1 Definitions of 4k and Extended Dynamic Range October 7 th, 2014

2 Sony Pictures has established the following policy with respect to high quality image characteristics, 4K terminology and extended dynamic range: To be considered 4K a title must be acquired either on film (35mm or 65mm), and scanned at 4K (or higher) resolution, or with an industry accepted 4K (or higher) digital camera as the primary source, and must be finished/mastered in a true 4K workflow. The camera must have at least 4096 photosites across the sensor, with at least half of those (2048) dedicated to the green channel. If camera file processing software (de-Bayering or other) is deployed, the system must be capable of decoding images directly to 4K or better resolution from the original Bayer pattern (or other pixel format) with no further pre-processing. Where applicable, the 4K workflow will have the output format as a 4K raster and will use the 4K master source for all shots, and any 2K VFX should be created from 4K master source. Sony Pictures defines extended dynamic range as both expanded color gamut (greater than Rec.709) and high dynamic range, maintaining highlight detail and lowlight/deep shadow detail (7 stops over/under middle gray). For high quality imaging, the primary camera must be capable of capturing a color gamut of P3 at a minimum, and a dynamic range of 14 stops (or better) in order to support extended dynamic range mastering for cinema and home delivery systems. A true high quality finishing workflow should be capable of generating a 16bit 4K (4096) or UHD (3840) digital source master with expanded color gamut as the primary deliverable. The 4K finishing workflow should also include capability for extended dynamic range mastering in the near future.

3 DEG The DEG is finalizing a set of definitions to describe 4k content: – 4K IC (Image Capture) - motion pictures and television programs shot on digital cameras with 4K or larger sensors. – 4K FS (Film Scans)- 35mm or other films that have undergone 4K or 8K scanning to create a new production master. – 4K CG (Computer Generated) - Animation or special effects that have been rendered on workstations at 4K resolution. – 4K UC (Upconverted Content) - HD content that undergoes an upscaling process that enables it to be displayed in 4K. SPE needs a term consistent with our definition of 4k to describe up-scaled 2k/HD content.

4 4k Acquisition – Spherical Lenses 4k Sony F65 Sony F55 Arri 65 Red Epic and Red Dragon – When configured to shoot 4k or greater 35mm and 65mm film scanned at 4k Black Magic Ursa Phantom Flex 4k Not 4k Arri Alexa and Amira – All models including Alexa XT, open gate configuration and Amira 4k upscale in camera Sony F35, F25, F900, F3 Panavision Genesis Red One Any HD video camera 16mm film – Regardless of scan resolution

5 4k Acquisition – Anamorphic Lenses 4k* Sony F65 de-bayered at 6k or 8k Red Dragon de-bayered at 6k Arri 65 de-bayered at 6k 35mm and 65mm film scanned at 4k Not 4k Sony F55 Red Epic Black Magic Ursa Phantom Flex 4k Any >4k camera de-bayered at 4k *Anamorphic lenses on super 35 cameras use 67% of the sensor width therefore these cameras must be debayered at 6k or 8k.
