i have a sony v1p-
http://bssc.sel.sony.com/Broadcastan...V1U/index.html
it has progressive scan at 25/30 fps - so no deinterlacing required-
i can use a hdmi cable to plug the camera directly into a decklink intensity card and get 1080p input with low latency-

latency seems much better with decklink intensity hdmi rather than decklink extreme etc. i think decklink updated their drivers for this card- they seem to work much better.
