[18:27 Tue,1.September 2026 � by Thomas Richter] ���
Tomorrow evening, September 2nd, ARRI is hosting a free live webinar titled "Exploring ARRICORE: A Visually Lossless RGB Codec," in which DP Charles Bergquist, along with Picture Shop's Supervising Colorist Peter Doyle and Senior Colorist Frederik Bokkenheuser, will discuss the applications of ARRICORE, the RGB codec developed by ARRI. The main focus will be on the practical benefits of ARRICORE in everyday shooting and post-production routines—with a particular emphasis on color grading—and how it compares to ARRIRAW. The webinar will take place online at 9:00 PM German time, and registration via Zoom is required.
The Panel of Experts
The three panelists of the webinar are professionals from the film and commercial sectors. According to ARRI, Supervising Colorist Peter Doyle is one of the industry's most influential colorists and is known for developing innovative techniques and distinctive looks for major studio films such as Creed III, Darkest Hour, Edge of Tomorrow, and Wrath of Man, as well as visually ambitious projects like The Tragedy of Macbeth, Cyrano, Inside Llewyn Davis, and the award-winning series Disclaimer. Senior Colorist Frederik Bokkenheuser brings extensive experience in high-end episodic formats and documentary productions to the discussion; his credits include M.I.A., The Rookie: Feds, Netflix’s Archive 81, Elton John: Never Too Late, and BTS: The Return.
What is ARRICORE?
ARRICORE is a compressed, pre-debayered RGB codec, which ARRI introduced alongside the ALEXA 35 Xtreme. Unlike ARRIRAW, and according to ARRI, it delivers a data rate that is about 50 percent lower with "visually lossless" quality as claimed by the manufacturer, putting it slightly below the data rate of ProRes 4444 as well—while offering double the recording time and half the download time compared to ARRIRAW. Furthermore, editing and grading software can directly decode a proxy resolution instead of full resolution, which is intended to enable faster thumbnails and previews.
