Question

Now in Beta: Enable Log Color Management with a Single Click

Premiere Pro disables automatic log color management for Sony XAVC Slog clips as a default in this latest beta. It now has a new preference setting for easy enabling of the feature.

 

This is a change from the previous behavior where automatic log space detection and color management for Sony XAVC Slog video was enabled as a default, and imported XAVC clips were color managed.

 

For Premiere users that did not want their XAVC Slog clips color managed, they had to manually override color management and set each clip to Rec 709.

 

In this beta, the behavior has changed -- automatic detection and color management of  XAVC Slog clips will not be the default behavior. Premiere users will have to “opt in” to use it.

 

Premiere Pro users can decide if they want automatic detection of Sony XAVC Slog clips, and color management by enabling the new “Log Color Management” setting in the preferences panel, by going to File > Preferences > General and checking “Log Color Management”

 

 

FOR LEGACY PROJECTS WITH XAVC CLIPS INTERPRETED AS SLOG

 

If you have legacy projects with XAVC SLog color managed clips, and you want to keep working with this workflow, you’ll have to enable the Log Color Management preference after you open your project. Clips that were automatically detected and interpreted into log color space will only be color managed if Log Color Management is enabled.

 

ADOBE MEDIA ENCODER

 

The Log Color Management preference is also in AME so Premiere users can enable and disable automatic Sony XAVC Slog detection and color management on export.

 

 

COLOR MANAGEMENT GOING FORWARD

 

Sony XAVC Slog is currently supported for automatic detection and color management with this new feature, support for Panasonic and Canon Log formats are coming soon.

 

Automatic detection and color management for log video formats is one part of a larger color management and tone mapping system in development for Premiere Pro that will be introduced and validated through the beta program.

 

Automatic detection and color management will always be opt-in for Premiere users, the Rec 709 and LUT-based color workflow will remain as the default.

Jake, if you're on Mac and adding a gamma LUT on export to make the media look 'correct' outside of Premiere on that Mac ... that's because of the Mac ColorSync color management utility.

 

A LONG proven, established issue, recognized by all the top colorists and color management experts. And it's because Apple doesn't display Rec.709 media correctly. They use a 1.96 gamma for display, which has never been part of any standard for display of Rec.709 video media.

 

That's the camera encoding gamma, not the required Rec.709 display gamma, which is 2.4.

 

So "Adobe" can't fix what Apple busted. Period.

 

And I work for/with/teach pro colorists. Who are mostly Mac based, and pissed as Hades at Apple over this.

 

Now ... understand! ... when you apply that LUT, you may make it look like you expect within the Macosphere. Outside, you have introduced a HUGE problem.

 

For any Rec.709 compliant system, that media will now be WAY too dark ... crushed blacks, oversaturated.

 

And of course, your Mac is also lifting the shadows of every professionally produced media you watch on that Mac via Quicktime, Safari, or Chrome.

 

I wonder ... have you noted it's doing that, which it is?

 

Probably not, because you think that is 'normal' for that media ...

You've been replying that same excuse for years. Everyone gets the difference between the 2.4 and 1.96 gamma and quicktimes problems. The display colour management option doesnt work correctly, ive used windows systems, and calibrated displays with an i/o box, and the display colour management doesnt match the results on a mac, it crushes the shadows. And even if it may not be technically correct, it would be good to give users the option. Resolve has an option to 'Use mac display colour profile' and FCP displays it this way using colorsync, so it would be nice to have a CHOICE if we want to work this way.  And I have edited videos using FCPX and the colours looked fine after on my LG Oled TV, but premiere never seems to match. I have an external monitor and a computer for when i want to get colours right.

I agree with @Shebbe — this is just a temporary "band-aid". By trying over simplify color management without proper color science, you eventually end up forcing your professional customers to use other tools for color critical work. I understand the goal of trying to simplify color management, but the direction that lead to this "Log Color Management" enable/disable option, unfortunatley seems like a result of making fundamental changes to the image processing and color pipeline, without fully understanding the complexity and needs of your professional customers.

