True Broadcast Style Mix Effects Switching

ATEM Constellation uses a professional "program/preview" style operation, which is the exact same way large broadcasters use live production switchers. This means you are using the same type of switcher used by the television industry. Both the free ATEM Software Control and the optional hardware ATEM Advanced Panels will allow program/preview style switching. This means you can select a source on the preview bus to ensure it’s correct before pushing the CUT or AUTO button to switch it on air. This 2 step program/preview process means far fewer mistakes! Program/preview operation means ATEM Constellation is the best solution for training students for a career in broadcast television!

Front Panel

Full Front Panel Control

With a control panel built into the front panel, you can simply walk up and operate the ATEM Constellation at any time. ATEM Constellation has similar features to ATEM Mini, so it’s a fantastic upgrade when you need a bigger switcher! Plus the front panel control buttons are the same premium type used on full sized panels so they are extremely reliable. You can even control keyers, media and fade to black from the front panel! There is an industry standard 5 pin talkback headset connector on the front panel, with controls for talkback control. Plus the front panel LCD and menu buttons also allow almost every single operational feature of the switcher to be accessed!

Up to 40 Standards Converted SDI Inputs!

The ATEM Constellation family features HD models that have up to 40 independent 3G-SDI inputs as well as 4K models with 12G-SDI inputs, with each input featuring its own dedicated up and cross converter. That means it’s possible to convert any 1080p input source to the video standard of the switcher! That means you could have each switcher SDI input running a different television standard and all the inputs will just work! On the ATEM 4 M/E Constellation models, you can even loop out audio channels 1, 2, 3 and 4 from SDI inputs 1 to 30 to the two MADI digital audio outputs, so you can hand off the switcher input audio to an external audio engineer for mixing.

Up to 24 Customizable SDI Outputs

The ATEM Constellation family has a massive number of fully independent outputs. Even the small 1 M/E models have 6 outputs! The 2 M/E models have 12 outputs and the 4 M/E models have a massive 24 outputs. These SDI outputs are very powerful because you can independently route any SDI input or any internal source to each SDI output. That’s perfect for running independent feeds to stage screens, master recorders and streaming processors. Or use the SDI outputs for ISO recorders, where each deck will get a resynchronized switcher input with matching timecode. All SDI outputs contain program audio, RP-188 timecode, SDI camera control, tally and talkback.

USB Webcam Output for Video Software

For live streaming, the USB-C connection on ATEM Constellation operates as a webcam source. That means you can plug into a computer and get working with any video software! The software is tricked into thinking the ATEM Constellation is a common webcam, but it's really a live production switcher! That guarantees full compatibility with any video software in full resolution 1080HD quality. Choose any software you like, such as Zoom, Microsoft Teams or Skype for a new way to do presentations with a professional multi camera broadcast quality style! The ATEM Constellation webcam output also works with streaming software such as Open Broadcaster, XSplit Broadcaster and more!

Hardware or Software

Choose from Hardware or Software Control Panels

All ATEM switchers feature a wide range of hardware and software control options, plus it’s possible to share control panels between all ATEM models for different events. Included with ATEM Constellation is a free software based control panel for Mac and Windows. The software connects to the switcher via Ethernet or USB and you can control the switcher, upload media, mix audio and control cameras. Then, when you need more power, you can add an ATEM Advanced Panel for professional switching or an ATEM Camera Control Panel for controlling cameras. There's even an ATEM developer SDK so you can build your own custom automation control solution!

The 1 M/E models include 1 multiview, the 2 M/E models have 2 independent multiviews and the 4 M/E models have 4 independent multiviews! All external SDI inputs, plus all internal video sources can be routed to any view. All multiviews are fully customizable and can be independently set to 4, 7, 10, 13 or 16 simultaneous views. That’s up to 32 views in total on the 2 M/E models and a massive 64 views across 4 monitors with the 4 M/E models! You can add the tally border plus source label and VU meters as an overlay on each view. Plus a red and green border will show tally on each view, so you know what sources are on air.

ATEM 4 M/E Constellation HD features 4 HD multiview outputs so you can see up to 64 different views from cameras, program and preview outputs, and more spread across 4 screens!

Broadcast Transitions, DVE, Stingers and More!

ATEM Constellation includes a wide range of broadcast quality native transitions such as mix, dip, wipe, and more. All transitions can be customized in the system control menus with adjustments for border color, border width, position, direction and a lot more! The ATEM Constellation switcher includes a powerful digital video effects processor for DVE transitions, which can be used to squeeze the current picture off screen revealing a new video under it. The DVE can even be used to create graphic wipe transitions. To eliminate errors, ATEM Constellation features a preview transition feature so you can setup your transitions before you switch it on air!

