Operation of the Camera
This chapter covers tasks the user will encounter while using the
ALEXA. While previous chapters contained specific procedures for
basic use, this chapter will outline broader tasks and offer
recommendations and best practices, including camera configuration.
This chapter contains information and recommendations for internal
recording. The user is encouraged to adapt the recommendations and
workflow to individual and production needs.
Note: ARRI cannot be held responsible for the loss of any data in conjunction
with internal recording!
ALEXA cameras can be equipped with an SxS Module or the new XR
Module for internal recording. The XR Module is a camera side panel
that was co-developed with Codex, offering in-camera ARRIRAW,
ProRes, and DNxHD recording onto the exceptionally fast XR Capture
Drives. The new recording module replaces the SxS Module for all new
ALEXA XT models and is available as an upgrade for all ALEXA Classic
cameras. Cameras that are upgraded with an XR Module will no longer
output ARRIRAW over HD-SDI T-Link.
The classic ALEXA models with an SxS Module use Sony SxS PRO
cards for internal recording. SxS PRO cards have an ExpressCard34
form factor and are available with a storage capacity of 8, 16, 32 and 64
GB.
File System
SxS PRO cards need to be formatted in the camera before they can be
used for recording. The ALEXA initializes SxS PRO cards with the
Universal Disk Format (UDF) file system. This file system is read-only
for computers, which means data can be copied from the card to
another device, but the data cannot be manipulated on the card itself
and no data can be added to the card.
