vMix Pro is the complete edition of vMix, containing every feature in the program, and it runs on a Windows PC. It lets you simultaneously display, record and live-stream a production from a single machine, and it supports up to DCI and UHD 4K resolutions (4096x2160) for sharp imagery. Up to 1000 inputs are available and every input can carry a camera or NDI source, so the software is completely scalable from a single-operator setup through to a broadcast-grade production. Exclusive to the Pro edition is instant replay on up to eight cameras: the camera feeds are recorded in vMix AVI 4:2:2, with resolution support up to 4K, and can be played back in real time or with time manipulation. Alongside effects, transitions and virtual sets, it supports four External Outputs, two Fullscreen Outputs, four Virtual Outputs and PTZ control.
