Colorist's teach that in the use of any LUT, you need to "stress test" it first, to find where it will break your media. LUTs are very useful, and very dangerous. All done from a simple table of input:output data. They're a very simple matrix operation: this value on input goes here for output. LUTs are called "the dumbest math out there" by colorists for a reason. So, that LUT is not something I'd recommend using especially in the Basic tab's Input LUT slot. Now, just adding that LUT, and see how it both clips a TON of highlights to white while crushing a lot of shadow tones to black, and blows the Vectorscope (showing saturation) way out from what it was. But that LUT is really pushing the contrast/saturation hard. And of course, that could make quite a difference. I don't know what he's got his CM and monitor set for. All screens are different, and you as creator have no control over them whatever. That's one of the frustrating things of working video post. No one outside the colorist's suite ever actually does, of course. you didn't see what the colorist was seeing. But I'll bet you didn't realize that your Mac is showing you all pro produced media lighter in the shadows than the colorist graded it, did you? Because of course. That will still be a correct image shown on a fully tricked out pro-calibrated Rec.709 reference monitor. There isn't any way to get both a correct image inside Premiere and in QuickTime on a Mac. and are ticked royally at Apple for so screwing with standards. VLC and Firefox apparently do not allow ColorSync to handle their CM, and so tend to give a more correct image on a Mac I'm told.Īnd I work with a lot of noted colorists, I even teach pro colorists. ![]() If that wasn't on before, it may well make a difference in how the video now appears in the Premiere monitors. make sure your Preferences is set to "Display Color Management" as checked/active. With that selected, Premiere looks at the ICC profile for a monitor, and remaps the image within Premiere to show a correct, Rec.709 standards, image. Which most users don't, whether on a Mac or PC. Unless you do check that, Premiere assumes that you have a totally accurate, calibrated and profiled pro-level Rec.709 monitor setup active. when working in video in Premiere on a Mac, you should make sure the "Display color management" option in the Preferences dialog is checked. and the other apps/browsers that allow ColorSync to manage the image. And because of the mis-application of standards by the Mac CM utility ColorSync, it is actually QuickTime. That same file, shown on a properly setup Rec.709 system, will look very close to the image in Premiere, and not like the image in QuckTime. ![]() But outside Premiere on that same Mac, in most apps and browsers, the image will be lighter in the shadows and a bit less saturated than within Premiere. With the DCM option checked on a Mac, a proper Rec.709 image will be shown inside Premiere. between the two mis-application problems of the Mac ColorSync utility, what does that do to an image? In two ways: first, they apply only the first of two required transforms to the image data, and second, they apply an odd 1.96 gamma instead of the required 2.4 gamma. ![]() because Apple chose to apply a very unique 'take' on Rec.709 video standards. Working color in SDR or Rec.709 video on a Mac is a challenge. I sent the same footage to a buddy and asked him to create a LUT for me to test if it was the footage or premiere. However, another interesting point is when LUTs are utilized. However, as expected, this issue is further exacerbated when applying a color grade. The above is a screenshot from the Premiere program window with no effects applied.īelow is a screenshot from QuickTime Player.Īs you can see, Premiere Pro is grotesquely distorting the video. To demonstrate what is happening, I will share some screenshots: So I then uninstalled Premiere Pro entirely and reinstalled it to try and remedy the problem. When I first noticed the issue, I tried quitting to fix the problem however that did not work. Premiere Pro 2022 (22.1.2) Apple Silicon version Roughly 13 hours ago, I opened Premiere and realized that displayed colors were off. Hi, I am currently running Premiere Pro 2022, and I am experiencing some strange phenomena.
