The film is scanned using the full sensor area of 4096x3072 to keep the audio
waveform visible for optical audio and to accommodate perforation visibility for
stabilization. The image is then cropped and the resolution of the capture files
depends on the source film format after overscan for perforations and the audio area
are removed. For more information about scanning resolutions for different types of
film, see the 'specifications' section.
The Cintel scanner creates Cintel Raw files with variable bitrate lossless compression
by default. This is visually lossless compression and achieves approximately 3:2
reduction in file size depending on image content. However, Cintel Raw 3:1 uses lossy
compression with a ratio of approximately 3:1. This is still very high quality but may not
always be visually lossless. For example, files for 35mm 4 perf are approximately
12.5MB with Cintel Raw and approximately 6.3MB with Cintel Raw 3:1. Files for 16mm
are approximately 4MB with Cintel Raw and approximately 2MB with Cintel Raw 3:1.

CinemaDNG Quality Settings

To control the quality of CRI files, use the 'decode quality' and 'play quality' CinemaDNG
settings located in the Camera Raw panel of the project Settings. These settings are 'full'
by default. On computers with low processor or memory resources, these settings may be
lowered but this will affect the quality of the final render.

Set the Timeline Resolution

DaVinci Resolve displays and renders the output from the scanner using the same resolution
as the timeline. For example, for 35mm 4 perforation film, a custom resolution of 4096x3072
would be required for maximum resolution.
For more information on the cropped image area resolutions for all film gauges, refer to the
'effective resolutions' in the 'specifications' section. Alternatively, for the full native resolution of
the captured clip, access the 'clips attributes' in DaVinci Resolve.

Adjusting the Color of the Scanner

DaVinci Resolve's film scanner panel gives you control over the exposure and color
temperature of the light used to illuminate the film for scanning. You can adjust these via the
light source master wheel and RGB controls, in order to maximize the amount of information
you're extracting from each frame, while preventing any part of the image from being
irretrievably clipped. While it's true that CRI is a raw image format, there's no latitude beyond
the internal data range used by DaVinci, so be mindful that if you're clipping data in the built in
video scopes while scanning, it might be clipped permanently in the scanned media.
How often you'll adjust the color and exposure of scanned shots depends on how much variety
there is in the scenes on a particular film roll. For example, some rolls may have many takes of
the same scene, all of which have the same lighting and which can share the same adjustments.
Meanwhile, other rolls may have a variety of different scenes with widely different lighting in
each one, necessitating you to make individual adjustments for each scanned clip to maximize
data quality.
