It interprets the metadata information embedded in video files through the Display Profile. Apple’s ColorSyncĪpple’s software ColorSync uses metadata to match image or video color between various applications. Apple created ColorSync to address this very issue. This is why there can be a disconnect between applications for how colors are displayed. However, most post applications don’t use Apple’s display profile by default since most of them still work in a rec709-type color space. Since Apple displays have their own color space profile, video files need to be somehow translated into this space to be viewed properly. There isn’t a Display P3 deliverable spec like there is for rec709 (broadcast) or DCI-P3 (feature film.) If you don’t understand any of that, that’s fine.Īll that it means is that Apple’s default color profile is it’s own beast. Also, Apple’s P3 has a transfer function or gamma that is sRGB as opposed to the 2.6 gamma of DCI-P3. Apple’s P3 has a D65 white point while DCI-P3’s is slightly off D65. But there is a subtle difference between Apple’s Display P3 and DCI-P3. Traditionally, the P3 color space has been used for feature films deliveries. With newer Mac OS’, the default setting is Display P3 color space. So Apple created a default color space profile called Display P3 to make use of their wider gamut monitors like iMacs and MacBooks. While older computer monitors still use sRGB, Apple’s newer monitors can encompass P3 color space which means more gamut or colors can be displayed. In the past, Mac displays were limited to a fairly standard smaller sRGB color space. On Light Illusion’s website, they have a great chart illustrating how ICC profiles work: These are found in System Preferences->Displays->Color tab. Display profiles define how the Mac drives color values to the monitor. To read more about levels, check out my other article about that here: Color Management for Macs and Resolve Display P3 and Mac Display ProfilesĮach Mac OS ships with it’s own ICC display profiles. It’s far more common to have color shift issues than levels issues. Options for mitigating these color shifts to ensure that at the very least you can understand and control how your color is displayed across various displays.Īs a caveat, these color shifts are different than the levels issue that so many people get hung up on. Why colors shift between DaVinci Resolve’s viewer, QuickTime and YouTube.Ģ. I hope if nothing else this will help people understand what’s going on.īy the end of this article you should understand:ġ. By using old school color bars and real world images, I’ve created real world tests to describe what is actually happening under the hood with our color. Many users aren’t aware of how ICC display profiles, QuickTime tagging, and internet browsers are interpreting their colors from Resolve. Mixing Light has a ton of great tutorials on calibration: Instead, my goal is to provide workable options for dealing with Apple color management and Resolve. There are other resources on the internet to do that. My goal with this article isn’t to describe how to professional calibrate an external monitor. So how do we ensure that we maintain the color accuracy from our grading monitor on Mac computers? Is there more than we can do besides just relying on our calibrated monitor? Under the Hood of Apple’s Color Management From Resolve to QuickTime to YouTube, the color in your video could shift quite a bit. So even if you use a professionally calibrated monitor, there are issues with translating that color to a computer display. Not only that, but more and more content is being delivered to the internet only. While this is the preferred method of working, a lot of newer users don’t have access to expensive displays or calibration. Since external displays can be calibrated much more accurately, you can trust your external display much more than your computer display. In this way, any OS color management and computer display issues are avoided. They use a dedicated video hardware and professionally calibrated external displays. Professional users deal with these color shift issues by bypassing any OS color management entirely. But that opening also exposed a gap in knowledge and best practices that professionals accumulated over years and years of testing and failure. This has been great for the industry as a whole. When Blackmagic Design bought DaVinci Resolve and lowered the price to $299, they opened up this professional tool to the masses. From the old QuickTime gamma issue to newer P3 displays, there has always been a struggle. This issue has plagued users of DaVinci Resolve, Mac OS, and almost every piece of post production software for years and years. Relative path mac terminal.Ah, the dreaded color shift between Resolve and QuickTime.
