The Academy Color Encoding System (ACES) is a set of components that facilitates a wide range of motion picture workflows while eliminating the ambiguity of today's file formats. The framework is designed to support both all digital and hybrid film-digital motion picture workflows.

The basic ACES components are:

• Color encoding and metric specifications, file format specifications, color transformations, and an open source reference implementation.
• A set of reference images and calibration targets for film scanners and recorders
• Documentation on the architecture and software tools

This toolkit is intended to serve as a distribution mechanism for key components of the framework including the reference implementation transforms, reference images, and documentation.

• documents/ - ACES related documents
• images/ - "golden" images created using the reference implementation transforms
• transforms/ - ACES reference implementation transforms

For a detailed list of changes see the CHANGELOG.

The links to the current and all past versions of the ACES Developer Resources can be found at https://github.com/ampas/aces-dev/releases.

Source code is version controlled using the git version control system and hosted on Github at https://github.com/ampas/aces-dev/.

Master Branch

The current release version of ACES can always be found at the HEAD of the master branch. Previous release versions are tagged and are also commits on the master. The master branch contains no intermediate commits so all commits on the master branch are tagged and represent a release of ACES.

Dev Branch

All commits between releases will be on the dev branch. Commits on the dev branch will be included in the next release version. Commits staged on the dev branch, but not yet merged into the master, should be considered non-critical. All intermediate commits for a release will be staged on the dev branch before being merged into the master and tagged.

Hotfixes Branch

In some cases it may be necessary to create a hotfixes branch. The hotfixes branch will include important, but not fully tested, fixes for bugs found in a particular release. Hotfixes should only be implemented by developers if the bug they are intended to correct is encountered in the course of production and is deemed to be a barrier to using a particular ACES release. Hotfixes, once fully tested, will be merged into dev branch, and ultimately the master.
