More about the Switchblade VMC20 – Professional Broadcast Control Surface for vMix

The Switchblade VMC20 is a compact, feature-rich video switcher control panel designed to bring professional-grade switching capabilities to any live production environment. Compatible with both Blackmagic Design ATEM switchers and vMix live production software, the VMC20 offers unmatched flexibility for studios, mobile production trucks, and portable flypacks—anywhere space is at a premium.

Each channel features a crisp monochrome OLED display that clearly shows the channel name, making it easy to keep track of multiple inputs in fast-paced production settings.

A built-in 5.5-inch full-color display provides easy access to the system’s settings and configuration menus, while an ergonomic PTZ joystick and dedicated preset buttons give you smooth, precise control over pan-tilt-zoom cameras.
