Question

Grey thumbnails in Media Browser: Color Management enabled

Hi!
I may have just discovered a possible problem in the Media Browser of Premiere Pro.


When turning Color management on ("Display Color Management (requires GPU acceleration)", found in Edit -> Preferences -> General..., see attached "Preferences.jpg"), the thumbnails for JPEG files shown in the Media Browser are all grey (see attached "Media-browser-CM-ON.jpg". When turning Color management off, the thumbnails show as normal (see attached "Media-browser-CM-OFF.jpg").

 

I have noticed that thumbnails for videos and Photoshop files (PSD) seems to show as normal even with Color management turned on. Also, PNG files show as normal thumbnails.

 

The contents of JPEG files show OK in the timeline, in the Program window and in the Source window even when Color management is on.

 

Otherwise, turning Color management on seems to work OK. On my wide gamut color managed monitor (Eizo CG2730) the colors shown on the timeline, in the Program window and in the Source window are all correct (matching the same JPEG images as shown in Photoshop). Of course, when turning Color management off, this is no longer true on a wide gamut monitor like Eizo CG2730 (colors are no longer correct, but that is to be expected).

    I suddenly had this issue, too - and it turned out that it was due to DropBox files being 0 bytes (but still there, so not missing). I must've made some files Online Only in the heat of the moment, and accidentally made one of the embedded files 0 bytes. After making all files Available Offline it started working again.

      yup, this is a gotcha for many types of files and sometimes dropbox spontaneously changes the status of the files...  fwiw, it's a good idea to check this status for regularly used files on a regular basis.  I have a folder which contains all my premiere projects stored locally which automatically mirrors on dropbox which gives me confidence in always having my projects saved...  Since I pay a monthly fee to dropbox, I also can access different versions for a month...

       

      fwiw, dropbox support is problematic and they'll try and avoid due diligence.  Had a file uploaded for review with a link that didn't work.  Went to support and they said they appreciated my post and suggest I jump thru many hoops to troubleshoot...  I asked repeatedly if they had tried the link?  No answer.  I asked again...  No answer.  Finally went ballistic and they admitted it was their problem and fixed it...  Not the worst example of corporate support I've experienced, but still sucked.

        If you are working in Rec.709/SDR, the monitor should really be set to Rec.709/SDR settings also. When you turn on the DCM option, it looks at the monitor ICC profile, and tries to remap the image to display a correct Rec.709 image within the monitor's space.

         

        So I think this might be part of the problem.

        Hi!

        Thanks for the feedback!

        The problem shows up in the Media Browser browser, before I start working on any import or sequence. I just included Rec.709 as a color space when preparing the images in Photoshop as an additional test. It does not seem to matter which color space is used for the JPEGs browsed. When Display Color Management is turned on it seems that JPEGs with any color space/profile turns up as grey squares. So far I have tried sRGB, Adobe RGB and Rec.709 (in my normal workflow all my JPEGs have an sRGB color space with an attached sRGB ICC/ICM color profile).

        Again, what is your monitor set to for ICC profile and for color range et al? Rec.709, I hope?

        What is the color space of the jpgs? Should be sRGB.

        Hello,

        I have tested with JPEGs having sRGB, Adobe RGB and Rec.709 color spaces. None of the JPEGs show (just grey squares).

        The same image as a Photoshop PSD file saved having sRGB, Adobe RGB and Rec.709 color spaces all shows normal thumbnails.
