Colour grade not exporting with Premiere Pro

Hi all, I may be doing something rather basic but here goes:

I am trying to export ANY file type from Premiere Pro CC - H264, ProRes, even still Jpeg images all have the same problem - some, not all (I cannot tell which) of the colour grades are not exporting so the Mp4 or .mov or whatever comes out is washed out - but not completely back to Slog.

It doesn't matter what the footage is - I tried reimporting MP4s and ProRes files and re-exporting them, I tried faking the grade but that just made a mess.

Any ideas? Doesn't make any difference if it's with LUTs or without - same issue

Machine is iMac Pro, Graphics card is Radeon Pro Vega 64 16GB, IOS is High Sierra, Adobe CC is up to date (brand new install)

Many thanks

Alex

Yes, thank you, I tried the Native option - same issue.

I have just run the following test, which to me confirms it is a Premier Pro export issue:

Set iMac Monitor display profile to "iMac"

Export file from premiere pro to H264 (or anything, it really doesn't matter)

Open H264 in Quicktime and put it next to the Premiere Pro Programme monitor for comparison.

The two video images are different - the export is washed out.

Leave everything on screen, in place - not even moving windows around - open Display profile settings for iMac and CHANGE them to sRGB IEC61966-2.1

The Exported QT movie is now the same as the Premiere Programme monitor - to clarify, the QT file changes but the Premiere Pro Programme window remains the same. - Flick back and forth between the monitor settings and the QT movie changes but NOT the Premiere Pro image.

When the H264 is uploaded to Vimeo and I look at Vimeo on a different device Vimeo displays the altered exported image - ie, the more washed out version. If I open Vimeo on the iMac and flip between the colour profiles I can see the colour changing on the uploaded video.

Whatever the iMac is showing pre upload doesn't really matter - Premier Pro is NOT exporting the same looking video that you see on the screen within Premiere Pro. Given that you cannot know where the film will be shown it MUST come out as Premiere Pro intended it - so this remains the problem - How do you export what you see in Premiere Pro so it looks EXACTLY the same.

As noted in the other thread, you proved that PrPro is exporting a Rec709 file designed for sRGB at gamma 2.4, and when displayed either on a monitor set for that or in a properly color managed player outside of PrPro it shows correctly.

And when played in a non-color managed player on a monitor set for some other color space, the player does not correctly show the file in Rec709 gamma 2.4.

Exactly the results you list.

If thousands of pro's use this every day without issue to put out broadcast work that has to pass stringent QC or be rejected ... learn how to set your system for how this works. Like everyone else who's managed this.

And accept that you cannot force all other devices and layers to properly work color management as most don't.

What does it look like when re-imported into PrPro?

Neil

So here's a deal. When I remopved the Lumetri preset and just did fast colopr corrector (the obsolete one) and some Brightness/Contrast all manually and it exported fine. Hmmmmm

Display profile is set to 'iMac' but either way I need Premier to export what I am seeing when I've graded my project and sent it to the client.

PrPro will attempt to show Rec709 in the program monitor. If your monitor is set for something else in the OS you might get a mismatch between what PrPro is expecting and what is happening. At that point, trying to get a precise output is nearly impossible.

Which is why having a monitor profiled and calibrated in Rec709 is really needed. Or better yet, a broadcast monitor controlled via external SDI connections. But at least, a monitor with a calibrated Rec709 profile set.

ok, I follow that, thank you. Surely as the iMac Pros are targeted at Pro Video makers one of the profile settings will be the correct one?

I’m still a little confused though - whatever setting my screen is on, the film exported from Premiere looks different to the film IN premiere - whether it’s watched on my monitor or someone else’s. I just want the same thing to be put out from my expensive creative cloud using my expensive iMac

Sorry:

Tried exporting from PrPro and Media Encoder - same issue.

Importing the clip back into PrPro makes it look over saturated on the timeline (weird!)

Viewing it on the iMac but client is using a PC - same issue

What is the monitor color space? Pro video is pretty standard Rec709, which is designed to be sRGB and gamma of 2.4. Some Mac monitors I know are in other color spaces, which might be an issue out of PrPro.

Tried both, also tried exporting from After Effects.

And my other questions?

Incidentally this became a serious problem this evening resulting in a late client delivery. Exporting is a fairly key part of making videos so I will be looking for a solution to this as soon as possible.

To be certain ... how are you exporting, direct from PrPro or Media Encoder ?

If you import the expirted clip into PrPro does the clip look as it should?

What are you viewing it on outside of PrPro?
