What is ACES?
The Academy Color Encoding System (ACES) is the industry standard for managing color throughout the life cycle of a motion picture or television production. From image capture through editing, VFX, mastering, public presentation, archiving and future remastering, ACES ensures a consistent color experience that preserves the filmmaker’s creative vision. In addition to the creative benefits, ACES addresses and solves a number of significant production, post-production, delivery, and archiving problems that have arisen with the increasing variety of digital cameras and formats in use, as well as the surge in the number of productions that rely on worldwide collaboration using shared digital image files.
ACES is a free, open, device-independent color management and image interchange system that can be applied to almost any current or future workflow. It was developed by hundreds of the industry’s top scientists, engineers and end users, working together under the auspices of the Academy of Motion Picture Arts and Sciences.
ACES 1.0 was the first production-ready release of the system, the result of over 10 years of research, testing and field trials. It includes support for a wide variety of digital and film-based production workflows, visual effects, animation, final delivery and archiving. The most current release version, ACES 1.2, clarifies some specifications and addresses a few user-generated comments and requests and is being widely used around the globe. ACES 2.0, currently in development, will simplify and add support for additional workflows. It is being created using our open and transparent ACESNext Virtual Working Group development process and is expected to be available in 2021.
WHAT PRODUCTIONS HAVE USED ACES?
There have been many significant and successful uses of ACES in motion pictures, television, documentaries, commercials and even VR. For a partial list of motion picture and television productions, please visit ACESCentral.com
What problems does ACES 1.2 solve?
Today’s motion pictures and television shows are complex collaborative efforts, involving many separate companies using digital image capture, image creation and editorial workflows that are much more difficult to integrate than film-based workflows.
On a typical production there might be half a dozen different digital cameras as well as a film camera in use, all recording to different devices and media using different data formats. During post-production, especially on major motion pictures, multiple facilities may be engaged for editing, visual effects, mastering and other work. Digital image files arrive at these facilities in any of a dozen (or more!) formats and color encoding schemes, often without essential metadata. At the end of the process, studio deliverables could range from large-screen film prints to mobile device encodings.
All along the way, the integration challenges increase – and on the horizon there are undoubtedly emerging technologies and new all-digital distribution platforms that will add complexities of their own.
ACES 1.2 solves numerous integration challenges by enabling consistent, high-quality color management from production to distribution. It provides digital image encoding and other specifications that preserve the latitude and color range of the original imagery, allowing the highest-quality images possible from the cameras and processes used. Equally important, ACES 1.2 establishes a common standard so deliverables can be efficiently and predictably created and preserved. ACES 1.2 enables filmmakers to manage the look of a production today and into the future.
What are the benefits of ACES 1.2 for specific users?
Virtually everyone involved in production, post-production and archiving can enjoy ACES benefits.
For cinematographers, colorists and digital imaging technicians, ACES 1.2 preserves creative intent from on-set capture to presentation by:
- Eliminating uncertainty between on-set look management and downstream color correction through standardized viewing transforms and equipment calibration methods
- Preserving the full range of highlights, shadows and colors captured on set for use throughout post-production and mastering
- Simplifying the matching of images from different cameras
- Providing a means to repurpose source materials when creating alternate deliverables
For visual effects and other post-production facilities, ACES 1.2 streamlines digital workflows by:
- Simplifying the interchange of unfinished motion picture imagery
- Providing a standard color management architecture that can be shared by hardware and software vendors
- Eliminating uncertainty associated with undocumented or poorly documented file formats and color encodings
- Establishing standards for metadata
For producers and studios, ACES 1.2 reduces production costs and enables future-proofed archiving by:
- Providing a free, open source color and look management architecture that can be shared by vendors whose hardware and software products are used on set and in post-production
- Ensuring digital assets can be repurposed to take advantage of future high-dynamic-range, wide-color-gamut display devices
- Ensuring the archive contains the highest fidelity digital source master possible, representing the digital equivalent of the “finished negative”

What is the ACES Logo Program?
The ACES Logo Program seeks to further the adoption of ACES throughout all segments of the industry. The Program initially focuses on production and post‐production equipment and tools (“Product Partners”) because without consistent, high‐quality ACES support in products, facilities and productions cannot benefit from ACES. Future enhancements to the Logo Program will cover facilities ("Service Partners") such as dailies providers, VFX studios, DI and mastering facilities. Eventually, the Program may include the ability for actual motion picture and television productions to earn a Logo (i.e. an ACES ‘bug’ at the end of a movie.)
The ACES Logo is a signal to end-users and filmmaking professionals that a Logo’d product or service meets the Logo Program qualification criteria and this should translate into a more satisfying ACES experience when part of a properly configured ACES color-managed workflow.
The 31 companies listed below are supporting ACES adoption, as Product Partners and by building ACES support into one or more of their products.
To become an ACES Product Partner, please review the application process and submit your application if your company meets Program requirements.
