Even with proper SONY vision switchers, we still end up keying with a CORIOGen or something like it. It's simpler that way, and you can always bypass the unit if the PC goes haywire.

If you end up getting a CORIOgen / TVOne Eclipse, you can download free PC software to control it here.

I'm looking to buy an outboard keyer. One for chroma keying a camera over both PC and video sources. And another two for keying PC graphics over video.

Anyone actually using any TVOne keyers that can speak to the quality of the product and video? Both the low end or the Corio based ones?
Like the:
AVT-3170
CS-450
CS-460
1T-C2-150

How about any users of the DataVideo units:
TBC-6000
TBC-7000
DVK-100

Thanks in advance,

Ben

We use a C2-150 and are very pleased with it. We use it to key lyrics over live video. We have the lyrics set for white text over black and have an off black shadow added to the text for readability, works great. I believe it took me about 2 hours of adjusting settings to find what worked best for us.

we're using the 250, the lower end of the corio 2 version. Works fine, image quality is superb.

We're using it as a keyer between the pc and the output of our old videonics mx-pro. That way we can switch behind any text we want to put up, and still use a lower third graphic behind the words (generated in EW for us) before overlaying it over the IMAG cams we've started using.

Basically our setup mean the tv one unit is always in line and keyed, and also upscales the sd video feeds to 1024 X 768, and they look great too. Just remember to black out whichever feed you're not using at the time-either the pc or the live feeds...

So the consensus is that the corio stuff is working fantastic for keying graphics.

Any thoughts on the chroma key side of things? Do those Datavideo units look good? Don't know if DTV Engineer is watching this thread, I know you've mentioned keying gear recently in other threads. Any advice on a sub $1500 chroma key unit? Obivously I'd be open to others than I've listed. I'm looking to do it past my switcher, so not necessarily interested internal keyers.
