ARRI发布轻便紧凑型摄影机ALEXA MINI


(2015年2月23日,慕尼黑)ARRI发布全新的ALEXA Mini摄影机。它是ARRI ALEXA系列的最新成员,其体积紧凑、轻便小巧,而优异的影像质量却与业界黄金标准的ALEXA毫无二致。ALEXA Mini专为特殊拍摄而设计,可完美作为ALEXA完整拍摄套装的一部分。它的问世使得剧组不再需要第三方摄影机协同拍摄,整个拍摄都可以使用被世界各地广为信赖的ALEXA系统。


为了使这样一款小型摄影机也能保持ARRI闻名的坚固做工,ALEXA Mini采用了多项与众不同的设计:高度集成化、密封的电子系统;轻量化的炭质外壳;直接连接于全新内置影像传感器卡座之上的钛合金PL卡口,即使安装大型镜头时亦可保持超稳定的法兰距。ALEXA Mini灵巧敏捷,坚固耐用,便于携带,可被方便地装在背包内,或置入随身行李箱中。


ALEXA Mini具备多种操控方式:无线遥控;配合ARRI MVF-1多用途取景器作为常规摄影机;或配合机载小监视器,以机身的快捷键操控使用。它重量极轻,可置于手持支架上舒适拍摄,小体积和静音运行又让它成为狭窄环境下的理想选择。对称的机身设计可让它在任何方向进行拍摄,例如上下颠倒和直立肖像拍摄。机身具备多个附件安装孔,安装方式可尽由您创意发挥。另外,ALEXA Mini的可更换镜头卡口可由ARRI AMIRA的卡口替换,因此也能够安装B4卡口电视镜头和EF卡口照相镜头。


ALEXA Mini配备了4:3影像传感器以及自动的变形镜头压缩画面还原功能,帧率范围从0.75至200 fps。录制格式为ProRes,或无压缩的ARRIRAW——可录制于机内的CFast 2.0储存卡上,或录制于专门设计的外置Codex录机中,该录机更能同时录制多达四台ALEXA Mini的信号——非常适合于多机拍摄的场景,例如360°背景板的拍摄,也使得最终调色更加方便快捷。


强大的内置功能同样是ALEXA Mini高效一体化设计的核心。内置镜头马达控制器能够让新款马达直接连接到钛制PL卡口上,而ARRI镜头数据系统(LDS)可提供精确到帧的元数据,这些数据无论于现场还是后期都能够帮您节省时间和成本。Wi-Fi连接能力可使用iOS或Android设备来遥控摄影机功能,例如控制马达驱动的内置ND滤镜:它能够让您对光线条件的变化做出快速响应,而无需在摄影机上添加笨重的附加设备。


ALEXA Mini机身设计非常适合安装于新一代的无刷遥控头、无人机和其他特殊设备上。它的体积足够紧凑,即使带有标准的PL卡口镜头,摄影机也能安装在轻型和空间要求苛刻的摄影机机架上,例如带有陀螺仪的航拍系统。超凡的低照度表现是它成为水下摄影的完美工具。现在各大厂商正在为它开发专用的防水外壳。


如同ARRI AMIRA一样,ALEXA Mini也能够录制4K UHD ProRes影像,让实时4K UHD超高清输出和便捷的工作流程成为可能。更重要的是,ALEXA Mini与所有其他配备ALEV III影像传感器的ARRI摄影机一道,都能够提供卓越的影像质量。这其中,我们关注的不仅仅是空间分辨率,更包括色彩、肤色和高动态范围(HDR)。因此,无论您选择的输出格式是HD,2K,4K UHD或者其他的原生分辨率(例如无压缩ARRIRAW 2.8K或ProRes 3.2K),ALEXA Mini会始终保持各个影像元素的完美均衡,而且面向未来,无惧于日后任何新标准的出现。


ARRI ALEXA Mini预计于2015年5月开始出货,于3月起接受预订。ALEXA Mini的原型机将于2015年2月24至26日的英国视频博览会(BVE)的J30展台展出。

