Here, we have collected ARRI’s white papers on the ALEXA camera line. This page will be updated as new white papers are released.

ALEXA Anamorphic De-squeeze White Paper – July 7, 2011

Starting with ALEXA Software Update Packet (SUP) 4.0, some new features can be added to ALEXA cameras through the purchase of a license. The first such feature is an anamorphic de-squeeze function. This paper describes the basics and history of the anamorphic process and how the de-squeeze function in ALEXA works. While the subject of the anamorphic process is fascinating and really deserves a longer treatise, this is meant as a simple primer to better understand the ALEXA de-squeeze function.

ARRI Look Files for ALEXA – July 5, 2001

Starting with ALEXA Software Update Packet (SUP) 4.0, ALEXA cameras can apply user-defined looks to customize the rendering of video images. The user can choose if the camera should apply an ARRI Look File only to the monitoring outputs (non-destructive mode) or if the look file shall be baked into the recorded image (destructive mode). Either way, the look file is embedded as metadata in the recorded QuickTime ProRes movie and in the ARRIRAW format.

This document addresses the use of ARRI Look Files with an ALEXA camera.
