I have a Sony CCD camera connected to a controller that outputs video as
analog RGB with external sync (four cable BNC). The video monitor (NTSC/PAL)
used to view the live feed has since died and I'm looking for an alternative
for video monitoring. I'd like to use a vga monitor (PC) as a replacement.
Not much luck yet finding a suitable conversion device or component.
Everything I've read seems to say it isn't that easy. Is it? Or could you
use a video card to capture the live video into a PC? A frame grabber would
work, but it makes focusing the camera difficult as you have to constantly
focus-grab, focus- grab. Best case would be a card that can handle real time
live feed. I'm asking for professional advice on options. Video card or
otherwise. Video conversion is not my specialty, so I wouldn't mind a
dummy's guide sort of approach. Thx.

No easy conversion because the scan rates are so much different.

Best to find a used RGB input video monitor to use or fix the old one.

The video capture cards do not even have RGB input but typically only
have composite or s-video inputs, some newer high end ones have
component input, but no RGB input.

Some of the earlier multi-sync VGA monitors that had the bnc
connections also would do the standard ntsc and pal frequencies, but
those are rare to find now.

Not worth it.

Because the scan rates are totally different, you would need a scaler.
These are not cheap, you would be better off spending the money on a new
monitor.
