Review: Mevo开始 All-in-One Live Streaming Camera

The Mevo开始 is a little camera with a lot of built-in capability. Even though the Start can stream to social media directly from the camera itself, I'm going to take a look at it specifically for higher-end, multi-camera use as part of an NDI-based production.

关键特性

开始(下面的图1) has several key features that I am very excited about. 首先，它有自己的内置电池. Streaming capability and NDI|HX2 are also built-in.

背面有一个音频插孔(下面的图2). And you can remotely control the camera settings while it's streaming/sending NDI. That's a lot of features for a $399 list price.

In the video that accompanies this article, the camera is using WiFI to send the video over my local area 网work (LAN). Additionally, I have a mobile phone that is controlling the Mevo over that same LAN. The mobile phone is sharing its screen so that I can show you the Mevo control live, 当我使用它的时候.

In the Mevo app, you can reframe a shot (下面的图3). You can use your fingers to pinch the viewable area and virtually zoom in—essentially, a sensor crop. 看起来很不错. In the upper-right corner the Mevo app in 图3, you can see the camera view that's being sent out via NDI.

You could spend thousands of dollars for an NDI-capable camcorder, then pay hundreds of dollars to activate NDI in that camera. The Mevo开始 costs as an NDI license, and NDI is already activated in the camera. 你不需要额外付费.

在NDI平移-倾斜变焦(PTZ)头, 你可以远程控制变焦, 焦点, 虹膜, 快门, 和NDI的白平衡. But with an NDI-capable camcorder, you can't control any of that. Even after you spend thousands of dollars.

The Mevo开始 has an app that connects directly to the Start over the LAN (not NDI) .which lets you manually adjust the contrast, 快门, white balance, ISO, and digital zoom (下面的图4)—things some expensive camcorders can't do.

The Mevo开始 also has USB-C on the back, as shown in 图2. If you need to deploy the camera in front of a stage for a conference all day long, 或者其他的长镜头, the USB-C port enables you to plug in an AC adapter, 盒子里有哪些, 或者外部电池.

最有趣的是, Mevo also offers a USB-C-to-Ether网 adapter with integrated Power over Ether网 (PoE). This enables you to run PoE to the camera, which could be 200 feet away. PoE可以全天为摄像机供电.

此外, the ether网 connection will also pass the NDI feed back to your 网work, meaning that you don't have to worry about any WiFi interference. 还记得, NDI和HDMI或SDI一样好, and has the advantage of being able to use off-the-shelf 网working tools to connect multiple cameras.

In the Mevo app, all the way on the bottom left is the NDI button you can see in 图3. 这实际上是一个流媒体按钮. If you tap that when you’re already using NDI, you'll see the warning shown in 图5(下面).

流媒体和录音

你可以看到 图6(下面) that the Mevo has built-in modules to facilitate streaming directly to all the usual places: Facebook, YouTube, 抽搐, 等. It can also be set up with a manual RTMP destination.

You can also set it to record to a removable MicroSD card in H.264或HEVC (下面的图7). You can record in full 1080p at bitrates even higher than 40 Mbps.

Clicking another button brings up the Vimeo Producer subscription (下面的图8). If you’re going to use this to stream directly to a content delivery 网work or all those mentioned already, you can do video mixing in the device itself. It's also possible to use overlay graphics and more as part of a $15/month subscription to Vimeo Producer, which of course gets you into Vimeo as well.
