Meet ACES, the Professional Color Management Standard for the Digital Age

The dizzying array of digital media formats for capture, playback, and distribution is, well, overwhelming at the very least. And you'd better believe that there's never been a truly standardized system of managing color throughout the entirety of a post production pipeline. Until now.

So what exactly is ACES? Well, for starters it's an acronym for Academy Color Encoding System. In essence, ACES provides filmmakers with "a free, open, device-independent color management and image interchange system that can be applied to almost any current or future workflow." Now officially in its version 1.0 release, ACES is aiming to become the industry standard for digital color management throughout all aspects of image the image pipeline, from image capture to editing, VFX, mastering, presentation, archiving, and future remastering.

You're probably wondering who ACES is for, and how it can help filmmakers of with their work. Here's the Academy breakdown:

ACES Color Encoding

For cinematographers, colorists and digital imaging technicians, ACES 1.0 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 1.0 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 1.0 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? What is it? A Codec? a color correction software? A Lut? Explain....

Its not a standard yet.
Its basically an idea w/ a lot of support behind it,
its available for testing in some production cameras, RED included.

My understanding is that SMPTE has to approve it as a standard.
Where they are in that process, I don't know.

It is a high resolution color space/standard designed to replace what we are currently using (multiple standards -rec709, dci, srgb- based on the output). One advantage to working in Aces is you can utilize transform nodes provided by the manufacturer to bring images shot at different color spaces (such as logc or slog) into a high res linear color space. This would be more accurate than a lut to rec709 and would not incur the same clipping. The concept is to make grading easier once all images are in a linear color space (you can apply grades from different cameras to each other with minimal differences between shots).

In addition, establishing a standard from hardware to software should make calibrating monitors easier if everything is coming from the same color space. Your limitations would be only hardware, not hardware and color space you are outputting.

Finally, Aces is a huge color space, meaning archival of a project will keep as much color information from your camera as possible.

thanks for the explanation. I couldn't finish watching the interview because the interviewer is so painful to watch.

Every camera manufacturer will have to open their codec's to ACES for the input transform when ingesting footage into whatever grading application you are using otherwise the info will be off. Resolve I think has most of the major camera input transforms I believe. I may be wrong.

I seriously have no idea what this is after watching that interview

A very basic explanation is that it takes the flat images coming from most cameras these days and makes them look good right off the bat and is a better place to start coloring. Also, it handles the color sciences between cameras (input) and displays (outputs) and allows you to match cameras and grade once and then switch displays such as Rec709 (TV) and DCI-P3 (Theatrical). So, in a program like Resolve, you set your color science to ACES, select all the right IDT (Input Transforms) for your various cameras, and select your display ODT (Output Transform) and you can start coloring from a solid starting point. With a few cameras now, you can go ahead and view it this way on set too. Explanations are tricky but it makes coloring easier, faster, and higher quality.

It's amazing that a standard for video colour management still doesn't exist but if this works out and gets adopted it's going to make life SO much easier. Good luck to them.

It's free and it's currently inside Davinci Resolve, that is an old video, now there are more camera options, SLOG2, SLOG3 in XAVC are supported for instance.
