ARRI has released the latest Software Update Packet (SUP) for the ALEXA. This camera firmware fixes a few minor bugs in timecode and ProRes recording, but there are also two major upgrades.
Recording ProRes to the SxS cards can now range from .75fps up to 60fps. This applies to all of the ProRes formats except the data-intensive ProRes 4444, which can record up to 40fps.
The other major upgrade is in the precise synchronization between cameras for 3D stereo shooting. While the ALEXA has already been used to successfully capture 3D (most notably in Martin Scorsese’s upcoming Hugo Cabret), a new cable kit and camera master/slave mode now allow for the locking of sensor timing, HD-SDI output phasing, fps, shutter, timecode and camera trigger.
The SUP 2.1 is available to all ALEXA owners from the ARRI website. Camera owners must complete a one-time registration to download the file. The new software can then be loaded into the ALEXA using an SD card.
