Netflix has approved the ARRI ALEXA 35 Xtreme camera for 4K Originals, which includes support for ARRI's new ARRICORE compressed RGB codec. This approval provides productions with a data-efficient workflow for premium image quality, allowing for longer recording times and faster downloads while maintaining post-production flexibility. The focus is on ARRICORE's debut as a supported capture option within Netflix's ecosystem, enabling higher frame rates with specific caveats.
The inclusion of ARRICORE in the Netflix Production Guide signals a critical shift toward data-efficient premium workflows. For high-end productions, the codec addresses the massive storage overhead of RAW formats without sacrificing the metadata control required for complex color grading. By approving a compressed RGB format for 4K Originals, Netflix is validating a middle-ground approach that prioritizes on-set agility and faster offload times. This approval likely sets a precedent for how other streaming platforms will treat next-generation compressed codecs from major hardware manufacturers. Watch for adoption rates of ARRICORE in VFX-heavy episodic productions to see if it replaces ARRIRAW as the standard high-end delivery format.
The ALEXA 35 Xtreme, first announced by ARRI in July 2025, serves as a high-speed successor to the standard ALEXA 35. According to reports from Newsshooter and FD Times in mid-2025, the internal hardware was redesigned with a more powerful processor and faster memory to handle the thermal and data demands of 660 fps recording. To protect existing investments, ARRI offered a factory upgrade path for current ALEXA 35 owners at a cost of approximately €15,900, as reported by ARRI in July 2025. This hardware flexibility follows a broader industry trend where manufacturers like Sony and RED are increasingly offering modular or software-licensed performance tiers rather than entirely new sensor blocks.
Beyond high-speed gains, the Xtreme introduced significant workflow improvements including 10% lower power consumption and five-minute pre-recording buffers in HD, per Arri.com in July 2025. These features, combined with the Netflix approval, position the camera to compete directly with specialized high-speed systems like the Phantom Flex. In early 2026, industry testing by Cinematography.net noted that the ARRICORE codec’s 13-bit log encoding renders images nearly identical to 18-bit ARRIRAW, with only infinitesimal differences visible on scopes. This technical parity is likely what secured its quick certification for the Netflix ecosystem, which maintains a rigorous '90% approved footage' rule for its branded Original content.
