Many high-profile movies have been shot in ARRIRAW 2.8K and up-sampled to a 4K DCP with spectacular results, an example being the last James Bond film, Skyfall . To further improve upon this option, ARRI introduced the ARRIRAW Open Gate recording format for ALEXA XT cameras. Open Gate records the full 3.4K ALEXA XT sensor area for an optimal up- sample in post to a 4K DCP. Open Gate has been enthusiastically received by the feature film industry and is in use on numerous productions already, including Warcraft, San Andreas, Pixels, Goosebumps and Sicario , the latest movie lensed by Roger Deakins, CBE, ASC, BSC. Other feature films are shooting ARRIRAW 16:9 or ARRIRAW 4:3 and using Open Gate selectively for VFX shots, including Terminator: Genesis, Fantastic 4, Agent 47 and Deus Ex Machina. CAPTURE WITH ALEXA, DELIVER 4K FOR FEATURE FILMS Recent demonstrations of high dynamic range (HDR) displays have shown the extraordinary visual impact of increased dynamic range and sparked a debate over how and when they will be introduced. ARRI has been working with Dolby at major trade shows to help showcase Dolby®Vision™ display technology, which is capable of 100 times more brightness than a conventional TV. This has contributed to spreading awareness in the industry that dynamic range is an even more important factor than spatial resolution in creating a superior visual experience. Recognizing this, other companies such as Thomson, CAPTURE WITH ALEXA, PROTECT FOR HDR Philips and the BBC are working on their own HDR solutions. ALEXA's unrivalled exposure latitude, highlight handling and color science already result in images beyond the capabilities of current display technologies. The Dolby® Vision™ presentations have revealed how much better ALEXA images look when displayed with extended dynamic range, proving the enormous and as-yet untapped potential of ALEXA-originated material to be remastered for future HDR display standards. “ProRes 3.2K gives ALEXA customers greater workflow flexibility than they've ever had before.” Michael Cioni, founder and CEO of Light Iron Sensor Mode Recording Format Format Settings 16:9 ProRes HD 422 422 HQ 4444 4444 XQ ProRes 2K 422 422 HQ 4444 4444 XQ ProRes 3.2K 422 422 HQ 4444 4444 XQ DNxHD 145 220x 444 ARRIRAW 4:3 ProRes 2K 422 422 HQ 4444 4444 XQ ARRIRAW Full Cropped Open Gate ARRIRAW ALEXA XT Recording Formats Overview For TV productions looking for a UHD deliverable, ALEXA XT cameras and ALEXA Classic cameras with the XR Module upgrade offer the new and cost-efficient ProRes 3.2K recording option. At data rates far below uncompressed ARRIRAW, ProRes 3.2K provides the benefits of the well-established and efficient ProRes workflow. As an additional benefit, most lenses fully cover the 3.2K image circle that results from the 16:9 ProRes 3.2K image. A straightforward up-sample from ProRes 3.2K using standard post tools delivers UHD images of the highest quality for broadband and broadcast.
