Article Summary

Composer is a multi-purpose software for live video compositing, effects, and encoding.

Composer is an integrated & cost-effective solution that replaces components typical in a video set up for live online productions. Composer combines a video mixer, an audio mixer, a GPU-based engine for real-time video effects, a keyer, filters, and a video encoder into a generic software application designed for 24/7 operations. 

Compositor provides secure, web-based APIs:s for easy back-end integration and event-driven visualizations, and the runtime version of Composer has been created for large-scale setups. Use the Live Editor to design your project on your workstation and push your setup to hundreds of customers using the highly efficient Linux runtime edition designed for cloud deployment.

The integrated Chroma Keyer and the flexibility of Composer support setups using multiple cameras and multiple brandings/outputs on a single server instance. Below is a couple of examples:
