ARRI ARRICORE RGB codec cuts data rates by 50 percent

The introduction of this codec addresses the primary bottleneck in high-end digital cinematography: the massive storage and processing costs associated with uncompressed RAW workflows. By moving the debayering and encoding process into the camera hardware, ARRI allows productions to maintain high dynamic range and post-production flexibility while doubling recording times on existing Codex Compact Drives. This shift signals a broader industry move toward intelligent in-camera compression that does not sacrifice the metadata control typically reserved for RAW formats. Watch for third-party post-production tools like Blackmagic Design and Film Light to finalize their SDK integrations as the codec moves out of its initial beta phase.

ARRI's ARRICORE launch positions the company against a growing field of camera manufacturers pursuing in-camera compression that preserves RAW-like flexibility. At NAB Show 2025, Sony announced that its VENICE 2 camera system would support a new X-OCN LT codec mode that reduces data rates by approximately 30 percent compared to its standard X-OCN format while retaining 16-bit linear color information. RED Digital Cinema, now under Nikon ownership, introduced REDCODE RAW compression ratios up to 22:1 on the V-RAPTOR XL X in early 2025, targeting documentary and unscripted workflows where storage logistics dominate budgets. ARRI's 50 percent reduction claim for ARRICORE is notably aggressive relative to these competitors, though the trade-off of moving debayering into the camera hardware rather than preserving a true sensor-native RAW file represents a philosophical difference in workflow design.

The business implications for post-production facilities and rental houses are significant. Codex, which manufactures the Compact Drives used in ALEXA systems, announced a 4TB Compact Drive variant in March 2025 specifically to address the storage demands of high-frame-rate RAW capture. With ARRICORE halving data rates, a single 4TB drive could theoretically store approximately twice the footage compared to ARRIRAW at equivalent frame rates, reducing media costs for productions shooting at 660fps. Picture Shop, a leading dailies and post-production service provider, confirmed in July 2025 that it had begun beta testing ARRICORE decoding pipelines across its Los Angeles and London facilities, with colorist Peter Doyle noting that the codec's REVEAL Color Science integration allowed grading workflows to remain consistent with existing ARRIRAW projects.

Independent technical validation of visually lossless claims remains an open question for the broader industry. The American Society of Cinematographers' Technology Committee published a framework in late 2025 for evaluating perceptual transparency in camera-originated codecs, establishing criteria that include side-by-side comparison at 4:1 pixel magnification and statistical analysis of color volume preservation. ARRI's Charles Bergquist, who leads the company's camera system engineering division, presented ARRICORE's internal validation methodology at IBC 2025, reporting that across 12,000 test frames no trained observer could distinguish ARRICORE-encoded footage from ARRIRAW originals in controlled viewing conditions. The codec's reliance on in-camera debayering means that third-party tools like DaVinci Resolve and Baselight will need updated SDKs to decode ARRICORE natively, a dependency that could influence adoption timelines among post houses that have standardized on ARRIRAW pipelines.
