YAML-Based

Human-readable definitions you can author by hand or generate with AI tools like Codex and Claude.

Tweak

Refine any asset with hand-crafted prompts, direct edits, or upload your own images.

Full Control

Pin assets you love, selectively regenerate the rest. Nothing changes unless you say so.

Rich Previews

Browse every generated asset at a glance — play back audio, video, and inspect images.

Karaoke Subtitles

Preview Movies

Watch your movie come together with full playback and live subtitle rendering.

Multi-Track Timeline

Inspect video, narration, and music tracks on a multi-track timeline you can scrub and interact with.

FAQ

Frequently asked questions

Everything you need to know about Renku.

Is Renku open source?

The core, providers, and compositions packages are MIT licensed. The other packages — including the website branding, CLI, UI, and desktop app — are source available.

Is Renku free?

Renku itself is free to use. Generating videos requires signing up with AI providers of your choice, who charge according to their own pricing plans. You enroll with them directly and supply the API keys you receive.

Can I use Renku on Windows?

Yes, but you need to enable WSL2 and run the Renku CLI inside a Linux shell.

Why do I need Renku?

Generating a compelling video longer than 10–20 seconds typically requires assembling shorter clips through many iterations, along with consistent images, audio, and model-specific prompts. Renku lets you define an orchestration pipeline and track dependencies between generated assets, so only what actually changed gets regenerated — saving time and cost as you iterate. It also helps you craft prompts, generate character images, and assemble everything into a multi-track timeline with video, narration, music, and subtitles. See the docs for more.

Can I use DaVinci Resolve, CapCut, or other tools alongside Renku?

Absolutely. Renku saves all generated media assets to a folder you can open directly in any video editing application.

Does Renku produce AI slop?

Renku is not a generative AI model. It helps you select and work with the best models for your use case, and gives you the controls to iterate and refine their output. The creative quality is in your hands.

Can I use Renku for long-form videos?

Renku is currently best tuned for videos in the 6–20 segment range, roughly under 5 minutes. There is no hard limit, so feel free to experiment with longer videos — your feedback helps us improve the experience.

Do I need to write YAML to create new blueprints?

YAML is the internal representation format, but you will rarely need to write it from scratch. We provide skills for AI tools like Claude and Codex that do an excellent job of generating the right YAML for your use case.
