NAB 2024: vMix Talks vMix 27 and Zoom Integration
Among the key features of vMix 27 are Zoom integration, enabling remote producers 引入(理论上)无限数量的远程访客，vMix高级系统工程师 Heath Barker reports in this interview with Streaming Media contributing editor Shawn Lam of SLVLive in the vMix booth at NAB 2024. Barker also does a quick hands-on demo of how the feature works.
Shawn Lam: I'm here at NAB 2024 with Heath Barker from vMix, and we're going to be talking about the latest release of vMix, which is vMix 27. Quick overview, what are some of the big features in 27?
Heath Barker: The biggest feature for vMix 27 is our Zoom integration. 因此，可以将会议中的所有Zoom调用者直接作为个人输入输入到vMix中. 这意味着你可以独立导入他们的视频和音频你可以做一些事情，比如ISO录制它们或者把它们缝合成一个完整的布局有你的主讲人，然后各种小组成员在旁边等等. So, a lot of flexibility with Zoom. The other thing that's cool about it is historically we've had vMix Call, which was limited to eight callers. Zoom has no limits in terms of numbers of inputs. 限制在于带宽——所以你有30兆的带宽可以使用, and that equates to about five high-definition 1080P sources. If you've got a premium Zoom account, you'll have access to that 1080P, but it could be something like 2360P, and if you've got them as small individual inputs, that's going to look great. So that's the main one.
Shawn Lam: How is this different from Desktop Capture?
Heath Barker: In Dsktop Capture, you could really only bring in one at a time, whereas now you can bring them all in. 要做一些事情很困难，比如把每个人的声音输入进去，这样你就可以在之后进行编辑或录制每个人的ISO录音. So much better than that. And it all runs in vMix, so you don't need a second display to record on.
Shawn Lam: For me, when I watch it or when I use this feature, it's the clean input aspect that's super important, because when you bring in a Zoom input using Desktop Capture, you always get their name and their connection bandwidth. There's always something going on in there.
It's totally clean, which is fantastic. 然后你可以把你的覆盖层，比如你的下三分之一和其他的东西放在它们上面. We've got a demonstration that we might be able to show you a bit later.
所以你不仅可以把独立的变焦输入作为ISO相机或ISO参与者, we could also send back out. So how does that work?
Heath Barker: vMix has access to four outputs. 你可以只选择一个，你发送的输出将是你的Zoom参与者在会议中看到的, if that makes sense.
Shawn Lam: 这可以是一个程序，但也可以是任何你指定的输出?
Heath Barker: Correct. If you had a host, 你可以直接给他们发送视频，因为这对他们来说更自然, 但如果极速的参与者真的想看看整个节目是什么样子的, you could send them the whole show and how it looks. That includes them and everything as well, so that they've got a full understanding of what's going out, say to a livestream or something like that.
Shawn Lam: Traditionally when you're doing mix minus with video, you're sending video in and sending it back to them, which is kind of what we're talking about. We can choose what to send back. It can be confusing for the viewers, but worse is the mix minus for audio. We don't want to send them back audio. So how do you manage that?
Heath Barker: So vMix itself does mix minus for you. 我识别出Zoom输入，如果是Zoom输入，就意味着参与者可能在说话. So we're never going to send that back. We're minusing that out. It's minus from the mix, hence mix minus, 所以我们发回的就是你想要发送的所有内容减去Zoom输入.
Shawn Lam: So no echo, no squeal, echo, no feedback. Just happiness.
Heath Barker: Now you could still get some echo or things like that if your participants, for instance, 没有戴耳机，有很大的扬声器，他们会把噪音传回麦克风. So things like that can still happen. So you do definitely want to, as vMix always say, test, test, and test again. But as far as mix minus goes, it's pretty solid in vMix. 所以我所做的是建立一个关于Zoom集成如何工作的小演示. In this, I've set up Zoom on my phone. So I'm calling into vMix as a Zoom caller. This is me here and this is what I'm getting as a Zoom feed from vMix. And I can now bring that into a shot that I've pre-prepared, such as this one that has a bunch of layers for all of my Zoom participants, these guys here, and one of them is me. And I'll aim it at myself with my thumb off the camera and I can cut to that. So I can just switch into myself, try and manipulate myself. There we go. And then cut to another camera, cut to a different camera, cut to myself. So it's the ability to make a much nicer-looking zoom, 它是根据你想要的样子定制的，而不是Zoom想要的样子.
Shawn Lam: How easy is it to add in the Zoom input? Can you walk us through that?
Heath Barker: Sure. 所以这是一个问题，去添加输入在底部的角落，然后选择缩放作为你的输入, clicking OK, finding the new input. And from here in the Zoom Manager, you can pick from your participant list. And so as participants appear in the Zoom meeting, you can right click on them and you can choose to add them as a new input, 或者你可以将它们添加为现有的缩放输入，如果你已经在那里建立了一个. So very, very simple to add people into vMix.
Shawn Lam: And then once you've added, say 1, 2, 3, or 4 inputs, how easy is it to switch? Who is on that input?
Heath Barker: If you look at my Zoom input over here, I can right-click on there and I can change my participant to be whoever I want. There is where you would do your switching. It's very, very easy.
Shawn Lam: Excellent. All right, thank you very much, Heath. This has been a look at vMix 27 at NAB 2024.
