Using Zoom ISO V3 with a DeckLink Quad plus a Mac Mini successfully, looking to build a second rig. Would an UltraStudio 4K Extreme 3 also work?
ASKED BY · Ed · SAN FRANCISCO · 10 OCT 2026 · ▶ 00:00:22
DeckLink Quad is better value than UltraStudio for new builds; UltraStudio is more expensive and suited for rack-mount or desk scenarios with legacy format support like Composite and RS-422.
RODECaster Video offers a cheaper alternative with 4K streaming via HDMI and NDI output for use with Zoom ISO and OBS.
DeckLink 4K Extreme works with Mac mini and Sonnet Thunderbolt enclosure; keep drivers updated and flash as needed. Tested with Desktop Video version 16 and recommend burning in with a 24/7 Zoom test meeting.

0:21Ed says, using Zoom ISO V3 with a DeckLink Quad plus a Mac Mini successfully, looking to build a second rig, would an UltraStudio 4K Extreme 3 also work? What do you think, Guy? Yes. Wow, man, a few words. Okay. All right, let's go to Courtney. Well, what you might think of is it depends on how many people you want to bring in.
0:53But you might look at the RODECaster video, either the big one or the little one, because they now have a mode that you can put them in where they stream up to 4K, the four of the HDMI inputs on the big one, three on the smaller ones, the core which is a lot cheaper than the 4k extreme 3 to give you four ndi streams that
1:20should probably work using zoom iso i haven't tried this so maybe you zoom iso users can speak as to if it can ingest four ndi streams at 4k at least with in with one with with at least it gives you some choice in OBS and other software as well. So that's a possibility. All right, Guy, you want to come back? Sure. Here's the 4K DeckLink Extreme, and I just pulled it off my Mac,
1:55and I have a quad card with the same kind of Sonnet box, actually the newer one that's Thunderbolt 3, and I can guarantee you that it does work. You do want to make sure that your drivers are up to date, though, and that if the car needs flash, that you flash it. Because sometimes when you go into the desktop videos version 16, it'll ask you to flash it.
2:16So just get that stuff taken care of before any kind of show so that it's all ironed out and then burn it in. We have a Zoom test meeting that we run 24-7. I highly suggest sending your bots into that. If you Google Office Hours Zoom test, you'll hit that page and you can bring in eight bots. For you, it depends on what you're trying to do with the quad.
2:34actually let's see using with the quad yeah so I have a quad and the Mac mini and then for a second rig if you're just trying to bring in one because all this has is left two cards in this box but you're gonna see that the extreme it's just one even though it has four SDIs this is just one in or out and then I
2:56have a second who makes that enclosure this is an old sonnet one this is okay Okay. Ancient. It's Thunderbolt 2, but I mean, it works. Yeah. Yeah. And have you experienced any issues with stability with the DeckLink drivers lately? I've heard mixed reports. I know a few people that have had problems with them. It's been good. In Rockstar? Yeah. 3.06 is good with version 16 of the DeckLink drivers.
3:24And I'm even running it on this test machine, which is GoldenGate. So I just let it burn in and it's been fine. All right. Chris Sabato. Guy, that's not the Ultra Studio you have there. That's just the DeckLink, right? This is Ultra Studio 4K, the exact extreme, the exact one he's talking about. Is it? And so it just has a... That doesn't look like the picture.
3:50No, no, no, no. Ultra Studio 4K Extreme. Yeah. When I... Oh, sorry. You're right. You're right. This is the DeckLink 4K Extreme. The Ultra Studio is the rack mount unit. So same technology. Yeah, yeah, yeah. Except it's $4,000, right? I read it fast. Yeah. That doesn't look like what I Googled. Gotcha, gotcha. But they all... Yeah, we have those at the shop.
4:15And no, actually, we do use a quad and a sonnet for our rig at Tenacious. And then we use the Ultra Studios for other processes. I'm trying to think of where those live. That would be my question. The Ultra Studio is like four times as expensive. So what are you doing that would require, maybe you have one on the shelf and that's why you would want to use it. But like if you're building a new thing and it's just for this, I feel like the Declan Quad is more bang for your buck.