 

I know you are working hard on improving color management and I appreciate that you publicly share new features and ideas with your Beta community like this. However, I do not think any of your professional customers feel confident about the direction you are heading in, based on features and ideas shared in a context like this.

 

I would highly recommend that you try to communicate a clear direction for where you are heading in terms of color management. In fact, at this point I think you owe it to your professional community. There is already a statement that was made back in 2021, regarding OpenColorIO and ACES from Adobe, shared via the ASWF community: https://www.aswf.io/blog/industry-support-for-ocio-v2/

 

Adobe
Adobe is currently working to implement an ACES workflow inside an OpenColor IO v2 wrapper for its tools most often used in production pipelines: Photoshop, After Effects and Premiere Pro. Lars Borg, a SMPTE Fellow and one of the developers of ACES, is a core leader in Adobe’s color team who is leading the charge. His colleague Patrick Palmer, Principal Product Manager for Professional Video, notes that the ability to support ACES in OCIO v2 without a 3D LUT is a significant step forward to driving broad-scale support for ACES, and that the improved GPU renderer in OCIO v2 is a critical area that will drive adoption.

Palmer also shared the following about Adobe’s roadmap: “We are looking forward to having one means of setting up a consistent viewing environment for high dynamic range (HDR) footage. Adobe tools are found in nearly every production pipeline. While our tools have supported almost any colour working space, creating a viewing environment consistent from the set through to post-production, which often spans multiple vendors, was complex and required a high degree of management. We feel that by supporting OCIO, our users will work with higher confidence about what they are viewing. OCIO is becoming standard and allows us to have the same framework as other applications – which yields the same results in all participating products.”

 

If this really is your goal, why not share that here in the Community forum as well? ACES via OCIO is already in beta for After Effects. Clearly, you would need to also support ACES via OCIO in Premiere Pro, in order to handle color management with Dynamic Link and After Effects.

 

To those of you in this user community, who still don't understand or appreciate the complexity of the whole situation. Here is an attempt at showing an example of why many professional customers are confused and frustrated.

 

Transforming Wide Gamut High Dynamic Range images to SDR BT.709, without proper color science, tone mapping, gamut mapping and gamut compression, leads to critical issues like the example in the attached image, with clipping colors and horrible looking images.

 

 

If you think this is just an "edge case", think again. Lots of very smart people spent months, if not years, on this particular problem within the Open Source ACES Working Group community. As we speak, they are working actively on ACES 2.0 with new and improved Output Device Transforms: https://community.acescentral.com/t/aces-2-0-cam-drt-development/4700


For those of you unfamilar with the fundamental understanding of color gamuts, gamut mapping and gamut compression, have a look at this introduction to the topic: https://github.com/jedypod/gamut-compress/blob/master/README.md

 
At the bottom of this page, there is actually a link to most of the test files used in this ACES Gamut Compression working group, where the Sony FX9 Elvis clip I used in the example above originates from.

If some of you still wonder why the use of "Log Color Management" in Premiere Pro in its current state is an issue, have a look at the difference in the attached image below. This is one of many reasons why real professional workflows don't rely on Premiere Pro for color grading and finishing. It is also one of multiple reasons why many who are forced to use Premiere Pro for color critical work still rely on LUT based workflows, using professional LUTs created by color scientists and camera vendors as their Output Device Transform (ODT), and do any color adjustments before/under the LUT (ODT).

This is good on two levels - having the option to turn it off is great and the fact that the actual colour management works now (compared to say v22.5 which was the last I looked at it when it was blowing out highlights on Sony log footage - screenshot is same clip, same settings in Pr).

I gave quite a lot of feedback back when the Tone Map feature was introduced for plenty of valid reasons. Now we see another feature where I have the feeling that it is yet another "band-aid" on top of previous design decisions when the initial approach is just not as refined as it should be.

