Blackmagic Design ATEM Television Studio 4K8 – 8-Input 4K Live Switcher

Product Overview

The Blackmagic Design ATEM Television Studio 4K8 is an all-in-one live production switcher built into a broadcast control panel, designed for television studios, remote production, and live venues. It combines eight 12G-SDI inputs supporting up to UHD 4K60, built-in hardware streaming, a 58-channel Fairlight audio mixer, four Advanced Chroma Keyers, and internal recording into a single portable unit.

Product Description

The ATEM Television Studio 4K8 gives you a complete broadcast-grade switcher with program and two aux outputs, professional camera control, talkback, and audio mixing in a familiar broadcast panel layout. Each of the eight 12G-SDI inputs has its own dedicated standards converter, so sources running at different video standards re-sync to the switcher automatically. The built-in hardware streaming engine sends live H.264 streams with AAC audio over RTMP, and you can record program output to USB disks or an optional internal M.2 drive, with files shared over the local network for editing while you record.

Production control is handled from the redesigned front panel — program/preview rows, a T-bar for manual transitions, a three-axis joystick, and a dedicated audio mixer area with live LCD metering — or from the free ATEM Software Control app on macOS and Windows. Creative tools include four Advanced Chroma Keyers, two downstream keyers, a SuperSource multi-layer processor, DVE effects, two media players, and a wide range of SMPTE wipes and transitions. Blackmagic Cloud integration makes program recordings available from anywhere, and the unit ships with both AC and 12V XLR DC power inputs for redundancy or battery operation.
