ACES (Academy Color Encoding System)

ACES (Academy Color Encoding System) is a color management framework developed by the Academy of Motion Picture Arts and Sciences to provide a single, device-independent color pipeline from camera capture through visual effects, color grading and final delivery. At its core sits ACES2065-1 (also called AP0), a wide-gamut linear scene-referred color space that exceeds the visible spectrum and serves as the archival exchange format. Working color spaces ACEScg (linear, used for VFX rendering), ACEScct (logarithmic, used for grading with a small toe for shadow control) and ACEScc (purely logarithmic, used for grading) sit inside the pipeline for specific tasks. Transformations are managed by IDTs (Input Device Transforms, one per camera), the RRT (Reference Rendering Transform, a shared global tone mapper) and ODTs (Output Device Transforms, one per delivery format such as Rec.709, P3-D65, Rec.2020 PQ). The ACES pipeline solves the recurring industry problem of inconsistent color between cameras, VFX vendors and grading suites, by mathematically defining every conversion. Major studios mandate ACES delivery for tentpole features (Marvel, Netflix Originals, A24 productions all require it). Free reference implementations exist (OpenColorIO ACES configs) and DaVinci Resolve, Baselight, Nuke, Flame all support ACES natively.
