Question

Which color profile to use for assets when NOT using color management.

Hello,  my computer monitor is calibrated at rec709 gamma 2.4

I'm not using color management because it isn't needed as per Neil's advice https://mixinglight.com/color-grading-tutorials/demystifying-premiere-pros-color-management-and-finishing-pipeline/

 

Now that I'm not using CM, what I can't figure out is, which color profile to assign the imported assets (tiff images) should I....

 

A) create the tiff in photoshop, embed the sRGB profile in the tiff and then import the asset into AE and leave it alone...

OR

B) same thing, but when it's in AE, interpret the asset's profile to rec.709 ?

 

final project for bluray disc / hdtv. 

 

I'm leaning on A...  


Thanks!
Letty

I just watched part 1 of your Insight, Neil, nice!

 

I'm with you here, use CM in AE and set up your profile in PS and import it into AE. In the top of the Project panel you should see the profile associated with the TIFF sequence. Does it show what you expect?

 

"Linearize Working Space" will change how values handle when you're compositing (although you don't have to just be compositing for this to be useful), but you'll still be outputting your sRGB values: https://www.youtube.com/watch?v=jCVIqG-D2Vk

    OK, so I should turn on CM in AE.  ..and in the project settings work space choose rec.709 in the drop down.

    The big question then is, for the assets, should I interpret them to be rec 709 or leave them alone in their original state of sRGB ?

     

    ...and if I do reinterpret them to rec 709, do I use the regular 709 or the hdtv 16-235 rec709 ?

     

    I was thinking the profile of the assets should match the project settings work space drop down menu..... regular rec 709 2.4 gamma?

    I think I'll just do everything in rec709, all asset profiles and project settings, with CM on.  I don't think I can go wrong with that.

     

    My main remaining issue is to set gpu at 0-255  or 16-235.    I'll just do a bunch more test discs and see what looks better.

    Create the tiff in sRGB in Photoshop.

     

    In Ae, project settings, you need to use the HDTV Rec.709 option. And ... I'd love if say @David Arbor or one of the other Ae wiz's stopped in ... as sometimes it's needed to uncheck "linearize color working space" in Ae and PrPro's sequence setting to "linearize color" ... and other times, not needed or maybe even wanted.

     

    And I never remember those details.

    Hi Neil,

    In your video (part 1) you said to turn off CM if  your monitor is calibrated to rec709...

    Did you mean if your monitor is an 'external monitor' or the computer desktop monitor?

     

    Caz now people are telling me to turn ON CM, so AE and PPro can access the ICC profile created by x-rite.

     

    Thanks,

    Letty

    IF your monitor is able to run full 100% of sRGB after calibration, and you've got say the pro version of the Xrite ( the cheaper version won't fully get it right) you should be ok with a monitor set to sRGB/Rec.709 and calibrated with the Xrite i1 Display PRO software/puck ... if not on a Mac.

     

    After calibration with the i1 Display Pro, I ran the free version of Lightspace profiling software, using Resolve as a patch generator, to get a profile of my calibration. That's a series of graphs showing desired versus achieved display performance. My BenQ PD2720U was looking pretty good on most of the charts, and the all-important deltaE value was well below visual effect, and the only place it was close to noticeable was one spot in deep shadows.

     

    I'm good to go without that preference setting.

     

    If on a Mac however, or if not using the i1 Display Pro software, you should (probably) always set the display color management preference to on.
