helios-core

What problem does it solve?

The Helios core API provides a high-level interface to create and control video compositions, manage timelines, and synchronize DOM-driven animations in a headless or live environment.

Core Features & Use Cases

• Timeline management: Create tracks and clips, control duration, and synchronize playback across frames.
• Playback and state: Start, pause, seek, and observe state changes via subscriptions.
• Studio / Renderer integration: Bind Helios to external renderers or document timelines for synchronized output.

Quick Start

Install and import the Helios core package, then instantiate Helios with a basic configuration and subscribe to state updates. Example: const helios = new Helios({ duration: 10, fps: 30, width: 1920, height: 1080 }); const unsubscribe = helios.subscribe((state) => console.log(state.currentFrame)); helios.play();
