1st of all, i own a Vmix HD edition and my usage for vmix have been purely just for playbacks of content and it work wonders for a windows user given it has all the foundation of what a playback tool should have. Cue by cue all spot on and giving countdown right the the exact time is perfect too. i wonder who is using vmix as a playback tool like how mac user utilize the well known PVP2 or playback pro as a playback tool. Before i try using it as a playback tool for widescreen given a 3213 x 1080 base on a native resolution of 1920 x 1080 projector with a blending of 627px. i am asking have anyone uses the 4k edition and try it out be it using a laptop which can output 2 full hd resolution or uses a matrox triple head to go to hit that number of px count. any experience will be taken in because if it works, i would like to upgrade my current version to a 4k edition as some client are just bloody acting poor to pay for some proper playback servers. Cheers! Fighting!
