Sensor Readout Size for ProRes 2K Recording
When the camera is switched from HD to 2K resolution in-camera recording, the size of the captured frame changes slightly. This is necessary, so the debayering can work with an optimized downscale factor and deliver the best possible 2K image quality.
• Recording ARRIRAW 16:9, HD-Video, ProRes HD and DNxHD uses 2880 x 1620 photosites with a frame size of 23.76 x 13.365 mm.
• ProRes 2K 16:9 uses 2868 x 1612 photosites (23.661 x 13.299 mm).
• ARRIRAW 4:3 uses 2880 x 2160 photosites (23.76 x 17,82 mm).
• ProRes 2K 4:3 uses 2868 x 2150 photosites (23.661 x 17,738 mm).
When recording ARRIRAW and ProRes 2K in parallel, it is important to note, that the ARRIRAW frame holds a few more columns and lines of pixels. This is taken into account in the latest release of our ARRIRAW SDK, where the user can select, which ARRIRAW frame size will be used to create a 2K image.
