教程:Blackmagic URSA广播和URSA迷你Pro 4.6K

In this tutorial I’ll look at two new cameras from Blackmagic Design: the URSA Broadcast, 4K摄影机(下面的图1); and the URSA迷你Pro 4.6K，是之前URSA Mini 4的升级版.6K (图2，在图1下面). These cameras are very similar but there are several key differences, and I want to show you both and then point out those differences so you can know which one would be the best for your work.

URSA迷你Pro 4.6K

让我们从URSA迷你Pro 4开始.6K. The first thing you'll notice about these two cameras is how similar they are and, 事实上, 没有配件, 尸体本身在外观上是相同的. URSA Mini Pro默认配备EF卡口, 用来装佳能镜头的, but you can get several other lens mount options if you need that as well. 它被设计成电影风格的摄像机, so it doesn't have a lot of features that would be typical for video cameras, because it's expecting you to do things like second-system audio, 例如. 它的顶部有一个内置麦克风, but most pros would use an on-camera mic mainly just for syncing up other audio later with an app, 比如PluralEyes.

On the front, of course, is the lens mount, and if you take off the lens you can see inside to the 4.6K的传感器在后面. One of the most noticeable changes on the front of the camera over the previous generation of the URSA Mini is the addition of the rotating wheel shown in 图3(下面). It’s a physical ND filter with four stages numbered 1, 2, 3, and 4. (实际上, 1设置为无ND过滤器, so it might have made more sense to call that 0 and number the others 1,2, 和3. 表盘可以转一圈, so if you get to 4--the darkest ND setting--and keep going, 一直回到没有ND的状态.

在相机的右侧(下面的图4)，有一个SDI输出和一个12v输出. The SDI out is typically going to be used for the viewfinder, 就像我们在广播节目上看到的那样, and the 12v also would provide the power for that viewfinder. 低于, there's an LANC controller for lenses that have that option and then a separate lens controller here. The rosette that's built in here is designed for the control handle that comes with all of the cameras.

背面(下面的图5), 我们有SDI, 哪个是12G-SDI, SDI在, 引用或时间码, 然后这里还有一个12v 4针适配器. 在图5中, you'll see that I've kind of modified my version a little bit by putting some Velcro on it, 因为我用的是非典型的电源, 但这通常是一个VLock电池支架. The Pro that was shipped to me had an SSD recorder on the back and the VLock battery mount was on the back of that. I've removed that so I could put my battery directly on the back. Normally there's a cover plate that would cover that opening, but this is where you would connect in with the other accessories that go on the back of the camera.

在相机的左侧(下面的图6) is where most of your controls are, because most operators stand to the left side of the camera. Another major change Blackmagic has made on this generation of the URSA Mini versus the previous generation is the addition of lots of controls outside of the LCD screen.

在左侧翻转的LCD屏幕(下面的图7) used to have a lot of controls behind it or on it through the menu system that you would have to access just for some basic operation of the camera, but they've improved on that by adding a lot of physical dials and a display on the outside that now shows you many of those common functions. 所以我们有两个轮子来控制音量. 这里有一些基本的函数, which will all show on the screen including your timecode, whether it's constant running timecode or timecode that only starts when you do your recording.
