ALEXA Mini SUP 4.0
ARRI proudly announces the release of Software Update Package (SUP) 4.0 for the ARRI ALEXA Mini camera. With a compact and lightweight carbon body and the same image quality as other members of the ALEXA family, the ALEXA Mini has already proved a huge success in many different configurations and on countless production types. SUP 4.0 will widen the ALEXA Mini's versatility and appeal still further, with new features that include internal ARRIRAW and Open Gate recording for uncompromised image quality, as well as 4:3 recording modes optimized for anamorphic lenses.
4:3 ProRes recording modes
Activated through the purchase of an ALEXA Mini 4:3 License Key at the ARRI License Shop, these three new ProRes recording modes 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.
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.
ECS and Lens Data Archive
Electronic Control System (ECS) support in the ALEXA Mini has been extended to include the Lens Data Archive, allowing custom lens files to be created and used.
Super 16 HD recording
Allowing the use of Super 16 lenses with the ALEXA Mini, the new ProRes S16 HD recording mode uses a 1600 x 900 sensor cutout and scales it to full HD 1920 x 1080.
Transvideo StarliteHD5-ARRI improvements
The touchscreen interface of the Transvideo StarliteHD5-ARRI monitor now has a more neutral look and new functions including record start/stop, access to the top three user buttons and playback.
Support for the Camera Control Panel CCP-1
The soon-to-be-available CCP-1 is essentially an MVF-1 viewfinder without an eyepiece. It can be used with the camera in place of the viewfinder and provides full access to the UI home screen and menu, as well as a small monitor image. It can also be used in combination with the MVF-1 by daisy-chaining the monitor from the second EVF connector of the CCP-1.
Additional features of ALEXA Mini SUP 4.0
- Extended SDI metadata -- SDI outputs now embedded with standard ARRI metadata.
- Wi-Fi toggle via user button -- to quickly enable and disable the Wi-Fi interface.
- Selectable viewfinder zoom position -- adjustable via the LCD panel buttons.
- Longer exposure times -- no restrictions on exposure times longer than 1/24 s.
