vMix 4K Live Production Software + Six Virtual Sets provides you with a 4096 x 2160, 1000-input, recording, streaming, and output solution plus six advanced virtual sets to enhance your production. vMix 4K is almost exactly like the full-featured vMix Pro software but supports only two remote guest callers (as opposed to 8) and features only one instant replay channel (instead of 4). The six virtual sets come as .xml files in 2880 x 1620 (2.5K) resolution, and allow for virtual pans and zooms, complete customization of the design, and replacement of select images with videos/images.
