ARRI ALEXA XT Plus

Camera ARRI ALEXA XT Plus is the most versatile line of ALEXA XT (Xtended Technology). This camera with new functionality, reliability and ergonomics.

The main differences between cameras line chemotherapy are:
• Built-XR in the sidebar (instead of SxS) for recording ARRIRAW (now ALEXA camera can provide video recording at up to 120 frames per second at 512 GB XR Capture Drives. It is also an opportunity to record ProRes 4444 at a rate of 120 Read More

Product Description

The camera features ALEXA XT Plus
– Built-in camera wireless remote control receiver lens
– Built-in tilt sensors and rotation
– Additional connectors lens control and output signals
– Auxiliary power supply

Specifications:

Faster, lighter and more affordable ARRIRAW
All ALEXA XT cameras come with the new XR Module (Xtended Recording), a side panel that was co-developed with Codex to replace the previous SxS Module. The XR Module allows in-camera recording of uncompressed and unencrypted ARRIRAW, ALEXA’s highest quality image output, all the way up to 120 fps in full image quality. This not only makes for a smaller, lighter and more affordable camera package, it also simplifies setup and operation while avoiding unnecessary cabling.
ALEXA XT cameras record ARRIRAW onto exceptionally fast and rugged 512 GB XR Capture Drives, including advanced and time-saving features such as capturing the ASC Color Decision Lists (CDL) and a checksum for each frame into metadata. Once removed from the camera, the XR Capture Drive offers a number of different paths into post for every budget and time schedule demand, using the proven Codex workflow.

More efficient use of metadata for VFX
Metadata lens are invaluable for quick work with the effects of fasting, so all models are equipped with ALEXA XT lens mount c LDS. Lens Data System ARRI (LDS) reads positioning and lens and transmits them in a special format for recording as metadata in parallel to any video format in which the image recording. More than 41 models of lenses support LDS, including ARRI / ZEISS Master Anamorphic, Master Prime and LDS Ultra Prime series, Master Macro 100 and ARRI / FUJINON Alura Lightweight Zooms. For all other lenses, there is the possibility to store tables in the internal memory ALEXA using the Lens Data Archive.

Less weight and easy to work with ND filters
The indoor unit filters IFM-1 installed in the model ALEXA XT is designed for basic sensitivity EI 800 and eliminates the need for external neutral density filters in a bright and sunny weather. The filter installed in front of the lens, not in front of him, saves time, reduces weight, get rid of reflections and difficulties with his replacement. The module IFM-1 uses precision filters IRND, manufactured using innovative technologies and provide high image quality, perfect color balance for all eight densities of up to ND 0.3 ND 2.4.

Comfortable and easy fixing of the viewfinder
To ensure maximum comfort for the operator, the new folding arm for viewfinder VMB-3 has a much stronger and more rigid construction, that partly achieved by using a support system with two 15 mm light rods. This system also contributes to the rapid change of position of the camera, such as from a tripod on a crane or steadycam, because  accessories such as focus controll or motors for lens are installed on it and do not clutter up the foundation of the camera. Also as well as a separate accessory for fixing the viewfinder, you can use a folding arm VEB-3, which holds the viewfinder in a safe place when you move the camera.

Currently anamorphic image sensor with a 4:3

For the most efficient use of anamorphic lenses ALEXA XT camera equipped with a matrix with the same aspect ratio as 35mm film and Super 4: 3. It is important to obtain a unique widescreen motion picture CinemaScope, which consistently since the 1950s. This aspect is the most popular among producers, directors and spectators. License anamorphic shooting, as well as to capture the license at a rate of 120 K / sec, including all varieties chamber ALEXA XT. Sensor with a 4: 3 ratio is also convenient to use, and for non-anamorphic shooting because it allows sufficient reframing the image in the post to make a video like 35mm with 4 perforations.

Super quiet cooling system  XT
ALEXA camera is already known as the quietest digital camera, but the new fan in ALEXA XT models is now even quieter and it provides additional reliability in the quiet and hot places.

Updates for the existing ALEXA cameras
ALEXA system has been developed for professional users, providing not only the highest build quality and image, but also a modular design with the possibility of modernization, focusing on the long life cycle of the product and providing a guaranteed return of investments. Already released various updates, license, paid options as well as for free use. Now, ARRI offers updates for the existing ALEXA cameras, which provide most of the functionality of the XT cameras. These updates include the XR module, filters’ module IFM-1, viewfinder’s  folding arm VMB-3, viewfinder’s  folding arm VEB-3, XT fan and licenses for anamorphic and high-speed shooting.

Powerful and Unique ProRes & DNxHD Options
As an alternative to ARRIRAW it is also possible to capture ProRes or DNxHD in-camera. ALEXA XT cameras provide two unique ProRes recording features: ProRes 4444 XQ, the highest quality ProRes codec, and ProRes 3.2K, the ideal recording resolution for an up-sample to 4K UHD or for extra room to resize, reframe, rotate or stabilize a 2K or HD image. Additionally, the XR Capture Drives allow for significantly longer recording times and faster speeds: ProRes 4444 can be recorded for a total time of 107 minutes (at 24 fps) and can be recorded as fast as 120 fps.
Recording onto SxS PRO or SxS PRO+ cards is also possible: with the SxS Adapter ProRes or DNxHD can be recorded to a single SxS PRO or SxS PRO+ card, thus protecting the inventory of existing cards. And with the CFast 2.0 Adapter it is possible to record onto CFast 2.0 cards, the same medium used by AMIRA, the new documentary style camera.
A high speed license for filming at up to 120 fps in 16:9 and 96 fps in 4:3 is included with all ALEXA XT cameras.
