Hi Glen,
No unfortunately I wasn’t able to discover any more info to answer my questions about the BMD Decklink HD Extreme and Vegas.
Instead we are going to try using the Vegas Secondary Monitor feature, in combination with a graphics card that will output 1920×1200 via HDMI to an HDMI monitor. Still awaiting delivery so I can’t report on how well it works.
This approach won’t give us the analog/digital capture/print capabilities I was hoping for, it just addresses monitoring.
I figure we might still consider the BMD card in the future if we have proof that it works, or a unit to try.
Regards
Dave
