ALEXA has been designed to function as both a motion picture camera and a broadcast camera. For TV production, the time and cost savings as well as the extraordinary simplicity of ALEXA workflows will transform budgets and schedules, while the cinematic image quality will stagger viewers. For features, the sheer variety of outputs, functions, lenses and accessories will enable filmmakers to realize their visions without ever feeling restricted by technology.
Whether your production is destined for the silver screen or the TV screen, ALEXA will empower you to tell your story in exactly the way you think it should be told, with pictures of breathtaking richness and detail.
ALEXA is unique in that it can simultaneously record Apple QuickTime/ProRes files, output uncompressed HD video or uncompressed ARRIRAW data. This output versatility makes it ideal for a myriad of productions and workflows from telenovellas to feature films.
As the best recording media for the QuickTime/ProRes files, ARRI has chosen SxS cards because of their high data throughput. Two SxS cards fit into a module on the camera's left side for convenient on-board recording and are hot swapable.
Two outputs which can be configured to 3G or 1.5G HD-SDI deliver an uncompressed high definition video stream with various options such as recording in 4:2:2 or 4:4:4 and ITU Rec709 or Log C tone mapping and color matrixes.
The two recording links can alternatively be used to output the ARRIRAW T-link signal, which can be recorded by a number of certified third party on-board recorders. ARRIRAW is the only way to access the full potential of ALEXA's sensor which has color and dynamic range capabilities far beyond standard HD. ARRI's own ARRIRAW Image Converter (ARC) provides image reconstruction features for the Windows, LINUX and Mac OS platforms. As a result of long term corporate initiatives with key development partners within the ARRIRAW Partner Program, a number of post production tools can now natively work with ARRIRAW files.
These output formats are well established standards that integrate the cameras seamlessly into the existing HD infrastructure.
