0 4 C a m e r a At the inception of the ALEXA project we looked carefully at what is needed to create digital image and audio in the most efficient manner, including what it takes to get that content quickly into post and distribution. During our discussions with industry experts, it became obvious that a modern digital camera system requires much more than just a new camera with a great sensor - lenses, recording media, recording codecs, electronic accessories, mechanical accessories, batteries and post production have to mesh perfectly for a smooth journey of content from set to post. The system has to be complete and all its parts tightly integrated. The challenge was tremendous in scope, more vast and complex than the creation of the ARRICAM system. The Universe Another important realization was that we did not have to invent everything ourselves. On the contrary, we decided to create a system with an open, future-proof architecture that can tap into existing standards and best-of-class solutions. Where existing methods did not satisfy our demand for highest quality and efficiency, we worked closely with companies such as Apple, FUJINON and others to integrate their technologies and experience into the ALEXA system. Additionally, we built on the strengths of existing relationships, such as our decade long close cooperation with ZEISS. The result is the most complete and powerful digital production system ever built. ARRI Technology At the center of the system is the ALEXA camera, consisting of ARRI core technologies: sensor, image processing electronics and image processing software, all combined under the term ARRI Imaging Technology (AIT). Since no existing approach to electronic viewfinders had won us over, we built our own. The ARRI Electronic Viewfinder EVF-1 is based on the combination of an innovative display with ARRI illumination, electronics, optics and hardware. All this is supported by precision mechanical and optical components that were designed based on years of experience in building motion picture cameras. ALEXA is, of course, compatible with the wide range of ARRI mechanical and electronic accessories, including matte boxes, follow focus units, the ARRI Wireless Remote System, the new High Definition onboard Monitor HDM-7, the ARRI bridge plate system and the ARRIHEAD. This includes also numerous accessories developed especially for ALEXA. Third Party Components We are grateful for the fantastic contributions from a number of companies who have worked closely with us, integrating their technologies and products into the ALEXA system. The big news is that ARRI is now one of only a few companies world wide that are offering Apple ProRes hardware products for efficient Direct to Edit functionality. Recording the same standard high quality codec that is also used natively by the Final Cut Pro editing software is a revolutionary step in digital production. Not only is this the fastest and easiest method to get high quality images and sound from the camera into an editing system, it also streamlines the entire off-line/on-line workflow. D irect T o E dit In order to record ProRes encoded image files onto an on-board recording medium, we have licensed the SONY SxS driver software, which allows the fast data rates necessary to record even ProRes 4444 data onto SxS memory cards.
ARRI/FUJINON Zooms ARRI/ZEISS Primes & Zooms Panavision and Stills Camera Lenses Our new partnership with FUJINON has resulted in a new family of zooms: the Alura Zoom 18-80 and Alura Zoom 45-250. These ARRI/FUJINON zooms combine the highest optical performance with a practical size, weight and price and are a perfect match with ALEXA. Our on-going, long-term relationship with ZEISS has produced the greatest range of matched PL mount lenses available, all 100% compatible with ALEXA. This range includes the Master Primes, Master Macro 100, Ultra Primes, Ultra 16 lenses, Lightweight Zoom LWZ-1 and the Master Diopters. Playing on the strengths of this lens range, ARRI and ZEISS are introducing a new Master Prime 12 lens, while continuing to work on many other projects. Apple ProRes Codec ARRI Imaging Technology Electronic Viewfinder Mechanics and Optics Accessories Third Parties On-board Batteries SONY SxS Cards Third Parties On-board Recorders Third Parties ARRIRAW Partner Program open, Future Proof Architecture The ALEXA system is based on an open architecture with many industry-standard interfaces and compatibility to third party products. This provides more choice to the customer and, in combination with a number of modular components on the camera, makes the system future proof. We are closely working with third party on-board recorder manufacturers to ensure compatibility with ALEXA. This includes physical mounting issues, remote start/stop, metadata recording and ARRIRAW debayering. While there are a large number of recorders that can record HD video, the ARRIRAW T-Link certificate allows an easy identification of ARRIRAW capable equipment. Currently, certified recorders are available from Codex, S.two and Keisoku Giken. To guarantee a smooth workflow in post when working with ARRIRAW, ARRI has been working with numerous third parties that have enrolled in the ARRIRAW Partner Program. Their products can natively read and process ARRIRAW data. ARRIRAW capable equipment and tools are available from: ARRI, AVID with the ARRIRAW Avid Plug-in, Digital Vision, DVS, Filmlight, Glue Tools, Iridas, MTI and Pomfort. A complete overview and links to ARRIRAW Partners, equipment, tools and post facilities are available at www.arridigital.com/contacts/partnerprogram. A large variety of on-board batteries are available for ALEXA since the camera supports both the Gold and the V-mount standard, in back or top mounted configurations. To protect the investment in ALEXA, three major components of the camera are specifically designed in a modular fashion. First, the module that holds the memory cards is removable. When different card standards are available in the future, this module can be easily replaced with other storage modules. Second, the camera electronics, which comprise the whole right side of the camera, can also be removed and replaced with an upgraded electronics with advanced features. And last but not least the Exchangeable Lens Mount (ELM) system allows the use of PL as well as Panavision and stills camera lenses, expanding the option of the filmmaker.
