We are a rental and staging company that just purchased our first two Ki Pro's. I have a few questions I hope someone can answer.

First, when I attempt to record via DVI to HDMI, I can never seem to get this to work. I'm out-putting 1280x720p59.94 via a Barco ScreenPro II. Is DVI to HDMI not supported?

Am I correct that the composite signal only works when down conversion is selected on component out? If so, isn't it a little silly to not always have it down convert since it's composite?

Does anyone else have issues getting certain pieces of equipment to "lock up" certain peices of gear? It seems that the tolerance for record is very high. I've had HDMI not stay "locked" when recording from a DVD. It seems very picky about its sources. Anyone else seen this?

Thanks in advance.

Mike

[Mike Evans] "First, when I attempt to record via DVI to HDMI, I can never seem to get this to work."

AJA's HDMI only supports SMPTE Video signals, while the HDMI protocol supports computer monitor and video display resolutions, AJA's tools only support the Video rasters. AJA also abides to ALL HDCP security measures- so you cannot record HDMI from set-top boxes or gaming consoles.

"Am I correct that the composite signal only works when down conversion is selected on component out? If so, isn't it a little silly to not always have it down convert since it's composite? "

No the composite out should work all the time.

"Does anyone else have issues getting certain pieces of equipment to "lock up" certain peices of gear? It seems that the tolerance for record is very high. I've had HDMI not stay "locked" when recording from a DVD"

I do not know what you mean by locked? there is no ancillary data stream with HDMI capture so device control is and should be manually controlled at the player device- ALSO see note above.

hi,

i think the ki pro want a component YUV signal to its input, and you're probably have a dvi device which uses RGB.
i have the same problem, you can solve it by using a blackmagic dvi extender, it converts dvi to hdsdi

I tried the DVI Extender. No luck. The Barco Screen Pro II would work at 1280x720P 59.94 but the colors were off/ People looked like smurfs. Blue and red color bars were reversed. They need to add 60 Hz as a resolution it can "see" and 1080P.
