Arri Alexa

ALEXA is a compact, lightweight and affordable digital camera that will redefine the limits of motion picture capture with ultra-fast workflows and image quality akin to 35mm film. From major motion pictures and high end dramas to commercials, music videos and mainstream TV, ALEXA suits a wide variety of applications and budgets.

More than just a camera, ALEXA represents an entire image pipeline. By combining proprietary ARRI technology with ubiquitous tools from industry-leading partners, ALEXA stands alone as the most complete and powerful digital production system ever built.

Different projects have different production requirements, budgets and distribution channels; the equipment chosen has to be flexible enough to accommodate those differences. The unique construction of the ALEXA and ARRIFLEX D-21 allows for various output signals to be generated, accommodating diverse production needs and pipelines.

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.
