Colourspaces in D-cinema, ACES, VFX/CGI, and Streaming

Colourspaces in D-cinema, ACES, VFX/CGI, and Streaming

The National Talent Academy for VFX is excited to host this 1 day masterclass presented by independent researcher Charles Poynton.

Why are there so many colourspaces in digital cinema/UHD/HDR/WCG/streaming pipelines?

  • Colourspaces for cameras & VFX/CGI
  • Colourspaces for grading
  • Colourspaces for distribution
  • Colourspaces for presentation/display

In this masterclass, we’ll explore the theoretical and practical aspects of colourspaces commonly used in production, post-production, and presentation of movies, broadcast, streaming video, and games. You’ll learn why the requirements at each stage are distinct, and you’ll gain an understanding of the transforms among them. By the end of the day, you’ll have a deep understanding of power function (“gamma”) and logarithmic/quasilog (“log”) encoding. You’ll learn about the OpenEXR, CTL, ACES, and OpenColorIO approaches to transforms among these colourspaces. You’ll understand the implications of sRGB, 2.2, 2.4, and 2.6-gamma for SDR display, and the HDR10, PQ, and HLG standards for HDR. You’ll appreciate why video in distribution is always display-referred (despite some proponents claiming that their distribution encoding is scene-referred).

Lots of graphs and equations will be shown and explained. If you have first-year university math: great! You’ll gain a deep understanding of log coding and the CIE chromaticity diagram, among other things. However, we’ll address the necessary math fundamentals during the day; if you have high-school math, you’ll come away with a good understanding of colourspaces.

    Charles Poynton

    Charles Poynton is an independent researcher and image/colour scientist based in Toronto. He wrote the book Digital Video and HD Algorithms and Interfaces, now in its second edition. Thirty five years ago, he chose 1080 image rows for HD standards, by which “square pixels” were established for HD and digital cinema. He earned his PhD in 2018 from Simon Fraser University with a dissertation entitled Colour Appearance Issues in Digital Video, HD/UHD, and D cinema. He is a Fellow of SMPTE, Colorist Society (CSI), and IMIS (formerly BKSTS).
