Ultra HD Power of the ATEM Range, in a Desktop Chassis
Designed in the tradition of ATEM control rooms, the ATEM Television Studio 4K8 combines a broadcast control panel and 12G-SDI electronics. It delivers 2160p60 live production, a 4-port 10G Ethernet switch, internal/USB-C recording, and a generous MADI audio workflow. Compared to HD models, it extends Ultra HD support and HEVC H.265 codec for efficient 4K masters.
Ideal for Mobile Control Rooms, Corporate Studios, and Event Captures
Designed for teams needing rapid deployment and broadcast-quality production, the 4K8 covers multi-camera, simultaneous streaming, and master recording. Its 10 AUX outputs drive LED walls, stage monitors, and recorders, while the dual USB-C webcam outputs simplify hybrid workflows and videoconferencing.
Key Features for 4K Live Production
12G-SDI Connectivity and Versatile Routing
Eight auto-detected 12G-SDI inputs with synchronization, format and frame rate conversion, plus 10 12G-SDI AUX outputs and one program output. An HDMI 2.0 output and a dedicated 12G-SDI Multi View output complete the control display.
Reliable Streaming, Recording, and Masters
Stream live via Ethernet or USB-C sharing in RTMP and capture in .mp4 H.264 (HD) or HEVC H.265 (Ultra HD) on optional internal M.2 or USB-C drives. Two USB-C ports also provide webcam output for conferencing platforms.
Graphics, Keying, and Layouts
Four advanced chroma keyers, 2 DVEs, a Stinger, SuperSource, and two media players with fill/key enable titles, clean keyers, and multi-source compositions, all monitored on configurable Multi View.
MADI Audio and Integrated Mixing
With 32/64-channel MADI inputs/outputs and a 58-channel mixer featuring 6-band EQ, compressor, gate, limiter, and A-F-V, you maintain precise control over SDI, analog, and intercom sources.
Network and Control
The built-in 10G Ethernet switch (4 ports) facilitates software control, Cloud sync, and teamwork. RS-422 support, mix-minus, tally via optional GPI/Tally interface, and Blackmagic Design camera control complete the ecosystem.
