安东尼Burokas: There's a big difference between business chat apps and video production apps. Sometimes there's a bit of pushback as to why the remote guest has to connect to your system. "Why can't we just use WebEx or 团队 or Zoom or Google Meet because that's what we use to do?" The main reason is that those business chat apps are not designed to enable producers to get isolated audio--we just call it ISO--and video from each person separately. 商务聊天应用在云端将所有东西混合在一起. Video production apps are designed so that we can adjust audio levels, 获得, 每个人都是平等的. We can also color correct, reposition the camera feeds as we need for our show. 有专用的连接号码, 我们可以预先构建显示和多视图, 提前知道, 谁会通过哪个远程摄像头连接进来.
This is simply not possible with the business chat apps. 现在, if there's some overarching reason why a person can't or will not connect directly to the video production app, you can use the business chat apps and then use some tricks to try and get that person's individual feed from the business chat app into your production. For instance, you can dedicate a laptop to each person you need an ISO from . 很多人都是这么对待极速的. You can pin or highlight (whatever each app calls it) that one person on that one device. And then you can use free software like NDI Screen Capture to grab that screen and bring it into your video production software of choice over the local area 网work. Or you can send that screen out on HDMI and capture that as you would any other camera feed.
有趣的是, Microsoft 团队 has integrated the ability to send out individual NDI streams for each caller, 只要来电的人不多就行. You're not going to get 50 ISO feeds over NDI from one computer. And you need to have enough local bandwidth and enough CPU processing power to handle multiple NDI streams at the same time.
它也需要一些设置. They've got a whole page on, on all the different steps you need to do to make this happen properly. 最后, 音频仍然混合在一起, but having ISO app output capability built into 团队 is a nice feature. 如果您使用团队，请尝试一下.
