The science of running

Integrations & settings

Connect the tools behind your creative workflow. Secrets never belong in the browser.

Secure backend status

Studio editing is open. Paid server actions require the app owner account.

Runway Gen-4.5 · official API

Paid · provider credits
Setup needed

Real text-to-video clips in 9:16 or 16:9, with 5 or 10 second scenes. Character continuity is prompt-guided, not a guarantee.

Server Secrets

RUNWAY_API_KEY

Built-in AI scene planning

GenMB AI
Setup needed

Structured AI scene planning uses the platform’s built-in AI. Sign in as the app owner to use AI storyboarding; the local storyboard builder remains available when signed out.

Server Secrets

No vendor API key required

OpenAI narration

Paid · usage-based
Setup needed

Synthetic scene narration uses the speech API. A server-side OpenAI key is required for narration only, not for AI scene planning.

Server Secrets

OPENAI_API_KEY

YouTube channel

Google OAuth · API quotas
Setup needed

Official authorization-code OAuth and resumable uploads. Enable YouTube Data API v3, configure consent and test users, and use the published app URL as the exact redirect URI.

Server Secrets

GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_REDIRECT_URI

One-time security setup

Enable Functions and Authentication in Add-ons. Add a strong random STUDIO_TOKEN_SECRET (at least 32 characters) in server Secrets. This encrypts account-bound OAuth credentials and signs generation task handles. Tokens can only be decrypted in server functions. Google access and refresh tokens are never exposed as plain text to the browser.

Project metadata uses the built-in user-scoped key-value store when enabled; otherwise it stays in this browser. Imported media stays in this device’s IndexedDB. Local media does not sync between devices.

Appearance

Cinematic dark, or a lighter editing workspace.

Honest capability limits

  • 720p is the native generation target; 1080p export is local upscaling, not native extra detail.
  • Export normalizes clips to 24 fps. No 4K, 8K, or 60 fps generation is claimed.
  • No automatic lip synchronization, word-level caption alignment, or AI-generated music / effects in this build.
  • Original licensed background audio can be imported. Review AI anatomy for accuracy.
  • Large local MP4 exports need memory; desktop browsers are recommended.
  • Configured does not mean tested. Make a short paid render and a private YouTube upload before production use.
