Cámara Alexa Mini

Save time in post

With the ALEXA Mini the difficulties we faced in the past are eliminated. You won’t have to solve grading problems trying to match images from ALEXA´s cameras with small cameras from other manufacturers. With the ALEXA Mini all images come from the same sensor and share the same colour space than the ALEXA classic family with their famously natural colorimetry and pleasing skin tones. The ability to use CDLs and 3D LUTs in-camera for on-set colour management will also reduce time and money spent in post.

Integrated lens motor control and ND filters, perfect for gimbals and multicopters

The ergonomics of the ALEXA Mini has been created under the influence of a practical thought having in mind the 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. Its performance for an underwater work is perfect because of its capacity of handling low-lights spaces.

Greater efficiency through integrated functions

An integrated lens motor controller allows new active lens motors to be connected directly to the titanium PL mount, so focus, iris and zoom settings can be controlled from ARRI hand units without an additional external box. It incorporates a system of wireless remote control, as a normal camera with the ARRI MVF-1 multi viewfinder attached, or you could operate it with an on-board monitor and controlled via the user button interface on the camera body.  This system allows you to control the camera with accessories of Arri or with a computer, tablet or mobile phone of last generation. Within the compatible accessories of Arri with the Alexa Mini highlights the Arri WCU-4, which in combination with the new motors C-force Plus will allow you to control camera and lenses remotely, without the need for receptors. It can also be configured via the MVF-1 electronic viewfinder just like the Arri Amira.

Optics with LDS mount such as Cooke S4 / i T2 or Zeiss Master Prime T1.3 offers metadata information which is transmitted to the camera and the WCU. This facilitates the work of the focus puller at the time of reporting the aperture, depth of field and focus ring position. The active PL mount from Arri also could feed the optical servo of lenses as the Fujinon Cabrio without power cables.
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.

Integrated ARRI Lens Data System (LDS)

ARRI’s Lens Data System® (LDS) generates highly accurate lens metadata for use on set and in post. When using an LDS lens on AMIRA’s LDS mount, information about iris, zoom position or focus is visible in the viewfinder and the files will have lens data embedded in the recorded footage. The data also allows lens mapping to pre‑marked focus rings and reduces the time and expense involved in achieving complex visual effects in post.

Compact, lightweight and self-contained, the ARRI ALEXA Mini is a versatile additional tool in the ALEXA camera range. These include highly integrated and sealed electronics, lightweight carbon housing and a solid titanium PL mount that connects directly with the new internal sensor mount.

LICENCES FOR ARRI ALEXA MINI

This license, enabled by ALEXA Mini SUP 4.0, provides three new ProRes recording modes that access the full 4:3 sensor area and support the use of anamorphic lenses. The first mode records the highest 4:3 resolution possible, while the other two de-squeeze and re-scale the recorded images in-camera for an efficient, specialized workflow. Monitoring paths for all 4:3 modes offer SDI setups featuring dual 1.5G or 3G outputs.

ProRes 4:3 2.8K records the full 4:3 sensor area (2880 x 2160) and can be used with anamorphic or spherical lenses. It offers frame rates up to 50 fps and an optional 2x anamorphic de-squeeze for the EVF and SDI monitoring paths.

ProRes 2.39:1 2K Ana. records a 2.39:1 standard 2K format (2048 x 858), which does not require any cropping or scaling in post. Due to the in-camera scaling the data rate is reduced, allowing recording speeds up to 120 fps.

ProRes 16:9 HD Ana. is for situations where the look of anamorphic lenses is desired but the end product is full 16:9 HD without letterboxing. This mode also supports recording speeds up to 120 fps.

+ARRIRAW

The ARRIRAW License Key, also enabled by ALEXA Mini SUP 4.0, allows ARRIRAW to be recorded to the ALEXA Mini’s in-camera CFast 2.0 cards by wrapping the files in an MXF container. Like ARRIRAW, the new MXF/ARRIRAW format is uncompressed, unencrypted, and contains audio and metadata. Only the packing is different, so third-party ARRIRAW processing tools such as DaVinci Resolve and Baselight have to be updated with a new SDK, which ARRI has provided for them. ARRIRAW Converter supports MXF/ARRIRAW from version 3.4, available free of charge on the ARRI website.

MXF/ARRIRAW clips do not require specially formatted CFast cards, so MXF/ARRIRAW and QuickTime/ProRes clips can be mixed on the same card.

MXF/ARRIRAW 16:9 2.8K records an area of 2880 x 1620 and supports frame rates up to 48 fps.

Internal MXF/ARRIRAW Open Gate recording

Installing both the ALEXA Mini 4:3 License Key and the ALEXA Mini ARRIRAW License Key on a camera activates the MXF/ARRIRAW Open Gate 3.4K recording modes enabled by SUP 4.0.

MXF/ARRIRAW Open Gate 3.4K has a resolution of 3424 x 2202 and a maximum recording speed of 30 fps. As with the ProRes 4:3 recording modes, an optional 2x anamorphic de-squeeze is available for all monitoring paths and a dual 1.5G or 3G SDI setup is supported.

In order to offer anamorphic ProRes productions an easy way to capture some shots in MXF/ARRIRAW, three additional Open Gate 3.4K recording modes are being introduced:

• MXF/ARRIRAW 4:3 2.8K (OG 3.4K)
• MXF/ARRIRAW 2.39:1 2K Ana. (OG 3.4K)
• MXF/ARRIRAW 16:9 HD Ana. (OG 3.4K)

These modes record 3.4K Open Gate at up to 30 fps, but the monitoring paths reflect the corresponding 4:3 ProRes modes. The active image area is noted in the metadata, so postproduction tools will crop the images automatically. ARRIRAW Converter and other tools that support the new ARRIRAW SDK are able to override that information and return to the full Open Gate frame if required.
