Safari preferences shaded on imac1/9/2024 ![]() For example, with television, it was determined long ago that the stronger contrast and darker shadows of gamma 2.4 looked best because most people watched TV in dimly lit rooms. Gamma values are different between computers, televisions and movie theaters so images look their best in each environment. As you can see, the higher the gamma numerical value, the darker and more contrasty the image. How do these gamma values affect photos and videos? Here are some helpful images published by display manufacturer BenQ. Broadcast television uses gamma 2.4, while pretty much anything that’s not a television uses gamma 2.2. Gamma 2.6 is high contrast with deep, dark shadows. Common Display Gamma Valuesįilms created for theaters typically use gamma 2.6 (the lowest curve in the chart above). Think of gamma as a Tone Curve, with pure black at lower left, pure white at upper right, and shades of gray in between. Here’s an illustration of the most commonly used gamma values. Gamma is a mathematical way of quantifying contrast on a display. So all that said, what in the world is going on here? Why is this a problem in macOS, but not other operating systems? To answer that, we need to take a closer look at display gamma. This option would be most useful when screening videos for clients, sharing videos with other macOS users, displaying video as part of a presentation from a MacBook, or other situations where the video will be viewed using macOS. If you are exporting a video that will be viewed only on a Mac - your display, a client’s display, etc - and not live online for months or years to come, then it may make sense to apply Adobe’s Gamma Compensation LUT or add your own extra contrast adjustment. Also, if Apple were to fix the problem at some point in the future, all your past videos exported without a LUT or contrast adjustments would then display correctly in macOS. ![]() Yes, it is annoying seeing slightly more washed out video in macOS, but then you aren't optimizing your video for one audience at the expense of everyone else. If this is what you are currently doing, you don’t need to change anything with your workflow. If you are exporting video anyone may see at any time on any display, the simplest and safest bet is exporting video from Premiere normally, without LUTs or contrast adjustments. It depends on whether your video will be seen by everyone (eg, YouTube) or only those using macOS. Or, to be more precise, you may apply the ASC CDL Color Correction effect to the adjustment layer, then set its Red, Green, and Blue Power settings to 1.09.Įxported video will then appear more similar to your Premiere color grade, but won’t look as dark as Adobe’s aforementioned LUT. If you'd like to split the difference and export a video that looks a little better in macOS, but without being too dark in Windows, you may add extra contrast using an adjustment layer and Lumetri color at the top of your Premiere timeline. Option three: Add contrast to the Premiere Timeline with an Adjustment Layer This will however create a darker video when viewed using Windows or any non color managed macOS application. I’ll explain how this LUT works in a minute, but for now, this is a simple LUT that changes the contrast of exported video to appear "correct" when viewed using QuickTime, Chrome, Safari, or any color-managed macOS application. ![]() Option two: Export gamma-corrected video for viewing on a MacĪdobe offers a free QuickTime Gamma Compensation LUT. ![]() Simply export as you normally would and move on. Mac users will see a slightly softer, less contrasty image, but videos never look the same on every screen anyway, so there is no silver bullet to fix this issue. As long as you’re happy with your color grade, and like how your video looks inside Premiere, you may rest assured your exported video will appear as expected on the majority of televisions and computer displays out there. ![]() Simply export h.264 video from Premiere and use it as is. Why does this happen? And what can you do about it? I'll explain what's going on in a minute, but here are three options macOS users should consider when exporting video from Premiere. This is known as the dreaded “QuickTime Gamma Shift”, and it unfortunately affects anyone currently editing video using Adobe Premiere Pro on a Mac. If you edit video using Adobe Premiere Pro on a Mac, chances are you’ve encountered a problem where exported video looks washed out and desaturated in QuickTime Player, Safari and Chrome when compared to the same video viewed inside Premiere on a timeline. ![]()
