几乎直播流媒体:Blackmagic URSA

[注:本次赞助访谈在NAB 2014录制.]

在2014年拉斯维加斯NAB上, one of Blackmagic Designs' most intriguing announcements was the new URSA camera, which continues the company's forays into innovative camera design with a new Super 35mm production camera. Available in  July in both EF and PL lens mount models (with a B4 model coming later), the URSA records UltraHD to CF Fast and also supports HD formats.

它的两侧都有触摸屏, according to Blackmagic Senior Regional Manager Bob Caniglia, "where you can enter in metadata and see the display for audio metering, 专注达到顶峰, 和柱状图 ... because sometimes multiple people are working in the same crew. 这种方式, the focus puller can see what’s going on while the DP is looking over here, 音响师可以插进去看看这个仪表. 这使得它可以与多人互动, 它为单个用户提供了多个视角. 如果你是导演，你想站在一边, but you still want to see what’s going on framed in the shot, 你也可以这样做."

The camera is field-upgradable in the extreme: as updated components become available, users will be able to replace both the mount and sensor while keeping the camera body itself intact.

肖恩林 met with Bob Caniglia at the Blackmagic booth at NAB 2014 to discuss the camera and learn more about its innovative design, 功能, 和定位, and how it extends the 功能 introduced in earlier Blackmagic camera models.

Shawn: It’s 肖恩林 here for 流媒体 Producer at NAB 2014. 我们和Bob Caniglia在Blackmagic Design的展台, 我们今天来谈谈新的Blackmagic URSA相机. This is a little bit different from the Blackmagic Cinema Cameras. 给我们讲讲URSA吧.

Bob: URSA is the next evolution in our camera line: We’ve gone from a handheld model to a full-on production camera. We saw what people were doing with some of the smaller cameras by adding monitors and what-not, 所以我们决定增加一个10英寸的屏幕. 它不是触摸屏, 所以你有很好的视角, 它的角度一直向上, 或者一直向下, 这取决于你如何射击. 我们两边都有触摸屏. That’s where you can enter in metadata and see the display for audio metering, 专注达到顶峰, 和柱状图. You can enter in metadata just as you could in the Cinema Cameras, 在那里你可以浏览所有的菜单和东西. 然后在另一边, 我们还有一个, because sometimes multiple people are working in the same crew. 这种方式, the focus puller can see what’s going on while the DP is looking over here, 音响师可以插进去看看这个仪表. 这使得它可以与多人互动, 它为单个用户提供了多个视角. 如果你是导演，你想站在一边, but you still want to see what’s going on framed in the shot, 你也可以这样做.

尚伟:这个有一个4K超级35毫米传感器. 什么是镜头支架?

鲍勃:我们现在有两种坐骑可供选择. We have an EF mount and a PL mount, and we’ll ship those later this summer. Down the road we’re going to have a B4 mount for TV lenses. We’re also going to come out with another one that doesn’t have a mount at all. 它也没有传感器. 这是一个没有摄像头的摄像头. 它被设计成一个“奶酪盘”，你可以把它绑在上面, 说, 用佳能5D接HDMI输出, and this way you get everything you would want in the full feature of the camera, 这样你就可以在这里的CF快速驱动器上录制了. There are dual CF Fast drives, but you’ll also get all the audio. We have phantom power audio and of course all the other ins and outs that are on the body, 但这种方式没有传感器. 然后在某个时候, 当你想升级这台相机时, 相机机身本身可以重复使用, 但前板会取出支架和传感器, 你可以添加一个新的传感器, 所以将来这将是一个可在现场升级的相机.

Shawn: Can the user upgrade it, or does it need to be sent back to the factory?

鲍勃:这将是一个用户可升级的传感器. I’m sure some of the resellers might do it for some of the customers that don’t want to deal with it, 但这真的很简单. 前面有四个六角螺母.

尚伟:好的. So the maximum resolution this records is 3840x2160, which is UltraHD on CF Fast. 它记录到什么类型的编解码器?

Bob: We’re going to do Cinema DNG Raw and as well as ProRes.

Shawn: And of course, the camera supports lower resolutions such as standard HD?

鲍勃:是的. 也会有一些高清格式.

肖恩:那SD呢?

鲍勃:我不这么认为. 我想我们还是用高清吧.

肖恩:这是个好主意.

肖恩:价格和可用性?

鲍勃:确定. 这款相机的EF版售价5995美元. PL版本将是6495美元. 没有传感器的版本售价为4495美元, and the B4 mount will be announced pricewise and deliver date later in the year. But the first two EF and PLs will be shipping in the July time frame.

肖恩:非常感谢你，鲍勃. Some very exciting new camera announcements from Blackmagic here at NAB 2014.
