Besides which, scores of high math ability do not in fact particularly associate with gating an eng/science major for men; the barrier to entry to these majors is quite low for men, achievement-wise.

Masterclass: โ€œColourspaces in D-cinema, ACES, and Streamingโ€

Vancouver, Sat Dec 13, 09:30โ€“17:30.
Presented by Charles Poynton, PhD
Organized by VPA and VES Vancouver
Hosted by Elemental Post

Weโ€™ll explore the theoretical and practical aspects of colourspaces commonly used in production, VFX/CGI, post-production, and presentation of movies, broadcast, streaming video, and games.

VPA, VES Members: $315
Non-Members: $350

Charles Poynton Masterclass: Colourspaces in D-cinema, ACES, and Streaming

In this one-day masterclass, we unpack the colourspaces that drive todayโ€™s professional imaging pipelines โ€“ from camera and VFX working spaces through grading environments to final delivery in cinema, broadcast, UHD/HDR/WCG, and streaming. Weโ€™ll connect the dots between Rec.709/BT.1886 SDR monitoring, theatrical P3 grading, Rec.2020 (BT.2020) wide-gamut UHD delivery, and metadata-driven HDR formats such as Dolby Vision.Why are there so many colourspaces in digital cinema/UHD/HDR/WCG/streamingย pipelines?Weโ€™ll break down the distinct requirements โ€“ and colourspaces โ€“ used at each stage:โ€ข Colourspaces for cameras & VFX/CGIโ€ข Colourspaces for grading and look developmentโ€ข Colourspaces for distribution (P3 theatrical, Rec.709/BT.1886 SDR, Rec.2020 HDR)โ€ข Colourspaces for presentation/display, including HDR10, HLG, and Dolby VisionYouโ€™ll see how scene-referred camera spaces and ACES working spaces are transformed intoย display-referred deliverables for:โ€ข D-cinema masters in P3 (typically P3-D65 or P3-DCI)โ€ข Broadcast and streaming SDR in Rec.709 with a BT.1886 (โ‰ˆ2.4) EOTFโ€ข UHD/HDR streaming that often uses P3 primaries in a Rec.2020 container with PQ or HLG transfer functions, including Dolby Vision trims and metadata.Who this masterclass is for:โ€ข Cinematographers & DITsโ€ข Colourists & colour assistantsโ€ข Studio colour scientistsโ€ข VFX supervisors & colour-pipeline TDsโ€ข Post-production supervisorsโ€ข Lighters, shaders, look developersWhat youโ€™ll learn:Weโ€™ll explore both the theoretical and practical aspects of the colour spaces most commonly used in production, post-production, and presentation of movies, broadcast, streaming video, and games. You will:โ€ข Understand why the requirements at capture, grading, and delivery are different, and how the transforms among camera, ACES, P3, Rec.709, and Rec.2020 spaces are managed.โ€ข Gain a deep understanding of power-function (โ€œgammaโ€) and logarithmic/quasi-log (โ€œlogโ€) encoding, and how they relate to BT.1886 (2.4) and 2.6 gamma reference environments.โ€ข Learn how OpenEXR, CTL, ACES, and OpenColorIO are used to implement and standardize transforms between scene-referred and display-referred colourspaces.โ€ข Understand the implications of sRGB, 2.2, 2.4 (BT.1886), and 2.6-gamma viewing for SDR monitoring, and how they contrast with HDR10, PQ, HLG, and Dolby Vision HDR workflows.โ€ข Appreciate why video in distribution is always display-referred โ€“ even when the upstream pipeline is scene-referred โ€“ and what that means when mastering for P3 cinema, Rec.709 SDR, and Rec.2020/PQ or Dolby Vision HDR deliverables.Lots of graphs and equations will be shown and explained. If you have first-year university math,ย youโ€™ll be able to dive deeply into log coding, the CIE chromaticity diagram, and the geometry of colour gamuts such as P3 and Rec.2020. If your background is high-school math, weโ€™ll still cover the necessary fundamentals, so you come away with a solid working understanding of modern colourspaces and HDR/SDR systems.About Charles PoyntonCharles Poynton, PhD, is an independent researcher in image and colour science based in Toronto, Canada. He specializes in the physics, mathematics, engineering, and algorithms of digital colour imaging systems, with particular focus on digital cinema, HDR/WCG, and modern distribution systems such as Dolby Vision and HDR streaming platforms.

What I'm listening to today: "the 3rd experience", Merr0w

Behold the unbelievable versatility of the Roland TB-303, released in 1981 as a bass accompaniment device for guitarists, failed rapidly as it doesn't actually work for this, postmortem birthed multiple genres of music and decades later there's a whole micro-industry of clone devices and folks are still creating fun unique-feeling music with them. Here's some acid trance (is this "goa"?). This is the sound. This

RE: social.edu.nl/@Bibliothecaris/

Over the moon that we (finally) did this!

๐ŸŽ‰ We're the first department at the @universityofgroningen to adopt , and I hope others will follow.

Next step: Exploring how we can embed PeerTube videos into our university's CMS.
