The ATEM Production Studio Live 4K Switcher supports 4K Ultra HD video (3840 x 2160), which is four times the resolution of Full HD. It has eight video inputs, all of which can be active simultaneously.
The switcher features four single link 6G-SDI and four HDMI 4K inputs, which allows you to connect SD/HD/Ultra HD and computer-based signal to the switcher. Although the switcher takes reference video in for sync timing so that it can interface with other post production equipment, each input has its own Frame synchronizer, which enables you to use cameras that do not have genlock capability or for input of computer sources such as Keynote or PowerPoint Presentations.
The capture video format is set by the user, and must be the same across each input, as the switcher cannot scale different input formats to match the project format.
