8/5/2023 0 Comments Handbrake mp4 gamma shift![]() Something in the Premiere Export/Render engine that doesn’t play nicely with my setup. Now that has nothing to do with Quicktime. But I am seeing the exact same behavior with TIFF exports. I am aware of the Quicktime Player as being not up to professional standards. Wouldn’t “Software Only” take the iMac’s GPU out of the equation? It was the same gamma shift result outside of Premiere. Here’s what I did experiment with: I switched my project to all 3 rendering engines that are available to me - OpenGL, Metal and Software only - and I exported a master quicktime with each engine. I do know that a lot of my colleagues in various companies around town use iMacs as their “professional editing systems” - especially with Premiere Pro. If the iMac’s GPU is the problem, that would be impossible to solve (other than getting a different machine). And I thank you in advance for trying to help me with this. I really appreciate your most recent comments. Maybe I can find more about that and pass on which models may be having an issue. A couple people I know running several systems have gotten odd results with that model. I have heard (as of yesterday) there is a possible issue specifically with certain iMac models with certain GPU's. Where we do get down to is the iMac itself. So understand that when many of us outside the Macosphere talk QuickTime we mean the player. ProRes is of course a very good pro editing/intermediary codec, even if Apple as always is a rather jealous kindergartener about "their" stuff. QuickTime player as distributed for PC's is a rather flawed player. QuickTime player as opposed to the QuickTime codec in ProRes are very different things. Clearly, they were not accurate in your case, and I owe you a very direct and full apology. I made a number of assumptions based on some of the comments in your original post compared with a predominant group of comments that we've had here from other with iMacs and QuickTime. for 18 years, and all we've been ever used to transfer high-end footage is PreRes Quicktime Movies. I have been working with all the top post and finishing houses here in L.A. That's not helpful at all.Īnd you dismissing Quicktime as not professional is also very ill informed. So please don't lecture me about professional standards. If the same thing looks drastically different inside Premiere and outside of it - I could be viewing this on a 100 dollar cheap monitor and it's still the same problem we're dealing with. What I and many others are experiencing has nothing to do with calibration. As Apple said this week - "professionals love our iMacs. So naturally, my iMac's display is fully and professionally color calibrated and it's anything but an "amateur" system. My work shows up on the big screen as well as on all networks and the internet. ![]() I am using a 5K Retina iMac for my very high-end professional editing work, as do many of my other highly priced colleagues in town (Los Angeles). I cannot believe that we are still nowhere close to a solution. I need them to see what I see inside Premiere Pro.ĭoes anyone on the Adobe side have any insight into this? This issue has been going on for years on this forum. I have to send tmy cuts out and share them with clients. The problem is - I can't just stay inside Premiere Pro. ![]() Unfortunately every other app in my Mac universe doesn't do the same and is off dramatically. So there must be something in these exports (hidden tags?) that Premiere adds and that it then uses to display the media correctly. When I import the same washed-out exports into Final Cut Pro X, the washed out colors and gamma stay. Here is another interesting thing I found - when I reimport these washed-out exports (stills or quicktime movies, doesn't matter), inside the Premiere Pro world they look perfectly normal. And it doesn't matter what is clicked in the export window - maximum depth, linear color space. If go through the EXPORT function and export a still image - the colors are faded and the gamma is washed out. When I take a screenshot of my media within Premiere Pro - colors and gamma of the resulting PNG are exactly as I see them in Premiere. Whatever I export - and that's the key here - Quicktime movies, TIFF sequences, stills - EVERYTHING has a washed-out gamma shift and desaturated colors. I just did a round of major testing on my iMac running OS 10.12.5 and the latest version of Premiere Pro CC 2017 - and I have to say - nothing I do fixes it or makes any difference. Many people think it' a Quicktime problem, some say it has to do with video card drives, or with checking "render as linear color space" or not. From what I have seen on this forum, people post all kinds of solutions / explanations as to what could cause this problem. I know this is a topic of major frustration for many of us - washed out colors and a very visible gamma shift when exporting out of Premiere Pro. ![]()
