The question is way out of my area of interest, but you might look at the products from this company.

@john_dennis - What’s @Troyxo asking for?

@Grazie

My guess. Broadcast monitor adapter.

https://www.edius.net/edius-i-o-cards.html

Support for EDIUS 7, EDIUS 8, and EDIUS 9 (driver is included in all versions)

HD Spark: HDMI out + Audio out

HD Spark Pro: SDI out + Audio out

@john_dennis - So, is he asking for the same for VP? In the past I’ve had output through an ACEDVideo to a Pro Broadcast Monitor. Could that be it?

@Grazie

Your guess is probably better than mine.

Cheers! 😉

This are very outdated videocards, I think. I had a Storm 3G long time ago, it was only for HD.

What is available today are Blackmagic and AJA cards. For example the Blackmagic Intensity Pro 4K and the Decklink 4K Extreme 12G.

While those cards work well in Vegas for SDR, I am not so sure if they work also for HDR. For HDR the output was broken (I use the Decklink 4K Extreme 12G with HDMI to my Atomos Sumo, but the HDMI connection is not quite stable yet - still testing if the SDI connection is better working).

Frankly spoken, a nice graphic card for the so called secondary preview would be usefull too - especially if you wish to go for HDR (with an HDR monitor, that will work together at least). Cards like the Blackmagic or AJA cards has the major advantage, that they produce really standardized outputs - but here the question is, if you need that really.)
