NAB 2024: vMix会谈vMix 27和缩放集成

的主要特征之一 vMix 27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 流媒体特约编辑肖恩·林 of SLVLive 在vMix展台 NAB 2024. Barker还快速演示了该功能的工作原理.

肖恩林: 我和vMix的希斯·巴克在NAB 2024, 我们将讨论vMix的最新版本, 哪个是vMix 27. 快速概述一下27的一些重要特性?

希斯巴克: vMix 27最大的特点是我们的变焦集成. 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. 另一件很酷的事情是历史上我们有vMix Call, 只有8个来电者. 变焦在输入数量方面没有限制. Where the limits lie 是 bandwidth--so you've got 30 Megabits of bandwidth to work with, 这相当于5个高清1080P源. 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, 如果你把它们作为小的个体输入, 看起来会很棒. 这是主要的一个.

肖恩林: 这与桌面捕获有什么不同?

希斯巴克: 在桌面捕获, 你一次只能带一个进来, 而现在你可以把他们都带进来. 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. 这一切都在vMix中运行,所以你不需要第二个显示器来录制.

肖恩林: 对我来说, 当我看或者使用这个功能的时候, 干净的输入是非常重要的, 因为当你使用桌面捕捉引入缩放输入时, 你总是能得到他们的名字和他们的连接带宽. 里面总是有事情发生.

非常干净,非常棒. And then you can lay your overlays, like your lower thirds and stuff on top of them. 我们有一个演示,稍后可以给你们看.

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, 你可以把整个节目和它的样子发给他们. 这包括他们和所有的东西, 这样他们就能完全了解发生了什么, 比如直播之类的.

肖恩林: 传统上,当你做的时候 混合- 与视频, 你把视频发给他们,然后再发给他们, 这就是我们在说的吗. 我们可以选择送回什么. 这可能会让观众感到困惑,但更糟糕的是音频的混合. 我们不想给他们传回音频. 那么你是怎么做到的呢?

希斯巴克: 所以vMix本身会为你混合负. I recognizes a 变焦 input, and if it's a 变焦 input, it means the participant could be talking. 所以我们永远不会把它送回去. 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: 没有回音,没有尖叫声,回音,没有反馈. 只是幸福.

希斯巴克: 现在你仍然可以得到一些回音或者类似的东西,如果你的参与者, 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. 你肯定想要,vMix总是说,测试,测试,再测试. 但就混合-而言,它在vMix中非常可靠. So what I've done is set up a little demonstration of how the 变焦 integration works. 在这里,我在手机上设置了变焦. 所以我以变焦呼叫者的身份呼叫vMix. 这是我,这是我从vMix得到的缩放反馈. 现在我可以把它放到我事先准备好的镜头里, 比如这个有一堆图层给我所有的变焦参与者, 这些家伙, 其中一个就是我. 我把拇指从相机上拿开对准自己,然后直接切到那个. 所以我可以变成我自己,试着控制我自己. 好了. 然后切换到另一个镜头,切换到另一个镜头,切换到我自己. 所以,这是一种更漂亮的变焦能力, something that's really customized for what look you 是 looking for rather than what 变焦 wants.

肖恩林: 添加变焦输入有多容易? 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. 在缩放管理器中,你可以从参与者列表中选择. 当参与者出现在变焦会议上, 你可以右键点击它们,你可以选择添加它们作为一个新的输入, or you can add them as a existing 变焦 input if you've already got one built there. 所以在vMix中添加人非常非常简单.

肖恩林: 然后一旦你添加了,比如说1 2 3或4个输入,切换有多容易? 谁负责输入?

希斯巴克: 如果你看这里的缩放输入, I can right-click on there and I can change my participant to be whoever I want. 你可以在这里进行转换. 这非常非常简单.

肖恩林: 优秀的. 好的,非常感谢你,希斯. 这是在NAB 2024上对vMix 27的观察.
