ARRI Updates ALEXA for 96p DNxHD support

ARRIRaw Converter also gets 4k update

By James DeRuvo (doddleNEWS)

ARRI has announced an update to the Alexa Software Update Packet which will add DNxHD support for high frame rates up to 96 fps. The update will pertain to the ALEXA XT and Alexa Classic cameras that support the XR Module. In addition, ARRI also updated their ARRIRaw Converter for ultra high definition support in open-gate sensor mode.

The high frame rate update is greatly dependent on what recording medium that is used to capture and record the image. In order to get high frame rates up to 96fps, users have to record to XR Capture drives or the 120 GB CFast 2 cards, which falls a tad short at 90fps. Users who record to the 64GB SxS Pro cards end up with just 60fps and a 32 GB SxS card will receive no appreciable benefit at all as they are limited to 30p.

In addition, the new update also fixes a bug that caused issues with audio quality when outputting the video, as well as audio sync with all DNxHD clips. ProRes encoding also gets a tweak which helps with greater stability. Lastly, there’s the vague reference to “SUP “a number of refinements and bug fixes for all ALEXA cameras.”

ARRI also announced an update to ARRIRaw 3, their converter software for both Windows and Mac. ARC has recently come out of Beta and the new 3.0 ARC update brings ultra high definition upscaling of ARRI footage to UHD-1, which is a resolution of 3840×2160. ARC 3 also supports ARRIs open-gate sensor mode on the Alexa XT, and the Alexa XT Black and White camera. There’s also a pixel-masking option which gives experienced users the ability to repair defective pixels in images through GUI or Command line options.

ARC 3.0 includes: • Support for ALEXA XT Open Gate sensor mode
• Support for the ALEXA Black and White camera (available through the ARRI Rental Group and ARRI Rental Partners)
• Uprez to 4K or UHD-1
• Support for user pixel mask

Both ARC and CMD are based on the ARRIRaw SDK, a software toolkit which is used in several postproduction tools from members of the ARRI Partner program, such as Flame/Lustre from Autodesk, Pablo from Quantel, OSD from Colorfront, Digital Vision Nucoda, Adobe Premiere CC, Foundry Nuke and Hiero, Eyeon Fusion, Assimilate Scratch and many more.
