Not sure if the mods will delete this but I use vmix purely for their instant replay functionality. Mimolive is much further ahead in terms of graphics functionality, and SDI playout, so I just have my vmix replay as a camera source. Of course this means that you have to have a separate computer to run vmix and you have to pay for a vmix license so the cost does rack up.
Be careful what you wish for, replay recording takes up CPU and LOADS of disk space.
