Overview
ALEXA is the first and only camera to support
Apple’s new ProRes 4444 XQ codec. With its target
data rate of 500 Mb/s (at 1920 x 1080, 30p) and low
compression ratio of 1.45:1, ProRes 4444 XQ is the
ideal choice for productions that are shooting for
premium image quality, are looking for extreme color
grading options or want to preserve the superior
tonal range of ALEXA's Log C signal.
ProRes 3.2K recording format is suitable for
productions requiring 4K UHD deliverables. The
rescale to 4K UHD only demands a small upscale
factor of 1.2x. Available to ALEXA XT and ALEXA
Classic cameras with the XR Module upgrade,
ProRes 3.2K is a new recording resolution that uses
3164x1778 photo sites from the sensor to record
a 16:9 3.2K ProRes file. The 3.2K sensor area was
chosen because it is the largest area that can still be
covered by almost all Super 35 PL mount lenses.
In addition the new ADA-5 enhanced debayering
algorithm further improves ALEXA's image quality in
all already available ALEXA recording resolutions as
well as 3.2K recording.
180° image rotation allows Steadicam operators to
flip their rig upside down for low mode shooting
and it rotates the image for the ARRI Ultra Wide
Zoom UWZ 9.5-18/T2.9. The rotation applies to EVF,
MON-OUT and REC-OUT. Internal recording is not
affected.
For high end workflows that utilize color on the set,
SUP 10 extends the number of recording modes that
support two independent HD-SDI outputs.
Previously only available in 16:9/HD/regular speed,
other recording modes now also benefit from a clean
Log C signal on REC OUT while a Rec 709 signal
with overlays and an optional ARRI Look File can be
output on MON OUT.