ARRI ANNOUNCES COMPACT AND LIGHTWEIGHT ALEXA MINI


(23rd Feb. 2015, Munich) – ARRI announces the new ALEXA Mini, a versatile additional tool in the ARRI ALEXA camera range that combines a compact and lightweight form factor with the same unparalleled image quality that has made the ALEXA system a gold standard for the industry. Designed for specialized shot-making, the ALEXA Mini perfectly complements a full ALEXA shooting kit and allows crews to eliminate the complications of working with third-party cameras by keeping everything within a single system that is trusted all over the world.


To maintain ARRI’s famously rugged build quality in a small and lightweight camera, a number of unique design solutions have been incorporated. These include highly integrated and environmentally sealed electronics, a lightweight carbon housing and a solid titanium PL mount that connects directly with the new internal sensor mount to ensure a super-stable flange focal distance, even when using large lenses. Nimble in use and hardy on set, the ALEXA Mini is a go-anywhere tool, easy to transport in backpacks or as carry-on luggage.


The ALEXA Mini can be operated in a number of ways: by wireless remote control, as a normal camera with the ARRI MVF-1 multi viewfinder attached, or with an on-board monitor and controlled via the user button interface on the camera body. Light enough to be comfortably held at arm’s length in a hand rig, its compact size and extremely quiet operation also make it ideal for tight shooting conditions. The symmetrical design permits filming in any orientation, including upside-down and in portrait mode, while multiple accessory points enable highly creative mounting solutions. In addition, the ALEXA Mini’s interchangeable lens mount can be replaced with any of those designed for the ARRI AMIRA, allowing the use of B4 video and EF mount stills lenses.


Equipped with a 4:3 sensor, automatic de-squeeze mode for anamorphic productions and frame rates of 0.75-200 fps, the ALEXA Mini records ProRes or uncompressed ARRIRAW either in-camera to CFast 2.0 cards or to a specially-designed external Codex recorder that can record image streams from up to four ALEXA Minis simultaneously – a compelling option for multi-camera setups such as 360° plate shots. Images from the ALEXA Mini will perfectly match those from all other ALEXA cameras, making the final grade easier and quicker.


Integrated functionality is at the heart of the ALEXA Mini’s efficient and self-contained design. A built-in lens motor controller allows new active lens motors to be connected directly to the titanium PL mount, while ARRI Lens Data System (LDS) technology provides frame-accurate metadata that can save time and money both on-set and in post. Wi-Fi connectivity means that iOS or Android devices can be used to remotely control camera functions such as the motorized internal ND filters, which permit rapid responses to changing light conditions without adding bulk to the camera configuration.


The body design is optimized for use with new-generation brushless gimbals, multicopters and other specialized rigs. It is compact enough in the lens direction to allow the use of standard PL mount lenses even on lightweight and space-constrained rigs, such as gyro-stabilized aerial systems. The camera’s superb low-light performance makes it perfect for underwater work; dedicated underwater housings are currently being developed by leading manufacturers.


Like the ARRI AMIRA, the ALEXA Mini can record 4K UHD ProRes images, facilitating real-time 4K UHD output and simple pipelines for high-resolution deliverables. More importantly, the Mini and all other ARRI cameras with the ALEV III sensor offer unrivalled overall image quality by focusing not just on spatial resolution, but also on other parameters such as colorimetry, skin tones and High Dynamic Range (HDR). This is equally true whether the chosen output is HD, 2K, 4K UHD or one of the native resolution outputs like uncompressed ARRIRAW 2.8K or ProRes 3.2K, ensuring that images captured with the ALEXA Mini are future-proof, whatever new industry standards emerge.


The ARRI ALEXA Mini is scheduled to begin shipping in May 2015, with orders being taken from March. A prototype of the ALEXA Mini will be on show at the British Video Expo (BVE) from February 24-26, in Booth J30.
