电视广播 and The Next Generation of Professional 在线直播 Software
这 Telestream Wirecast 演示作为赞助的技术演讲在 流媒体连接2023.
最近发布的电视流 Wirecast 16, 我不得不说，这是我们迄今为止功能最丰富的版本, 特别是对于长期使用Wirecast的用户. There are some features that were recently released that are game-changers in live streaming production.
什么是无线广播?
让我们从快速概述开始. Wirecast is a cross-platform, Mac and Windows application that allows you to capture, produce, and stream. 在捕捉方面，Wirecast在增加HDMI灵活性方面做得非常出色. SDI, USB, iPhone, NDI, IP，以及这些来源的混合-你可以混合和匹配. 连接设备真的很容易. 今天的演示中我有几个连接在一起.
用户界面概述
在UI中, 你有一个预览窗口和你的实时输出, meaning that you can monitor your live output as you are looking over and composing or building out your next shot. 在预览实时窗口中, 我们使用五个主层，您可以在其中添加徽标, lower-thirds, png, PSDs, 显然相机, 视频回放——无论你需要什么来讲述你的故事或你的现场制作.
你可以在Shot属性面板中查看每个图层本身. So, 本质上, 在UI本身, 当你添加相机源或视觉源时, 一切都在这里. 整个工具就在你面前. 真的不需要任何挖掘，去寻找你需要的规模, 移动, 添加, 或者调整你的主层的生产.
ai驱动的虚拟助手
来看看Wirecast最近发布的内容. 在虚拟助手中, 我们提供了10年的工作流程, 故障排除, 以及这个机器学习/人工智能助手的技术建议, 我在测试时把厨房的水槽扔在上面.
我只是随便问它一些问题, 以及我已经多次回答过客户的问题, 虚拟助手不仅提供了一个干净的, 精确的答案, but it was also more of an educational thing: "Check these things outside of Wirecast, 就像在外围, or it may actually be in a driver or it may be actually be in the cable or connection."
Wirecast's Virtual Assistant is 1) a very robust walkthrough technical advice 故障排除 tool; 2) it's support at the instant you need it. So the Virtual Assistant is probably, I'm going to have to say the #1 new release for Wirecast 16.
新的视频过滤器
第二个新功能——来自我的制作背景——是视频过滤器. 每个摄像机都有自己的图像传感器和自己的色温, 你可以通过数字方式改变色温. You could use an actual white balancing card and balance out the color temperature of that camera, 但是假设这些都不是你能得到的. 你可以用Wirecast的视频过滤器来做.
So we look at a video--this MP4 here in the demo--and we can go to Video Filters and 添加 our filters. 我们有每把钥匙的赌注. 这样我们就能拉一个绿幕了, 我们可以拉一把活的钥匙, 但它们也有lut，如果我们去那里, 它只是添加了一个覆盖层. But for producers in the professional world of color correction cards or warming cards, I can now go into Photoshop and I can actually create warming and cooling filters and bring these into Wirecast, 我可以调整镜头的色温. 如果我注意到我的视频看起来有点热. 我可以加个滤色镜. 我有这些过滤器可用. 如果你不知道如何在Photoshop中制作立方体文件, 联系一下电视流媒体, 我们会把这些滤色器拿出来给你. 我大部分时间用这两种冷却方式，这两种加热方式. 有时候我也会用曲线来增加饱和度.
Video filters can be applied to the source itself or they can be applied to the every layer inside of that source. 假设有个摄像头, 较低的三分之一, 还有一个标志, I could single out the camera and 添加 the filter to that specific source so you could do the whole shot or particulars in that picture-in-picture.
可封闭的区域
Our third new feature was a large customer request for our house of worship education, 体育, 招待那些周三会来的顾客, 使用占位符构建周五或周六的产品, 构建下三分之一, 加上所有的标题, 还有标识. And then a producer would come on Friday for the show and sometimes the producer wouldn't quite understand the full features of Wirecast and maybe bump their production and not know how to kind of retract or go back and fix that.
