NAB 2024: vMix Talks vMix 27 and 变焦 Integration
的主要特征之一 vMix 27 是 变焦 集成,使 远程生产商 to bring in (theoretically) an unlimited number of remote guests, vMix Senior Systems Engineer 希斯巴克 在采访中报道 流媒体 contributing editor 肖恩林 of SLVLive 在vMix展台 NAB 2024. Barker also does a quick hands-on demo of how the feature works.
肖恩林: I'm here at NAB 2024 with 希斯巴克 from vMix, and we're going to be talking about the latest release of vMix, 哪个是vMix 27. Quick overview, what 是 some of the big features in 27?
希斯巴克: The biggest feature for vMix 27 is our 变焦 integration. So it's possible to take all of our 变焦 callers from a meeting directly into vMix as individual inputs. So that means that you can bring in both their video and their audio independently so that you can do things like ISO record them or stitch them all together into a full layout with having your main caller and then various panelists on the side or something like that. 变焦有很大的灵活性. The other thing that's cool about it is historically we've had vMix Call, 只有8个来电者. 变焦 has no limits in terms of numbers of inputs. Where the limits lie 是 bandwidth--so you've got 30 Megabits of bandwidth to work with, and that equates to about five high-definition 1080P sources. 如果你有一个高级变焦账户, 你就可以使用1080P了, 但也可能是2360P, and if you've got them as small individual inputs, 看起来会很棒. 这是主要的一个.
肖恩林: How is this different from Desktop Capture?
希斯巴克: 在桌面捕获, you could really only bring in one at a time, whereas now you can bring them all in. And it was difficult to do things like bring in individual inputs and their individual audio so that you could do things like editing afterwards or recording ISO recording of each. 比这好多了. And it all runs in vMix, so you don't need a second display to record on.
肖恩林: 对我来说, 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 变焦 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. And then you can lay your overlays, like your lower thirds and stuff on top of them. We've got a demonstration that we might be able to show you a bit later.
And so not only can you bring in independent 变焦 inputs as ISO cameras or ISO participants, 我们也可以发送回去. 这是怎么做到的呢?
希斯巴克: vMix可以访问四个输出. You can just select one and whatever you're sending on that output will be what your 变焦 participants see as you in the meeting, 如果这说得通的话.
肖恩林: So that could be a program, but it could also be any other output that you designate as an output?
希斯巴克: 正确的. 如果你有主人的话, you might just send their direct camera feed because that's more natural for them, but if the 变焦 participants actually want to see what the whole show looks like, 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.
肖恩林: 传统上，当你做的时候 混合- 与视频, you're sending video in and sending it back to them, which is kind of what we're talking about. 我们可以选择送回什么. It can be confusing for the viewers, but worse is the 混合- for audio. We don't want to send them back audio. 那么你是怎么做到的呢?
希斯巴克: So vMix itself does 混合- for you. I recognizes a 变焦 input, and if it's a 变焦 input, it means the participant could be talking. So we're never going to send that back. 我们把它减去. 它是负的, 因此混合负, and so whatever we send back will be everything you want to send minus the 变焦 inputs.
肖恩林: So no echo, no squeal, echo, no feedback. 只是幸福.
希斯巴克: Now you could still get some echo or things like that if your participants, 例如, were not wearing headphones and had very loud speakers and they were getting noise back into their microphones. 所以这样的事情仍然可能发生. So you do definitely want to, as vMix always say, test, test, and test again. But as far as 混合- goes, it's pretty solid in vMix. So what I've done is set up a little demonstration of how the 变焦 integration works. In this, I've set up 变焦 on my phone. So I'm calling into vMix as a 变焦 caller. This is me here and this is what I'm getting as a 变焦 feed from vMix. And I can now bring that into a shot that I've pre-prep是d, such as this one that has a bunch of layers for all of my 变焦 participants, 这些家伙, 其中一个就是我. 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. 好了. 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, something that's really customized for what look you 是 looking for rather than what 变焦 wants.
肖恩林: How easy is it to add in the 变焦 input? 你能给我们讲讲吗?
希斯巴克: 确定. So it's a matter of going to Add Input in the bottom corner and then selecting 变焦 as your input, 单击OK, 寻找新的输入. And from here in the 变焦 Manager, you can pick from your participant list. And so as participants appear in the 变焦 meeting, you can right click on them and you can choose to add them as a new input, or you can add them as a existing 变焦 input if you've already got one built there. So very, very simple to add people into vMix.
肖恩林: And then once you've added, say 1, 2, 3, or 4 inputs, how easy is it to switch? 谁负责输入?
希斯巴克: If you look at my 变焦 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. 这非常非常简单.
肖恩林: 优秀的. All right, thank you very much, Heath. This has been a look at vMix 27 at NAB 2024.
