Smelter

Intro

Smelter is a real-time video compositing toolkit created by Software Mansion. It targets low-latency multimedia composition for live streams and pre-recorded videos and is presented on the project site with a free trial option. The site also includes pricing information and privacy-related material, though detailed pricing tiers and full privacy practices are not shown in the provided snippets.

Key Features

• Combine multimedia from different sources into a single video or live stream.
• Enrich compositions with text, custom shaders, and embedded web content.
• TypeScript SDK that provides React components, hooks, and utility functions to control video composition.
• SDK offers different runtime variants designed to run Smelter in specific environments.
• Described on the site as offering ultra-low latency real-time composition; quantitative latency metrics are not included in the cited material.

Who this is for

• Developers building real-time video applications who will integrate via the TypeScript SDK and React components. Runtime variants mean integration and deployment may require attention to the environment you plan to run in.
• Live streamers and broadcasters who need to combine multiple media sources for live or pre-recorded video and want a toolkit focused on low-latency composition.

Practical notes: a free trial is offered on the site, but callers should expect to consult the Smelter documentation and contact the vendor for detailed pricing tiers, performance numbers, supported platforms, and full privacy or licensing terms.
