What is Smelter?
Smelter is a comprehensive video compositing solution designed for real-time multimedia processing. It provides ultra-low latency composition capabilities that allow users to seamlessly mix live feeds, screen recordings, and pre-recorded videos into a single output. The platform supports dynamic overlays including text, animations, transitions, and graphics that can be applied to both live and recorded content.
