At work i've used many internal Blackmagic cards for video output to monitor, but i have no experience with their external devices. I have a new iMac 27" (top spec) in order and want a reliable video output for monitoring while editing and working with color corrections. Capturing is not an important feature, but i would like to have the possibility. The Intensity Extreme seems to have good compatibility with software. Better than the Shuttle it seems. Currently i use mostly FCP7 and Apple Color, but considering newer alternatives as both of these are aging. Maybe Davinci Resolve and FCPX. Haven't decided. Is the Intensity Extreme with thunderbolt a good choice, or is there other manufacturers in the same price range i should consider? Any with first hand experience with the device?
