Lumantek ez-Pro VS4 4x1 Multiview Video Switcher

The Lumantek ez-Pro VS4 is a compact seamless switcher that mixes four sources across 3G-SDI and HDMI for live events, worship, and small studio work. Three HDMI inputs, one SDI input, and one interchangeable HDMI/SDI input feed the switcher, and it processes up to Full HD 1080p60 with 8/10-bit 4:2:2 color and both Level A and Level B 3G-SDI. The program is output over HDMI or SDI, and a separate HDMI multiview shows every source at once for confidence monitoring.

Beyond straight cuts, it handles an adjustable picture-in-picture, chroma and luma keying, and dual-logo insertion, so lower thirds and branding go on air without a separate keyer. Up to four channels of embedded audio are supported alongside external audio on stereo RCA inputs, with embedded-audio volume control on board. It is small and quiet enough to sit on a desk next to the operator.
