At the same time, there is a 12 channel audio mixing capability that can use HDMI, microphone and standard stereo inputs. I have not used it in a real-world situation, but the two-knob system seem quite efficient and intuitive. It is also possible to control it over USB or MIDI (PC/Mac/iPad), in case you find apps that are compatible with this mixer. There are 2 HDMI outputs used for recording and visual control simultaneously.
Honestly, I would not do all the editing on this, but it could be very handy for real-time effects such as the green screen. For live events, it may be easier to handle if the video setup is simple enough. At around $1000, it could also be used in a semi-pro setting such as professional presentations switches, etc… once you know its capabilities… your imagination is the limit.
