ATEM Control is a control surface for an ATEM switcher on your network. Cut the program, mix the audio, and shade cameras from an iPhone that stays awake for the whole show. SWITCHER Choose Program or Preview, then cut or take an auto transition. Route a source to an auxiliary output. On a switcher with two mix effects, work ME1 and ME2 from the same panel. Eight source buttons follow the tally: red on program, green on preview, amber when a source is on both. Hold a button to assign a different input, and add a photo so you can find it in the dark. Media players, color generators, color bars, black, upstream keyers, and downstream keyers are on the same screen. AUDIO Faders for the switcher mixer, classic or Fairlight. Set each input Off, On, or audio-follow-video, and watch the meters while you ride the level. Master can follow fade to black. Mute the monitor. Headphones have their own level. CAMERA Shade Blackmagic cameras through the switcher: iris and auto iris, pedestal, gain, shutter, ND, white balance, and tint. Camera buttons use the same program and preview tally as the switcher. Lock the panel when the show is live. Tally stays visible, and the buttons stay put until you unlock. ATEM Control talks only to the switcher address you enter. It does not stream or record. It is an independent app and is not affiliated with Blackmagic Design. Requires an ATEM switcher on the same network. iPhone, iOS 15 or later.
