Blackmagic Design ATEM Television Studio 4K8 Blackmagic Design

Podrobný popis

ATEM Television Studio 4K8 is a live production switcher with a built-in broadcast control panel – a whole television studio in one portable desk for halls, clubs, schools and compact broadcast vans. It offers eight standards-converted 12G-SDI inputs up to Ultra HD 2160p60, ten 12G-SDI aux outputs, hardware streaming, recording of the program to USB disks, multiview, a 58-channel audio mixer, four ATEM Advanced Chroma Key, talkback and Blackmagic Cloud support.

An Ultra HD studio for eight cameras in one desk

ATEM Television Studio 4K8 combines a switcher, a broadcast control panel with T-bar, an audio mixer, multiview, streaming and recording in one unit that fits even where there is no room for racks.

A whole television studio in one unit

Switcher, control panel, audio mixer, talkback, multiview, streaming encoder and recorder in one chassis with built-in 100–240 V AC mains power and a backup 12 V DC input.

No racks or broadcast van needed

The desk fits into small clubs, halls and compact broadcast vans; for stability it can even be mounted inset into a desk.

Free ATEM Software Control

The Mac and Windows app gives access to every switcher feature; over Ethernet several computers can connect at the same time.

Broadcast panel with T-bar

The front panel uses the same buttons as large broadcast switchers: program and preview rows with LCD labels, a select bus for keyer and DVE sources, ten macro buttons, a T-bar for manual transitions, record and stream buttons and direct switching of two aux outputs. Audio control has its own LCD with level metering and rotary knobs, and a 3-axis joystick sits on the upper section of the panel.

Eight cameras without external sync

Each of the eight 12G-SDI inputs has its own standards converter and re-sync, so HD and Ultra HD sources up to 2160p60 can be mixed. Connect cameras with SDI outputs such as Blackmagic Studio Camera or Blackmagic URSA Broadcast G2, as well as recorders and other sources.

Program and preview like a large studio

A source is set up on the preview row and goes to air only with the CUT or AUTO button, so mistakes are caught before viewers see them; for volunteers a simpler A/B mode can be selected. Transitions include mix, dip to color, SMPTE wipes, DVE squeeze and push, graphic wipe and stinger.

DVE and SuperSource

The DVE creates picture in picture with borders, shadows and lighting in real time. SuperSource layers four extra DVEs over a media pool or live background into a separate input – perfect for interviews with several guests within one graphic.

Four ATEM Advanced Chroma Key and media pool

The ATEM Advanced Chroma Key keyers remove green or blue backgrounds; a color picker sets the parameters automatically and foreground correction matches the layers. Two media players with fill and key draw on a pool of 20 stills and clips of up to 1,600 frames in 720p, 800 in 1080p or 200 in 2160p for animations and stingers.

Audio mixer, MADI and talkback

The 58-channel mixer has separate channels for every SDI input and for the XLR, RCA and MADI inputs; each offers a 6-band parametric EQ, compressor, limiter, expander and noise gate and is controlled from the panel or ATEM Software Control. Talkback accepts a 5-pin headset and connects via RJ45 to systems such as ClearCom or RTS; MADI adds microphones with ATEM Microphone Converter.

16 sources on one monitor

The multiview on the SDI and HDMI outputs shows up to 16 windows in 16, 13, 10, 7 or 4 layouts – inputs, program, preview, media players and SuperSource with tally, labels and audio meters, in HD or Ultra HD. Status views track recording, streaming and the mixer.

Streaming and webcam

The built-in hardware encoder streams via RTMP to YouTube, Facebook or Twitch over Ethernet or through a 4G/5G phone connected to USB. USB-C appears to a computer as a 1080p webcam, so the program goes straight into Zoom, Teams or OBS.

Recording to USB disks

The program is recorded as H.264 MP4 with AAC audio, Ultra HD as H.265 to USB disks on the two USB-C ports or to optional internal M.2 memory; when one disk is full, recording continues on the next. It is started with buttons on the panel, its status shows in the multiview and recordings can sync via Blackmagic Cloud.

Built-in mains power and 12 V backup

The 100–240 V AC mains supply is built into the unit, so there is no external adapter to carry; the 4-pin XLR 12 V DC input serves as backup or for running from batteries. The electronics are modular – a technician can swap the connector board after removing the bottom cover.

Rear connections

The rear carries AC and 12 V DC power, reference, timecode and MADI on BNC, two USB-C ports, RS-422 remote control, RJ45 for external talkback, a 4-port 10G Ethernet switch, eight 12G-SDI inputs, twelve 12G-SDI outputs including ten aux, program and multiview, HDMI multiview, analog audio outputs, an RCA stereo input, two XLR inputs and 5-pin talkback.

Dimensions and weight

The desk measures 585.2 × 375.2 × 161.2 mm (the joystick rises a further 16 mm) and weighs 6.76 kg; it can stand on a desk or be mounted inset into the desk top.