Built in DVE for Video Effects

ATEM Constellation features up to 4 independent DVEs, depending on the model, that let you reposition graphics and create picture in picture compositions. You get amazing quality and the DVE supports position, resize and scale, all in real time. The DVE lets you create professional picture in picture effects with customizable 3D borders, shadows and lighting. DVEs can also be used to create amazing DVE transitions with squeeze and swoosh effects for adding excitement to your programming. You can even combine DVE transitions with custom graphics to create your own graphic wipe transitions! Then the 2 and 4 M/E models include SuperSource processors for even more DVEs!

8K DVE

Professional Broadcast Talkback

To keep crews working as a single creative team, ATEM Constellation features built in talkback. Talkback supports a 5 pin XLR headset connector, plus a rear mounted RJ12 connector for interfacing with industry standard talkback systems such as ClearCom or RTS. You get full talkback control including program and engineering loops, sidetone control for hearing the headset mic into the headphones and program mix. ATEM Constellation also supports SDI talkback that uses SDI channels 15 and 16 for 2-way communication with Blackmagic Design cameras. You can even use channels 13 and 14 for engineering talkback. It’s even possible to mix the talkback mic into the program audio for voiceovers!

Talkback

Internal Media for Stills and Motion Graphics

The built in media pool stores broadcast quality RGBA graphics and animations that can be played back instantly by the 2 or 4 media players. Media players simply appear as additional input sources on the ATEM Constellation, so you don’t have to use extra SDI inputs for graphics. The built in media pool holds graphics for use with the media players and the 1 M/E models can hold 20 stills and 200 frame animations, the 2 M/E models can hold 40 stills and 400 frame animations and the 4 M/E models can hold 60 stills and up to 400 frame animations. You can easily manage all of your media using the included ATEM Software Control or download directly from Photoshop using the ATEM Photoshop plug-in.

Media Panel
Advanced Chroma

Includes New ATEM Advanced Chroma Key!

For news or virtual set work, ATEM Constellation is perfect as it features lots of ATEM advanced keyers for high quality chroma or luminance keying! The chroma keyer is incredibly powerful and features a color picker to sample background colors for automatic generation of the key parameters. You get precise controls for edge and flare, and there is even a foreground color corrector so you can match the "look" of the foreground layer to the background layer making seamless compositions possible. The keyer can also be used for pattern and DVE keying! You get 4 ATEM Advanced Keyers on the 1 M/E models, 8 ATEM Advanced Keyers on the 2 M/E models and 16 ATEM Advanced Keyers on the 4 M/E models.

Live Broadcast, Television and Film Production Create Amazing Virtual Sets

Create Amazing Virtual Sets

With 4 upstream chroma keyers per M/E row, you get the perfect solution for building virtual sets! With so many ATEM advanced chroma keyers, you can use a keyer per camera to create a seamless composition of the camera over the custom background. Even the 1 M/E models have enough keyers to generate a 4 camera virtual set! You can use external image processors for virtual sets, or you can even build a fixed camera virtual set by loading pre rendered still image backgrounds from the media players and media pool. You can setup macros to change cameras and load the correct background into the media players! With so much flexibility, you can experiment to try out different studio setups!

Powerful SuperSource Processing!

Powerful SuperSource Processing!

In addition to the DVEs in the M/E rows, the 2 M/E and 4 M/E models include powerful SuperSource multi layer processors with 4 extra DVE layers plus a background layer, that all appear to ATEM Constellation as an additional input source. Any switcher video input can be used for each SuperSource DVE, then it’s all layered together over a media pool custom background. SuperSource is just like having an extra multi-layer VFX switcher built in! SuperSource is perfect for doing picture in picture displays for interviews because you can set up the effect while keeping the main DVEs free for other tasks. The ATEM 4 M/E Constellation models even have 2 completely independent SuperSource processors!

Multi Rate SDI for HD and Ultra HD Video Standards

Multi Rate 12G-SDI for HD Video Standards

With up to 40 multi rate SDI input connections, depending on the model, the ATEM Constellation is compatible with all types of video sources. You can connect equipment in HD or Ultra HD television standards including 720p, 1080i,1080p and 2160p formats. Only multi rate SDI allows switching between formats so you can instantly adapt to the needs of the job you are doing anywhere in the world! The SDI inputs will also handle embedded audio and mix audio from all video inputs. The program outputs include talkback, tally and camera control information. So you can connect any of the switcher SDI outputs back to the camera for program return, camera control, and talkback.

The First Switcher with Big Professional Audio

The First Switcher with Truly Professional Audio

ATEM Constellation is the world’s first live production switcher that fully embraces live professional audio production! All SDI inputs are connected to a built in Fairlight audio mixer that features 6 band parametric EQ, compressor, limiter, noise gate and expander on each input. On the ATEM 4 M/E Constellation models there are 2 MADI outputs for breaking out channels 1, 2, 3 and 4 of the first 30 SDI inputs out to an external audio engineer, plus a MADI input for allowing an extra 32 external audio channels in to the audio mixer.
