Review: Blackmagic Design HyperDeck Studio HD Plus

In the job of a streaming media producer, 一般有两种拍摄方式:单相机和多相机. 在一般情况下, 客户将希望为视频录制的镜头按需交付, or to save a higher-quality record of what was live streamed. While most cameras that can internally live stream, 有些人喜欢佳能XF705, cannot record and stream at the same time. For multi-camera shoots where you have a switcher, along with the individual camera footage, 你经常可以通过记录切换器的程序输出来减少编辑时间. 的 HyperDeck Studio HD Plus is a good tool for accomplishing these tasks, 无论你是在工作室还是在场地的固定位置拍摄. This unit would be difficult to use on location in many instances, even though it has a 12v DC input as well as AC power.
单位本身(图1) 并不是特别大，大约是U-Matic大壳录像带的大小. 对于熟悉传统记录的人来说，控制非常简单, 玩, 停止, 倒带, 快进控制. 此外，还有一个按钮用于在HDMI和SDI输入之间切换.

设置和设置
用于设置设备, 在前面板的最右边有一个旋转旋钮来辅助菜单和设置按钮，这个旋钮有助于在2英寸视频监视器上的各种菜单项之间移动. 监视器显示正在输入或播放的视频，以及用于音频的VU仪表. 的re is a 1/4" headphone jack for monitoring audio. 如果你没有耳机, 您可以按住左上角的扬声器按钮，激活一个小型单声道扬声器, so you can verify you are getting sound. As soon as you let go, it shuts off.
您将在菜单中做的最重要的事情是设置编解码器. You have a choice of three: H.264, Pro Res, and DNxHD (Avid). 的re are four quality settings for H.264, but you can’t do 4K recording. 如果你想输出4K H.264文件，你必须先在Pro Res或DNxHD录制，然后通过另一个程序将其编码为4K. 第二件最重要的事情是设置正确的音频通道数量.
Once you’ve set all of the recording parameters, 开始录音, all you need to do is hit the Record button. 单元本身检测传入的分辨率，所以这很简单. 我使用 the HyperDeck hooked up to the output of a Blackmagic Teranex 表达 to up-res standard definition to HD, and it was fairly simple. HyperDeck Studio HD Plus检测到较大的分辨率，然后调整编解码器比特率以匹配. When using this unit with the Teranex 表达 to up-res, you need to make sure you use the Teranex settings. Otherwise you get unstable video, no video, or quarter-screen output. 如果你输出的视频分辨率超过1080p，这些设置是必要的. 第一个, make sure the output is set to 12G, 而不是“12G四分频”,” which divides the image between the two outputs and loop-outs. 下一个, set the reference to “External,” even if you don’t have external sync being input to the connector. 这让我抓狂了一年多，直到我终于从他们的技术支持那里得到了正确的建议.
数字传输
我一直在我的传输系统中使用HyperDeck Studio HD Plus来数字化旧录像带, and so far it has worked flawlessly. Integrated with the Teranex 表达 (下面的图2)——或者其他标准转换器——Hyperdeck绝对可以提升您的业务.??

由于HyperDeck Studio HD Plus只有数字HDMI和SDI输入, if you want to use an analog source, you will need an analog-to-digital converter. Blackmagic Design makes a number of 迷你转换器; one I find useful is the Analog-to-SDI converter. 的re are several others out there from AJA, and other brands of varying quality.
现场使用
For field use, the HyperDeck has a 12v, 4-pin XLR power input. If I were going to use it in the field, 没有交流电源的地方, 我可能会使用我的旧安东/鲍尔相机电池的适配器，并调整它插入12v插头. If you need a field recorder designed for field use, I recommend Blackmagic Design’s Video Assist monitor.
录制媒体选项
使用HyperDeck时，您可以灵活地记录媒体. 前面板有两个SDXC插槽，后面板有一个USB-C接口(下面的图3).

对H.264 recording, pretty much any V30 SDXC Card will work. For UHD ProRes or DNxHD recording, you will need V90 cards. 我使用 OWC Atlas 256GB卡 我为一个客户把一段婚礼视频从Umatic转到了4K ProRes. I also liked using the USB-C port with a portable SSD.
我将LaCie 500GB强固型硬盘和他们的2tb便携式固态硬盘连接起来，以便进行更长的录音工作. 的 HyperDeck Studio is great for recording long jobs in the field, and not having to worry about swapping cards as they fill up. For standard definition transfers of H.264, the 2TB cards will record over 360 hours! 我使用这些LaCie驱动器的唯一问题是，2TB驱动器喜欢在Mac上格式化为Ex-FAT，以便被HyperDeck看到.
有什么不喜欢的?
Is there anything not to like about this device? I only found one thing that bothered me: 的re is no power switch. Once you plug in the HyperDeck Studio, it’s on. 如果你想关掉它，你必须拔掉插头，这取决于你的设置，可能是一个真正的麻烦. 我不确定黑魔法公司为此节省了多少制造成本, but I can’t believe it was worth it.
Overall I found the HyperDeck Studio simple to setup and use. 的 quality of the recorded video is very good. 我现在的H.264 encoding setup uses a Blackmagic Design H.264 Pro Recorder going into an older HP Z800 workstation. 的 HyperDeck Studio HD Plus takes up a tenth of the space.
我可以很容易地将它集成到我的传输设置中，并使用它来记录我在一年中拍摄的多个会议. 能够记录多个摄像机和PowerPoint演示文稿的混合切换到HyperDeck Studio HD Plus, with a hard drive attached to record for the whole day, it will be a lot better than juggling multiple SD cards.
If you are in the business of recording and streaming conferences, the Blackmagic Design HyperDeck Studio may be an indispensable tool.
