[AG-TECH] BlackMagic HDMI vic beta download

Wed Feb 18 10:28:59 CST 2009

Gurcharan,

The only difference between the Intensity and Decklink cards format-wise is
that the Decklink cards support 24PsF, which I don't think vic is using -
all Blackmagic capture cards support 1080i50, 1080i60, 720p50 and 720p60. As
Changhyeok said vic currently only supports 1920x1080 at 25fps, presumably
meaning 1080i50, which is a PAL format.
