Cannot generate thumbnails error message

Mark3
Just downloaded trial version: the selected image does not render and display properly - remains very coarse. I use an Eizo CG243W.

Also, how do I activate dual display functionality?

Never used Capture One before so appreciate any answers

    Could be an issue with the selected image (unsupported file type?) or the monitor profile. Try another file type or another monitor profile.

    Dual display: Window menu -> Viewer or Workspace. (Pro/DB only)

    Same problem, no answer from Phase One. I've completely uninstalled the software, downloaded a new version and reinstalled v5 a half dozen times now.

    Reinstalling software is apparently not the solution, it seldom is. Removing the preference file might be a good starting point in troubleshooting.

    Hi,

    I had the same issue with C1 v5. The support guessed, that it's maybe a v4 ICC profile of the display I use (CE240W, calibrated using Eizo ColorNavigator). I tried that, and generated a new v2 profile with a different software (ColorNavigator has no settings to force it to make v2 profiles), without luck.

    Purging the preferences et. al also did not help.

    Last night I went through all settings again and stumbled upon the proofing settings (View -> Proofing Profile). It was set to "No Profile". After changing that to "Selected Recipe" (i.e. TIF, ..., ProPhoto RGB), C1 settled and the previews rendered sharp. Also no more error messages in the popup.

    So it was neither the display profile, nor broken preferences. For me it was the wrong proofing profile.

    I'm unsure why "No Profile" is selectable although it seems unusable. Maybe I misunderstood something…

    Marcus,
    Thanks for the feedback. The setting Selected Recipe is indeed the preferred setting and was the default in CO4. Apparently this changed in CO5, which is not a good idea as most users are not aware of the setting.

    Thanks Paul. The problem is I keep getting error messages that says Cannot generate thumbnail image. This means that I am looking at a low res fuzzy image with no corrections. Clicking on sliders moves the histogram, but doesn't seem to affect the image. Uninstalling means I removed the following files and then downloading a fresh .dmg from the Web site:
    anything .cop
    com.phaseone.captureone.LSSharedFileList.plist 

    com.phaseone.captureone.plist 

    Capture One.col45 and .col50,

    /Library/Application Support/Capture One
    
Applications/Capture One.app

    Any recommendations?

    Full text of the error message:
    Description: Cannot generate thumbnail from proxy file: too few color profiles

    BillGreen,
    Have you already tried Marcus321's recommendation? View menu, Proof Profile, Selected Recipe (CO5 Pro/DB).
    Phase One has already acknowledged being a bug in CO5 in that by default no output profile is selected. Capture One needs an output profile to be able to generate and display thumbnails.

    Thanks Paul, that fixed it. I didn't realize that was the same issue. Now since I threw out ALL my C1 files as I was instructed on another thread, I have a few thousand raws to reprocess.

    Meanwhile (having posted original query) I found by trial & error that going to View -> Proof Profile -> RGB Output, then choosing my monitor profile (done in the past and only appearing under RGB Output), everything displayed properly.

    However, reading the Manual, under "What color space is the image viewed in?" it says "Default is set to show the image in the viewer in the color space selected in the highlighted
    process recipe." I'm now trying final edits in Lightroom 2 so can process for opening in LR2, where Adobe RGB would seem most appropriate of available options. Images still view fine with Adobe RGB selected.

    A few points to the posts above:

    - Color Navigator creates V2 profiles on Mac

    - The naming convention in Color Navigator running on Snow Leopard causes problems for Capture One to read the monitor profile.
    Change the default naming convention in Color Navigator: leave out blank space, comma, dash, bracket and period.
    So change "CE240W(123456) 120cd, 0,3cd, 5500K, 2,2.icc" to e.g. "CE240W_123456_120_03_5500K_22.icc"

    Thanks Thowi, I assumed the first point, but was not yet aware of the second (still testing Snow Leo till all apps are compatible).

    Various posts much appreciated. Forgive ignorance, but exactly where can I find/change the Color Navigator profile in the way suggested?

    Open Color Sync -> devices -> monitors -> open the active monitor profile -> go to "local profile description" (or however it is called in English).
    Change the ASCII- and the Macintosh name.

    When you're calibrating the monitor set the appropriate name in Color Navigator right from the start.

    OK: did the profile renaming in Color Sync: opened Capture One: another 'failed to generate thumbnails' message, then re-selected the monitor profile (the previous name had not updated - Color Sync confirms new names in Mac system): normal image rendering again.

    I'm not sure renaming profile makes a lot of difference at this stage. Just have to be sure to select appropriate profile first time using Capture One, it seems to me.

    Another factor new sessions no longer default to all recipes selected (yay!) so even if the proof profile is set to selected recipe the thumbnail generation "events" still happen if you haven't selected a recipe. By default it seems nothing is selected, which is good please don't change this, please find another way to fix this behavior. v5 is looking pretty good but we're still beta testers.

    no, not good. Except if you embed the camera profile (so input profile = output profile). With any other color space set as output space the histograms display nonsese. Too, the RGB values do not show up (even not for the camera profile).
    So that's a bad workaround. Default must be "selected recipe".
    As to the recipes in V4 that sucks. But that's another story.

    I was referring simply to the convenience of not having to go and unselect all the processing recipes I don't want in a new session. I'm sure there's other ways to achieve the desired result. I don't think I'm actually disagreeing with you, but I'll admit to possibly not understanding you. 😊

    I may not have been clear, my point is without selecting a recipe the default "selected recipe" still produces the errors. For me that wasn't obvious until I started digging.

    The latest pearl I received from tech support is it's a permission problem on my machine. Tech email farm still as helpful as ever.

    Just had the same issue on SnowLeopard and Capture One 5... ☹️((

    We have no problems using Color Navigator 5.2.3 with Leopard and Capture One 5 - and all sorts of profile names.
    Now after having installed the latest version of Color Navigator on our new MiniMacs - the only way for using it with Snow Leopard - and properly profiling the CG243 no preview could be generated anymore in Capture One 5. When changing to a default profile, the previews were ok again - and the target profile was selected already.

    I will try creating a new profile name in the save dialog in ColorNavigator - hope it helps... More about that tomorrow then.

    Problem solved:
    You have to create a new target in ColorNavigator 5.2.5 and name it in a very simple way (without spaces) - not trying to rename the profile afterwards... and the problem is gone.

    Thanks for the hint. I guess that this is a problem created by SnowLeo since I was using these "strange" profile names with dashes with Leopard and Capture One 5 before without problems.

    I have solved,
    move the profiles from "user/home/library/colorsynch/profiles" to "root/library/colorsynch/profiles"
