AVMatrix 4K HDMI Real-time Chroma Key Master

AVMATRIX KM32-4K is a professional 4K HDMI chroma keyer with three inputs, four outputs, Smart Keying, DSK and PIP.

AVMATRIX KM32-4K is a standalone 4K HDMI chroma keyer for real-time green- or blue-screen compositing. Three HDMI inputs, four HDMI outputs, DSK and PIP make it a practical solution for virtual studios, streaming, education and live production.

Three 4K inputs for foreground, background and DSK

Dedicated inputs accept the keyed foreground, background and downstream-key source. The unit handles HDMI signals up to 4K and creates a finished composition without loading the production computer.

One-Touch Smart Keying

Automatic smart keying rapidly configures green- or blue-screen parameters and helps produce clean edges in challenging scenes. Manual adjustment is available from the front panel or PC software.

Four independent 4K HDMI outputs

PGM, Clean PGM, Matte and AUX outputs provide separate signals for broadcast, preview, key evaluation and additional equipment. External audio and tally inputs simplify multicamera coordination.
