Kona card
I’m not too familiar with Kona Cards….here is what I am trying to do.
I am trying to capture video from a PC. So I take the DVI cable, and plug that into a grass valley converter. That gives me SDI out, but for some reason (maybe the converter is broken?) I can only get 1080i 30 out of it….
Is there anyway to deinterlace on the way in with the Kona card, so the footage is progressive? I’ve tried calling grassvalley, but they aren’t helpful at all.
Thanks!

It’s the GVG that’s sending out the interlaced signal. You can’t de-interlace it with the Kona, but you can after you capture it. Just add a de-interlacing filter.
The device you are using is most likely something called a SCAN CONVERTER, and an old one. So the only option it has is Interlaced.

It has dip switch settings that indicate 1080p 30 which is ideally what I need.
Is there any quality loss if we capture 1080i 30 and make it progressive in post?

Actually, there is loss. Half of the resolution is discarded…half the fields tossed out. I know After Effects de-interlaces better.
So that dip switch isn’t working, huh?

if you blend the fields, you keep the resolution,
but will get ugly (to my eye) smearing on fast motion.for de-interlacing within FCP, i recommend the Graeme Nattress Smart De-interlace.
best there is, IMOnick
