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.
Ah, the dreaded color shift between Resolve and QuickTime.
