john294
can anyone tell me why this error window is appearing.

thumbnail generation failed

and how to fix it.

I've dumped all the phase.com files from the prefs and restarted.

Thanks

    This can happen when the raw file is corrupted. A single corrupt raw file can generate multiple instances of this error because CO4 retries generation when opening a folder.
    Look in the Cache subfolder and find the missing preview file (based on file number should be easy). Remove the corresponding image file and open CO4 again.

    All the preview files are there and all correspond correctly to the Raw files.
    Any other ideas, still having problems.

    Look at the size of preview files for any irregularities. If yes, you found the culprit.

    The files are all around the same size. 1.7 - 2mb each.

    I'm so frustrated by this today that I've given up and started a new session. It's still doing the same thing.

    The error message regarding the thumbnails says there are too few color profiles. It reads Cannot generate thumbnail from proxy file too few color profiles.

    It could be your monitor profile. Change your monitor profile or re-calibrate and try again.

    OK. I dumped all the prefs again and started up a new session and it seems to be OK. We did calibrate the monitor after we set up the session which may have caused the issue.

    Is there a way to bring all the files we have shot so far into the new session without corrupting the new session. I need everything in one place. I now have nine shots in the previous session.

    There was a period during v.4.5 or 4.6 when everything was going just fine, all the clitches seemed to have been ironed out. Since installing Snow Leopard and going to 4.7 and 4.8 it's been crashing multiple times and seems a lot more unstable.

    Thanks for your help, John

    John,
    Moving images around I would normally suggest to do it within CO4. However, due to the errors, it is best to close CO4, open Finder (or other browser if you like) and move the images from one session folder into the other without the Capture One subfolder to prevent the previews come with you.

    Working with Snow Leopard now is still quite early days. In general, applications and hardware support (monitor calibration) have issues to iron out as well does Apple. Regarding CO4 install the latest (4.8.3 currently) version and update as soon as it becomes available because I expect more issues will surface. Phase One is on it, no doubt.
    I am currently running Snow Leopard on a separate disk volume and noticed lots of issues both software and hardware suppliers have to deal with. Will take another 2 months at least. This is normal for a new operating system introduction.

    Thanks for all your help Paul. I think it's all to do with the monitor calibration. If I drag the window off the monitor and onto the laptop screen it seems to be OK. I normally have the viewer window on the Laptop and the main window on the calibrated monitor. I've re calibrated the monitor again and it all seems to be OK. Hard to deal with these problems in the middle of shooting with clients around but managed to sort it out last night.
    John.

    I'm having the same troubles and I've noticed that I get the error when I open the session on a different monitor. Also if I restart the system the Eyeone software that checks the monitor profile on startup thinks that the monitor profile is not valid.
