User Manual

For more information on how color management affects the Fusion page, and why the Linear
color space is preferable for compositing, see Chapter 67, “Controlling Image Processing
and Resolution.”
Exporting Color Space Information to QuickTime Files
If you render QuickTime files from the Deliver page, then color space tags will be embedded
into each file based on either the Timeline Color Space (if Resolve Color Management is
disabled) or the Output Color Space (if Resolve Color Management is enabled). The following
tags will be written, if currently selected:
REC 709
REC 2020
REC 2021
CIE XYZ
P3DCI
P3D60
Color Management Using ACES
The ACES (Academy Color Encoding Specification) color space has been designed to make
scene-referred color management a reality for high-end digital cinema workflows. ACES also
makes it easier to extract high-precision, wide-latitude image data from raw camera formats,
in order to preserve high-quality image data from acquisition through the color grading process,
and to output high-quality data for broadcast viewing, film printing, or digital cinema encoding.
An oversimplification of the way ACES works is that every camera and acquisition device is
characterized to create an IDT (Input Device Transform) that specifies how media from that
device is converted into the ACES color space. The ACES gamut has been designed to be large
enough to encompass all visible light, with more than 25 stops of exposure latitude. In this way
ACES has been designed to be future-proof, taking into consideration advances in image
capture and distribution.
Meanwhile, an RRT (Reference Rendering Transform) is used to transform the data provided by
each image format’s IDT into standardized, high-precision, wide-latitude image data that in turn
is processed via an ODT (Output Device Transform). Different ODT settings correspond to each
standard of monitoring and output, and describe how to accurately convert the data within the
ACES color space into the gamut of that display in order to most accurately represent the image
in every situation. The RRT and ODT always work together.
