Complete control of your Transitions
Control your Mix, Wipe, Dip, DVE and Stingers fast
ATEM Switchers are designed to give you fast and flexible control during live production operation. The transition control block lets you quickly select your transition style, you can choose between mix, dip, wipe or even DVE and animated stingers if you are using a ATEM 1 M/E Production Studio 4K. Simply push the cut button for an immediate transition, or select timed automatic transitions that are triggered by pushing the AUTO button. You also get full manual control with the fader bar!
ATEM gives you precise transitions adjustments! The switcher palettes are on the right side of the switcher control and are fast and logical to use. When you open the transition palette you can see every adjustable option for each type of transition. Simply choose the transition type and you can adjust all the individual parameters. You get so many options you will always find the perfect style for your production as there is almost no limit to the creative transitions you can create!
Create over 100 different styles from the 18 built in wipe pattens. Using the ATEM Software control transition palette, you can select your ideal wipe pattern, change its symmetry or even invert it! Wipe patterns can be softened or have colored borders with customizable width and softness. You can even feed live video inside a wipe border creating interesting geometric patterns with three live video streams at the same time.

The transition palette gives you precise control over the multiple DVE transition options. Choose from over 35 dramatic DVE moves that will bring an extra level of excitement to your production. DVE transitions can be flipped and reversed giving you even more creative options.
On Air, Select keyers on air live!
Once your upstream settings are customized, the fastest way to bring them on air is to use the ON AIR button! The on air buttons enable or disable the key signal, plus they also indicate which keys are live on air. When you’re switching live it's vital to know which keyers are active so you can select it as part of the next transition. Each upstream keyer has its own dedicated on air button so you will get 1 on the ATEM Production Studio 4K and 4 on the advanced ATEM 1 M/E Production Studio 4K model.
Keyer Control, Get perfect multi layering
When you need fast, precision keying you can use the software controls to adjust keying with high accuracy. Key backgrounds are never perfectly flat, so it’s important to have easily adjustable controls that let you quickly and precisely fine tune your key settings in real time for the best quality live broadcast results. The ATEM Software Control gives you precise control over every key parameter and you can use your mouse or trackpad to quickly adjust keys for the perfect result.
Fader Bar, Get full manual control
The most experienced vision switchers know that sometimes the only way to get a dramatic multi camera mix during live performances is with manual fader control! Automatic transitions are smooth but often do not have the subtlety needed when mixing between wide and close up angles of performances like music performances. With manual control you can mix shots together and hold the mix until the right moment before completing the transition. The fader bar also gives you manual control of wipe, key and even DVE transitions.
Auto Transition, Simply perfect transitions!
Smooth automatic transitions are easy with the auto transition button. Simply set your preferred transition rate between 1 and 250 frames using the ATEM software control, and every time you hit the AUTO button your ATEM Production Studio 4K switcher will perform a perfectly timed, smooth transition. You can use auto transitions for every part of the ATEM switcher including dissolves, dip, mix, fading on key sources, wipes and animated DVE transitions.
Preview Transition, Check your transitions
The PREV TRANS button lets you rehearse and preview complicated transitions before you take them on air! Your ATEM Production Studio preview video can be seen on your multi view screen or on a monitor connected to the switchers SDI preview output. Preview transition lets you verify the most complicated transition with mix, dip, wipe, DVE and even keys without affecting your program output. Preview transitions is the best way to ensure your transition is perfect before going to air.
Fade to Black, The perfect program end!
Ideal for the start and end of your production or fading down for commercial breaks, fade to black (FTB) is the absolute last layer of the switcher and ensures all the layers are faded down together. Once the program output has been faded to black, the FTB button will flash red until it is pressed again. Selecting fade to black again will then fade up from black at the same rate. With a dedicated fade to black button, you can be sure all sources are faded cleanly in sync for the perfect program end!
Full Audio Mixer, Control levels, balance and more!
The built in multi channel audio mixer lets you adjust the level and balance of the audio from each switcher input, plus the additional HiFi and balanced audio input connections. Each audio input is metered so you can always see the levels of each source accurately. You can set the audio to auto fade up and down as the switcher sources are changed and the mixed audio is then embedded into all video outputs!
Switcher Snapshot, Save the switcher state!
No matter how complicated your switcher set up is, you can quickly save it to your computer for fast recall any time you need it. Save complete or partial switcher setups as time stamped XML files so you'll never accidentally overwrite a saved setup. Save switcher positions, keys, wipes, DVE moves and even your entire media pool content! Any updated media is added to the media folder and mapped to the latest XML as you keep saving. Thats perfect for moving your job setup between ATEM switchers.
Media, Simple drag and drop media download!
ATEM features easy download of all your RGBA graphics and clips. From the software control media tab you can manage the built in media pool and see the status of each loaded graphic. You can drag and drop frames into the media pool spaces and they will automatically download to the switcher. You can also download graphics direct from the included Adobe Photoshop plug in!
