Product Description

The ALEXA Mini 4:3 License Key enables 3 new ProRes Recording modes:
– 4:3 2.8K (2880 x 2160) @ up to 50 fps
– 2.39:1 2K de-squeezed (2048 x 858 de-squeezed from 2560 x 2145) @ up to 150 fps
– 16:9 HD de-squeezed (1920 x 1080 de-squeezed from 1920 x 2160) @ up to 150 fps
Recordings are possible in all currently supported ProRes flavors up to ProRes XQ.

The ALEXA Mini ARRIRAW License Key enables in-camera 16:9 2.8K (2880 x 1620) ARRIRAW recording at frame rates of up to 48fps.
In combination with the ALEXA Mini ARRIRAW License Key, the ALEXA Mini 4:3 License Key will also enable Open Gate recording in ARRIRAW.
The following Open Gate Recoding Modes will be supported:
– Open Gate ARRIRAW (3424 x 2202) @ up to 30 fps
– Open Gate ARRIRAW with 4:3 2.8K preview path (3424 x 2202 with crop to 2880 x 2160 in viewing path) @ up to 30 fps
– Open Gate ARRIRAW with 2.39:1 2K desqueezed preview path (3424 x 2202 with crop to 2560 x 2145 in viewing path) @ up to 30 fps
– Open Gate ARRIRAW with 16:9 de-squeezed preview path (3424 x 2202 with crop to 1920 x 2160 in viewing path) @ up to 30 fps

 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,
– with an on-board monitor Transvideo Starlite ARRI
– controlled via the user button interface on the camera body.
Further operational settings can be made remotely when working with the ARRI WCU-4 hand unit.
Built-in Wi-Fi connectivity facilitates remote control of camera functions from iOS or Android devices, with no need for a special app. 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.The motorized and remotely-controllable internal ND filters permit rapid responses to changing light conditions, and help keep clutter around the camera to a minimum. 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. 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 important than this, however, is the fact that 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 image quality parameters such as dynamic range. Images from the ALEXA Mini are uniquely suited to next generation HDR (High Dynamic Range) displays, which are likely to play a role in defining future format standards. In addition, the ALEXA Mini’s camera speeds of 0.75 – 200 fps allow it to be used not just for slow motion shots, but also for HFR (High Frame Rate) acquisition, which might constitute another strand of future standards. ARRI’s holistic approach to image quality makes ALEXA the most future-proof camera system available today, and the safest investment for tomorrow. Two ALEXA Mini license upgrades are available, allowing users to get the most out of the camera’s 4:3 ALEV III sensor. The 4:3 License Key enables ALEXA Mini to record ProRes in 4:3, 4:3 cropped or 16:9 anamorphic and to de-squeeze both the viewfinder image and HD-SDI signal. The ARRIRAW License Key enables the camera to record 2.8K 16:9 ARRIRAW both internally and to an external recorder. Open Gate ARRIRAW recording is possible with cameras that have both license keys installed. With the ALEXA Mini, no extra time need be spent on set configuring third-party cameras previously required for specialized shots, or on wrangling the image files coming out of them. Multi-camera setups such as 360° plate shots will be made simpler and faster by the external Codex recorder, which can record image streams from up to four ALEXA Minis simultaneously. The camera’s maximum frame rate of 200 fps means it can also be used for stunning slow-motion cinematography, saving further time and money on set by doing away with the need for a separate high-speed camera. The overwhelming advantage of the ALEXA Mini is that it marries such a compact and lightweight form factor with the same unparalleled image quality that has made the ARRI ALEXA system a gold standard for the industry. Combine the Mini with any other ALEXA camera and you will have perfectly matched images, even on anamorphic productions – thanks to the 4:3 sensor and automatic de squeeze function. Workflows will also be identical, with options to record ProRes or uncompressed ARRIRAW either in-camera to CFast 2.0 cards or to a specially-designed external Codex recorder. ARRI’s approach is unique in that it does not prioritize one element of image quality over any other. To achieve the highest overall image quality, ARRI uses bigger and better pixels on the sensor, rather than smaller pixels in larger numbers. The result is that ALEXA captures a wider dynamic range, truer colors, lower noise and more natural skin tones than other cameras, 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. This approach is vindicated by the huge numbers of professional filmmakers who choose ALEXA after extensive real world comparative testing.
