to your MagicAds platform.
- A Runway account with developer/API access and billing/credits.
Part 1 — Get your Runway API key
Open the Runway developer portal
Go to the Runway developer portal and sign in. This is the developer/API portal, separate from the main Runway app. New accounts include some free starter credits.
Add credits (prepaid)
Open Manage → Billing in the left sidebar and add credits. Runway’s API is prepaid — a minimum top-up (around $10) is required before the API will run. Runway charges you directly for usage — separate from your MagicAds platform credits.
API keys are organization-scoped, not user-scoped — every key belongs to your organization’s credit balance.
Part 2 — Add the key in MagicAds
Paste the key
Paste your API key into the API key field. Leaving it blank keeps the existing key unchanged.
Enable the model
Toggle on Runway Gen-4 Turbo and set its credit cost (what a user is charged per generation).
There is no “test connection” button. To verify, enable the model and run a quick generation in the Video Studio.
Part 3 — Supported models
Video Studio
| Model | Model ID | Tier | Default credits | Durations | Audio | Best for |
|---|---|---|---|---|---|---|
| Runway Gen-4 Turbo | gen4_turbo | Premium | 10 | 5s, 10s | No | Strongest character + product consistency across shots, with the best VFX/editing toolset. Best for UGC, handheld, and brand films. Supports image-to-video. |
The credit cost shown is the seeded default. You can change it in the vendor modal. It’s what your platform charges users in credits — not Runway’s price.
Part 4 — Make Runway the default video model (optional)
In the global section of AI Settings you can set the default video model to Runway Gen-4 Turbo so it’s pre-selected for users. You can also toggle the Video Studio on/off and control free-tier access there.Troubleshooting
| Symptom | Likely cause | Fix |
|---|---|---|
| Runway doesn’t appear in Video Studio | Key missing or model disabled | Add the key in the Runway vendor modal and enable Gen-4 Turbo, then Save. |
| ”The payload is invalid.” on generate | Saved key can’t be decrypted (e.g. after an environment change) | Re-enter the key in AI Settings and Save to refresh it. |
| Runway API errors / 401 | Invalid key or no billing | Re-check the key and billing in the Runway developer portal. |
| Video has no sound | Gen-4 Turbo has no native audio | Use a Veo (Gemini) or fal.ai (Kling/Seedance) engine for native audio. |
| Looking for Runway copy/image | Not supported | Runway is video-only here; use another provider for copy or image. |
Keys are stored encrypted and applied at runtime. No
.env changes or commands are needed after saving.
