Teaching Daily Routines

One of the twenty-eight classes I teach each week in Ho Chi Minh City. I consider myself lucky, since many foreigners had to leave the country because of tightened restrictions on visas or loss of employment opportunities, including a large community of Ukranians.

Create Textural Depth II

The viewer’s eye can be drawn to the subject in a number of ways. Two of the techniques employed here are color separation, achieved through split-toning, and obscuring the surroundings using a mask and reducing brightness. Another approach is to create textural depth by accentuating the texture in cooler, darker backgrounds while de-emphasizing grain in... Continue Reading →

Projector Central Weighs in on 4:2:0

Over at Projector Central, Michael J. McNamara, former Executive Technology Editor of Popular Photography magazine and a renowned expert on digital capture, storage, and display technologies writes:  “Does using 4:2:0 subsampling significantly degrade image quality for movie viewing versus using 4:2:2? Not according to most viewers who've enjoyed any number of 4K UHD SDR and... Continue Reading →

Create Textural Depth!

During an appearance on Cullen Kelly’s Grade School, the brilliant colorist Jill Bogdanowicz revealed a secret to accenting texture without it looking over-processed. While working on Joker, the colorist used Live Grain - which separates out the red, green and blue channels, creating grain that resembles scanned film - to accentuate texture in the cooler,...

Not A Grade Reveal!

A few caveats: first, the original footage was green and overexposed; secondly, we didn't use the recommended DaVinci Wide Gamut; and lastly, as we do all of our grading before the LUT, the original footage looked nuts when we removed the LUT for the grade reveal, so we normalized it for the video. https://youtu.be/3Bv3RUGbwEc

Massive LUTs Required for HDR

According to at least one study, in order to achieve a comparably error-free 3D-LUT to those used for SDR, a LUT size larger than 55x55x55 is required for 12-bit HDR (Rec.2020 ST2084). Of course, such gargantuan LUTs aren't currently feasible! "In 10-bit SDR, in order to achieve unnoticeable interpolation errors using the trilinear interpolation method,... Continue Reading →

Cullen Kelly’s Kodak 2383 LUT + DL

The aggressive compression algorithms of streaming platforms destroy grain, which is why we don’t upload videos with grain to YouTube. Instead, we’re offering subscribers the opportunity to download clips, allowing you to view the picture as it was intended. We recommend throwing the movie on the timeline of your favorite NLE, setting the project to... Continue Reading →

Apple’s Studio Display Unsuitable for Video Editing

Author, consultant, pro audio/video specialist, tech journalist and broadcaster Allan Tépper voices his suspicions that Apple’s Studio Display is not a true 10-bit panel at all but 8-bit FRC and discovers that it is limited to a single framerate/refresh rate, making it a much less attractive proposition for video editing/grading. “Despite it’s raved internal speakers...
