EDIT/UPDATE: After looking into this for the past three hours, this is almost certainly an issue with a wide gamut display and Premiere Pro. It is my understanding that Premiere Pro does not have any color management options and, as such, operates in the sRGB color space. As is a common issue when displaying the sRGB color space on a P3/wide gamut display like my iMac has, colors will be oversaturated. Within Premiere, color grading looks great but the video export is actually undersaturated because we are compensating for that oversaturation (as a result of the sRGB/P3 discrepancy). It seems as though the only fix right now is to color grade on a sRGB monitor or keep yelling at Adobe to enable color management options within Premiere Pro so that Premiere Pro can actually operate in the P3 color space and not completely skew what the export videos will actually look like.

I, too, am now suddenly witnessing these problems. In nearly all of my exports (H.264 and ProRes – the codec doesn’t matter), Quicktime and YouTube have a disgustingly different, less-saturated and more “washed out” look than what is displayed in Premiere and VLC. I am working on an iMac 5K monitor. I’ve read this thread and I’m still confused as of what to do to solve this issue. VLC is identical (if not, pretty darn close) to what my Premiere timeline and export preview shows. As soon as I upload my export to YouTube or view it in Quicktime, however, I get that desaturated washed out look during playback. This washed out look on YouTube and in Quicktime is the same on YouTube on my MacBook, iPhone, and iMac. This leads me to believe that my Premiere timeline and export preview is not true to what the export actually looks like. What trips me up, however, is how VLC looks the same as my Premiere timeline. Is there a setting within Premiere to fix this so my timeline is true to what the export will look like? Using a .LUT to compensate for lost saturation/contrast cannot be the only solution. Thank you in advance!

Thanks for your help, Chris. As it turns out, it seems as though the problems I am experiencing is an OS issue specific to macOS Sierra 10.12.x. After going back and forth with Apple tech support for quite some time, Apple Engineering did get back to me to confirm that they are aware of these graphics problems causing panics/crashes within macOS Sierra. A workaround that I have been using is partitioning my hard drive with an El Capitan partition and booting into El Capitan to conduct my exporting/editing there. Such a workaround has lead to zero crashes or panics. Although not ideal and rather upsetting, the El Capitan workaround does seem to be the only 100% stable option right now when it comes to PP and AME editing and exporting. Let’s hope Apple delivers the OS update soon to fix these issues!

Hi, Chris. Well, that didn’t take very long. Around 5 minutes into the export I experienced yet another kernel panic while I was clicking a link on a webpage. This is after I tried all of your suggestions above. I do have a kernel panic log if that helps to determine the cause of this issue? Otherwise, is there anything else that I can do to attempt to fix this?

Thanks again for your quick response, Chris. You have already proven to be more helpful and faster than Adobe Technical Support and the Adobe Forums.

Of your list of thing to try, I have done all of them except for the ones that do not pertain to Mac (#4 – most updated Mac OS already installed as this is the only way to update drivers, and #14 – there is no BIOS on Mac). I will be in touch soon to let you know how everything goes.

Thanks again for your help, Chris. I realized I did not need to re-install Adobe Premiere Pro or Adobe Media Encoder on the new administrator account. I fixed the permissions as outlined in the article you posted on the new administrator account and created a batch list of exports within AME to test. The first export finished without a problem (this sometimes happens but more often does not). The second export in the batch list, however, got around half-way complete and once again stopped. Toggling the pause/resume button does not make the export start again. It is once again hanging. Any other ideas on what could be causing this and how I can go about fixing it? Thank you!

Thank you very much for the quick response, Chris. I have not yet heard of this suggestion and will try it now.

Just to confirm – I am creating a new administrator account and fixing the permissions (per the URL instructions) on that new account after fresh-installing Premiere and AME on it or should I try fixing the permissions on the administrator account I am currently using first? Thank you very much for your help.
