Luma AI's Dream Machine model modifies existing video by retransforming visual style while preserving motion. Through RunAPI, it shares unified API access and per-call billing.
A single RunAPI API key unlocks the whole model catalog across all providers. No separate accounts to create, no API keys to rotate per integration, and no credential management overhead. Add a new model to your app by changing one parameter.
Per-call pricing in USD, billed monthly into a single invoice. No subscription tiers, no minimum spend, and failed generations are never charged. The pricing page and check_pricing API show exact costs before you commit to a model.
Typed schemas, parameter constraints, and setup notes are packaged in the model skill so your implementation starts from the right contract. The skill loads into Claude Code, Codex, Gemini CLI, Cursor, and VS Code — your agent knows the correct request shape before you write a line of code.
Luma's modify-video endpoint takes existing footage and retransforms its visual style and content based on a text prompt, while preserving the original motion and camera dynamics.
Yes — camera movement, subject motion, and temporal structure from the source video are maintained. Only the visual style and appearance change.
Any style describable in text — cinematic, anime, painterly, noir, retro, futuristic, and more. The prompt controls the transformation direction.
MP4 is the primary supported format. Source clips should be within the size and duration limits specified in the API docs.
Both transform existing footage from prompts. Luma focuses on style transfer via the Dream Machine architecture. Runway Aleph emphasizes frame-level continuity preservation.
Pick the cheapest variant that meets your quality bar. Most teams start on the fast variant and graduate to pro for production.