 

What immediately strikes me first is the naming. Why 'log' color management. And referring back to my initial feedback in the link above, why not fix it properly and give us the option to fully disable color management. As it stands now from what I can tell, only .jpg and .png files with embedded profiles are auto converted to Rec.709 but no others. And sometimes we don't even want this. The checkbox should just be named [Disable Color Management] and turn of all auto conversions regardles of which file it is.

 

On top of that we still need a proper way to actually manage it instead of hoping that some random camera log space gets added to that log list. Having OCIO in AE is already a great step forward which will reach Premiere Pro as well soon, but I believe that next to that a solid foundation for Adobe color management can also live. However making checkboxes here and there to 'fix' stuff isn't going to cut it. What's even the point of having it bound to a select few filetypes. Not all Sony camera's bring over the metadata, what if you'd want to use management but you get to only select Rec.709.

 

I cover this in my other feedback as well I think but I really hope someone at Adobe will consider a much more efficient and open approach to handling this. It can be a complex topic, especially for beginners. But not giving us the tools and freedom to control it makes things only worse as it will sometimes will work and sometimes it wont.

Amen!!!!!

 

I will simply add that my feature request for a single full-on ECM ... essential color managment ... panel, was moved from a request to in process. Which means only that they are testing out the idea, and we may or may not at some point see it in beta.

 

But ... that is what we would need to be able to properly handle the many options we truly need now that Premiere is no longer Rec.709-centric.

Hey @eric escobar this is great timing as I'm about to start my first Sony XAVC project. I actually like the look of the footage when "Log Management" is enabled vs. the LUT that I was given. Premiere's de-logging, as Neil called it matches what I saw on set more closerly than the LUTs I have and will be a better starting point for grading.

 

I'm currently unable to test much in the way of Lumetri in Premiere Beta because the app crashes every time I add the effect ( I already filed this as DVAME-4200208. I couldn't classify this as Premiere, which is why it's labeled 'AME'), but since this is an app preference, what will happen to my graded clips if this project is opened on another machine that has "Log Management" disabled? If I'm grading based on the look of my footage with this option enabled, does that mean my grade could look drastically different somewhere else?

 

Thanks!

Yes. Opening on another machine with log color management disabled, will return your clips to their original gray “loggy” appearance. So any work you did to them in Lumetri will just be done on top of that image.

This is the very first phase of a LUT-free color management workflow that will exist alongside the current non-managed workflow of camera LUTs.

We want to offer Premiere Pro users the option of choosing one or the other, based on the particulars of their workflow needs.

As this new workflow becomes more feature rich and useful, I hope its use becomes more wide spread.

That said, you ask a salient question, how do we let users know that any particular project is log enabled or not. Especially in environments where both color workflows are used.

I will take this question to the design and engineering team.

Thank you for jumping in and taking this for a spin. There’s more coming and this feedback is absolutely vital in the development of the tool set.

Great, thanks for all that info! I work exclusively in the beta and will be working on this project over the next few months. I'll leave Log Management enabled and hopefully will be able to incorporate new features as they're released. Hopefully that crash with Lumetri will be easily reproducible and fixed soon as I'd like to keep this entire project in the beta.

But this is only for Sony XAVC clips, right?

 

So BRAW and others aren't included ... ?

Hello Neil, 

That's correct, this is just for Automatic Detection of Sony XAVC Slog clips.

Thanks Eric, this is so welcome!

 

A lot of users do want their log "untrammeled" by anyone else's choices, as their workflow is already set to efficiently de-logify their media.

 

And one could work the other way ... take the 'base' de-logging that Pr does, and create a user-designed normalization for that media as a replacement. I've done that for a few log formats, and it works as well as having a de-logging preset or LUT. Just a different process.

 

But if you already have a known and working pattern, why make a new one, right?
