If you go with vMix for the IMAG solution I would definitely use the Magewell capture cards and output your signal in 60p. The faster frame rate cuts down your latency because vMix is able to send out a frame after a 60th of a second instead of a 30th of a second. Also send the native resolution to your screen to cut down any latency with scaling. We have been doing IMAG with vMix in our church for probably 4 years. The video below is an older video with a hair more latency than we have now. Are you still using vMix for IMAG? Is your latency still the same or has it improved? What hardware do you run vMix on?

My experience is that the Atem is not the perfect device for this, but the latency is totally OK.
But you should use vMix only as a graphics processor and output the graphix over a transparent background with a blackmagic decklink duo or ultrastudio mini card as cut&fill output. This works quite good for lower thirds etc.
If you want to have a professional thing, use analog way equipment or barco.

For simple talk shows the workflow camera hdmi/sdi out-->decklink hdmi/sdi in-->vmix and the vmix-->fullscreen out-->gpu-->tv monitor in the talents room, the latency is acceptable. For more professional things,more professional and expensive equiqment is needed
