Re: Intensity Pro issues OSX

Hi David,

I'm glad that made some sense of your observations. It can be a little tricky when you first transition to HD as there is a lot to learn.

[David Hansen] "Do all your cards with breakout cables operate this way (passing the downconvert to all ports) or is it a feature of the Intensity alone?"

No, different cards have different features. Two cards, DeckLink Studio and DeckLink HD Extreme 3, have a split down conversion function. This means that when you are working in HD, some outputs will be HD and others are SD.

Other cards have all their outputs downconverted when downconversion is enabled.

DeckLink Studio has SDI and analog connections and a full-time downconverter. When working in HD, the main SDI port will output HD-SDI, the dedicated SD-SDI output will output SD-SDI (no surprises there!), the component analog outputs will output HD analog video, and the composite and S-Video outputs will output SD analog video.

The DeckLink HD Extreme 3 has SDI, HDMI and analog connections. It features both hardware and software downconverters which can be enabled or disabled. The software downconverter works just as with your Intensity Pro and downconverts all outputs simultaneously. The hardware downconverter performs split downconversion. When working in HD, the HDMI port will be HD, the SDI A port will output HD, the SDI B port output will output SD, the analog outputs will output HD if set to component or SD if set to S-Video or composite.

That's a lot of information to absorb but I hope it makes some sense :-)
