Can I vibe code Runway?
AI video generation and editing — text to video, green screen.
Runway is a frontier model company wearing an editor UI. Text-to-video generation, motion brush, and their green-screen quality come from proprietary models trained on GPU-years of compute — there is nothing to vibe-code except a wrapper around someone else's video model API, at which point you've rebuilt the checkout page, not the product. If you want AI video, you're choosing whose models to rent, not whether to build.
Don't clone Runway — build a video-generation workbench over APIs instead. A Next.js app where I write prompts, pick a provider/model from a config file, queue generations, and see results in a gallery with the prompt, seed, and settings saved per clip. Support regenerate-with-tweaks, side-by-side comparison of two takes, favorites, and cost tracking per generation (log tokens/credits per provider). Store metadata in Postgres and videos in object storage. Design it so adding a new provider is one adapter file.
Realistically: a batch UI over a video-generation API (Runway's own, or open alternatives) that queues prompts and organizes outputs — a workflow tool, not a Runway.
- The models themselves — the entire product
- Frame-consistent editing tools (motion brush, inpainting)
- Professional export pipeline and team review features
- Every future model upgrade you'd get for the same subscription
The subscription is model access; the editor is a bonus. You cannot DIY a diffusion video model with an agent and a weekend.
A prompt is the first move, not the whole game. Course 01 teaches you to take a prompt like this one to a shipped, working app — reviewing, correcting, and steering the agent the whole way.
