Hi John,
Interesting... Does anyone know anything about SDI HD capture
cards. We are looking at HD as well (but no direct experience yet)
and the trick seems to be to get video off of the camera avoiding
the onboard encoding of the video, which often adds significant
latency (which is not good for AG of course). Does anyone know if
the SDI out of this camera either has onboard hardware encoding (so
low latency) and/or whether the SDI out is uncompressed video (I
don't know anything about SDI other than that it is a broadcast
oriented standard). Since this is a video conferencing camera one
would assume the SDI is raw video (it looks like it base on my
reading). So once one gets it out of the camera how does one get it
to the computer... There must be an HD SDI capture card available.
We are looking at the Sony HDR-HC7 prosumer HD camcorder as a
possibility. They aren't available yet, but any day now... They
have HDMI out, which is uncompressed video. There is a HDMI capture
card that can handle raw uncompressed HD video at 1080i available
from Black Magic that looks promising... The camera is around $1500
and the card is $250.

We are going to be purchasing this pair as soon as the camera is
available, so I will let everyone know how this works out. If it
does work its a pretty inexpensive HD solution!
Cheers,
Brian

Anyone have any experience with it? I'm wondering if it was used,
how to best "capture" it into a system for use on the AG...
interest in using HD is high here. I'm more concerned about
logistical issues with high resolution images on displays that
don't have that much "resolution" space - particularly if several
sites are involved.
