On the 20th February 2013, ARRI announced they were refreshing their product line with the new ALEXA XT (Xtended Technology). The day after on the 21st February in conjunction with Codex, we used the ALEXA XR with Codex Capture Drives on the worlds first ARRIRAW 120FPS shoot. All taking place in our usually green screen but this time blacked-out Studio 2 at Waterloo Film Studios. Working as a gaffer along side DOP Stuart Bentley and Camera Assistant James Hills we filmed dancer Leah Debrincat against a black background with a few hard light sources testing the full latitude of the new upgraded ALEXA XR. The film was directed by Laura Redpath from Codex, and coloured by Greg Fisher.
Shooting with Cooke S4’s at T2.8-T4 the ALEXA XR was recording at 120FPS ARRIRAW onto 512GB Codex Capture Drives, and then transferred using the Codex Capture Drive Transfer Station. The final video was edited in Final Cut and then coloured in Baselight. The ALEXA XT, XT M, XT Plus and XT Studio cameras will replace all previous models except for the original ALEXA. Owners of existing ALEXA cameras will be able to purchase individual upgrades that deliver most of the features of the XT configuration.
It seems that ARRI and CODEX have both listened to the feedback from professional users of the ALEXA and produced a faster and more affordable way to shoot with the ARRIRAW configuration. ARRIRAW has become the output of choice for feature films, including The Avengers and Skyfall and Codex recorders have become the recording standard. The new range of camera models come with the new XR Module, that replaces the original SxS module. Users now have the ability to shoot at the ALEXA’s highest quality image output, inside the camera. The XR Module is an integral part of the new ARRI ALEXA XT camera it provides several recording options in a single package.
ARRIRAW at up to 120FPS (16:9) can be recorded onto a high performance Codex Capture Drive. In addition to ARRIRAW, Apple ProRes or Avid DNxHD can also be recorded to a Codex Capture Drive, making longer recording times possible (up to 2.1 hours of ProRes 4444 at 24FPS or up to 15 hours of ProRes Proxy). With an SxS Adapter it is possible to record ProRes or DNxHD to a single SxS PRO card, thus protecting the inventory of existing cards. The XR Capture Drive offers a number of different paths into post, using proven CODEX workflows.
The Codex XR Capture Drives are identical in form to the current Codex Capture Drives and are compatible with the Codex Vault, Codex Capture Drive Transfer Station and the Codex Capture Drive Dock (USB-3). These provide production-proven options for offloading and moving material from production into post. Codex Capture Drive’s are exceptionally fast and rugged and will come in the sizes of 512 GB XR Capture Drives.
In Camera Filters:
Recently Schneider Optics announced that they were manufacturing the new In-camera Filter Module (IFM-1) Based on a design made by Clairmont Camera’s Andree Martin and Alan Albert the IFM-1 allows a secure and precise positioning of these custom made filters behind the lens. The filter system works by using a specially designed magnetic filter holder that replaces the light baffle in the ALEXA, once in place the holder allows you to place the specially manufactured filters behind the lens of the camera. Filtering behind the lens rather than in front will reduces weight, reflections and operational complexity. Once the camera has been fitted with the internal mounting assembly, filters can be installed or changed in the ALEXA in a few minutes. The in camera filters cannot be stacked so to get around this Schneider have created combinations of filters.
Currently the following filters are available:
Optical Flat
IRND 3, 6, 9
IRND 3, 6, 9 with Black Promist 1/8
Black Promist 1/8
IRND 3, 6, 9 with Black Frost 1/8
Black Frost 1/8
The Ultra Precision Multi Coated In-Camera IRND filters used with the IFM-1 are based on innovative technologies that assure highest image quality and perfect color balance. The option to have an in camera filter tray also now offer the opportunity for the cinematographers to now add nets in-camera, where as before camera assistants would painstakingly take time to stick nets to the backs of each individual lens. Clairmont have also designed an in-camera, unlike streak filters used in a matte box, no glass is used in the filter ring. Therefore, there is no focus shift or possibility of unwanted reflections caused by the filter being placed in the optical path. The filter ring can be rotated to any position desired during installation. The In-Camera Filter Kit for the ALEXA will interface with most PL lenses but is not compatible with Zeiss T2.1 16mm, 24mm, 32mm, Arri Macro 16mm, 24mm, and 32mm as well as Cooke Series II and III 18mm, 25mm and 32mm. Lens extenders may also interfere with the kit’s filters. The ALEXA In-Camera Kit is also available without filters, so users may buy only the filters desired. Schneider Optics anticipates adding other popular filters to fit the kit.
True anamorphic with a 4:3 sensor: For the most effective use of anamorphic lenses, each ALEXA XT model is equipped with a 4:3 sensor, the same size and shape as a Super 35 mm film frame. This is crucial for delivering the unique and cinematic widescreen look that can trace its origins back to the CinemaScope films of the 1950s. It is a look that has long been appreciated by cinematographers, directors and the viewing public. An anamorphic de-squeeze license is included with all XT cameras, as is a high speed license for filming at up to 120 fps. The 4:3 sensor will also be useful on non-anamorphic productions as it permits significant reframing of the image in post, similar to shooting 4-perforation 35 mm.
More efficient VFX through ubiquitous lens metadat: Lens metadata is invaluable for a speedy VFX post workflow, which is why all ALEXA XT models are equipped with an LDS lens mount. The ARRI Lens Data System (LDS) reads the position of all lens rings and writes them into metadata in every format ALEXA can record. Over 41 lens models have LDS built-in, including the ARRI/ZEISS Master Anamorphic, Master Prime and LDS Ultra Prime series, the Master Macro 100 and the ARRI/FUJINON Alura Lightweight Zooms. For all other lenses it is possible to store the lens table inside the ALEXA by using the Lens Data Archive feature.
Super silent XT Fan: ALEXA cameras are already among the quietest digital cameras, but an even quieter fan has become available and ARRI has incorporated this new fan into the ALEXA XT models, providing an extra safety margin in very quiet or very hot environments.
Future proof – upgrades for existing ALEXA cameras.
The ALEXA system was designed for professional customers, providing high build and image quality, but also modular upgradability and long product cycles to ensure a solid return on investment. Having already released various upgrades, licenses, options and free-of-charge Software Update Packets, ARRI is now offering upgrades for existing ALEXAs that provide most of the functionality of the XT cameras. These upgrades include the XR Module, In-camera Filter Module IFM-1, Viewfinder Mounting Bracket VMB-3, Viewfinder Extension Bracket VEB-3, XT Fan and the anamorphic de-squeeze and high speed licenses.
