One of the features that stands out for me in vMix29 is Open Media Transport (OMT), the license-free version of NDI. This makes it very easy to distribute video streams within a network with virtually no delay. Up to 4K or 120fps.
Apparently, Replay in this version should require up to 50% less CPU resources. * More shortcuts again, it's getting easier and easier to recreate any EVS situation * New Quad View Screen