所以我们实际上增加了可锁定区域. 如果你点击编辑锁定, 你可以锁定主图层, so you can't be moving the main layers around covering 较低的三分之一 with a video source, or you can lock the preview window so you can't drag anything like I accidentally just did. 或者你可以锁定镜头编辑面板到任何比例，定位，旋转. Or you could lock the entire UI, so all I can do is switch and stream, switch, or record stream.
可锁定区域可能并不适合所有人, 但如果厨房里有很多厨师, 这是防止错误发生的一个很好的工具.
SRT摄取
In previous versions we have had SRT output, and now with Wirecast 16 we have SRT ingest. 现在我们可以从任何地方拉入SRT作为Wirecast的贡献提要. 也许它的一个用途是在建筑物上使用拉斯维加斯的SkyCam.
现在我们可以拉出那个源然后用我们的下半部分来修饰它, 我们的商标, 我们的信息, and use Wirecast to pull that in and push that out to whatever destination you were trying to go to.
变焦一体化
一个备受期待的发布是我们的Zoom集成. So now we can go to Zoom and we can actually 添加 an invite link or their meeting info or join that Zoom meeting, 这样我们就能召集15个远程演示者了.
So, a use case--in that everyone's familiar with Zoom--let's say you send out four Zoom links to your presenters like today. And then we could pull those presenters from Zoom to Wirecast over WebRTC and have them as individual sources in Wirecast. 所以, Zoom熟悉你的演讲者, but Wirecast being your full production tool to dress up with lower-thirds logos, 演讲, 标题卡, 不管你在做什么, 你可以把和极速的会面提升到专业水平, 就像一个专业的制作.
其他新功能——荣誉奖
这是Wirecast 16中最大的五个版本. 这里有几个值得注意的地方:一个是PTZ相机控制. 实际上，我们在Wirecast中内置了PTZ摄像机控制, and it's not just pan-tilt-变焦; it's pan tilt, 变焦, 集中暴露, 白平衡调整, 和——最重要的是——预设. 使用PTZ相机，你可以用一个相机拍摄多个镜头. Wirecast为您提供了非常简单的服务. 比如，你可以在节目开始前设置三个预设. 预设一可以是推，预设二可以是拉. 有了那个摄像头，你可以有一个推/拉，你可以切换预设. 当然这是PTZ摄像机，所以我们有平移，倾斜和变焦. 所以, complete control over the PTZ cameras and as many PTZ cameras as you have hooked up. So you would have to select each PTZ camera, and you can go in and make those adjustments.
对我们来说，另一个重要的因素是社交媒体. 当你在Facebook上直播的时候, 抽搐, 和YouTube, 评论将进入Wirecast, 现在你可以在这里调节它们. You can select individually or batch select and push those comments to your live stream.
我们还拥有多达5个独立的“小皮肤”或玩家. So you can choose how you want that social media comment to come in and be displayed.
第三，我们有库存媒体库. 这一点很少被提及, 我用它——如果不是每周都用的话, 至少每个月用我自己的作品. Stock Media Library is our partnership with StoryBlocks and they're offering us over 600,000个视频元素, 照片, 音乐, 所有的免版税. 所以你订阅了Wirecast, 我们一会儿会讲到, 您将获得免费访问股票媒体库, 你可以在哪里加入一些东西来增强你的流. Maybe you don't have a drone shot over a mountain and you need that for your story. 你可以把它拉进去. 假设你的制作需要一些音乐. 所有的版权都是免版税的，就像我们以前说的，版权链清晰. 股票媒体库是一个非常大的资产提供给你.
Wirecast的新订阅模式
最后，Wirecast正在向a 订阅模式. 过去，工作室的入门价是599美元，专业版是799美元. Now we have a 订阅模式 where an annual subscription for Studio is $299, 而Wirecast pro则是399美元. 但很多人都是合同工，. 也许他们只有几个直播节目，他们就完了, 所以他们只需要两个月. 我们还为Wirecast Studio和Wirecast Pro提供每月订阅, 也试图使它成为最灵活的入门级用法. So whether you have one production or you need it yearly, we've got a 订阅模式 for you.
