Highlight recovery issue with 12.1.4

Benjamin Wilson
Since updating to Capture One Pro (for Sony) 12.1.4 the high dynamic range, highlight recovery tool is causing issues when I export images. The preview on screen looks fine but the exported files show a very blocky appearance in any area altered by highlight recovery with the brightest highlights going completely white. I also notice this effect when adjusting the highlight recovery slider but the preview goes back to the expected appearance when the adjustment change is completed.

    Have you created a Support Case for the Capture One Support Team to be able to help you?

    What happens if you turn off Hardware Acceleration for output in the Preferences?

    I've never had any image quality issues with files from Capture One prior to this and was interested in finding out if anyone else has experienced similar issues.

    I haven't created a support case yet but will if turning off the hardware acceleration doesn't correct the issue.

    Thank's for the suggestion!

    Turning off the Hardware Acceleration resolved it, thanks again for the suggestion!

    Ok.

    Then there are two things to check.

    Firstly you need to get C1 to regenerate the kernel program for the GPU.

    Have a look at this article and follow the instructions for the Windows version (assuming you are using Windows as we are in the Windows section.

    https://support.captureone.com/hc/en-us/articles/360002404937-Troubleshooting-OpenCL

    (Active links seems to have been disabled - presumably because of some fairly high levels of spamming posts recently when suspicious links were inserted.)

    If you make the Activities Window visible immediately after C1 has presented the main screen you should see the process running. There is also a quite informative Log file available.

    If, for some reason, it does not complete the first time, repeat it.

    Turn Hardware acceleration back on once it has completed successfully (should be fine first time but once in a while some stuff seems to be left around in the temporary work files area either by C1 or Windows. )
    If everything works all should be well.

    However you might still want to check whether you have the latest version of the driver for your GPU. So ...

    Secondly that you have the latest driver for your GPU card. If you have but there still remains a problem it may be that stepping back a release or two may help but that comes later.

    The Driver support may be available through your device manufacturer or you may find it better to go to the web site of the driver firmware developer.

    It's difficult to know what to suggest here subject to an indication of your comfort levels dealing with slightly more technical aspects of PC management. With luck checking the driver may not be a necessity.
