How do I tell when the previews are done generating?

Darin
In CO3, there were several ways to see the progress of generating the previews.

In CO4, is there a similar status display to show me if it's done generating the previews? I don't see any status like the list of the files it's generating, the little "dot" on the thumbnail that goes away when the preview is generated, etc.

I didn't find anything in the manual.

Thanks,

    You might have your reason to have such indication, which is not available in CO4 as far as I know. I have not yet missed for several reasons. One is that preview generation in CO4 is much faster compared to CO3, and another reason is that in CO3 it is best to wait till generation is finished, while in CO4 I do not feel such necessity. With CO4 I start adjusting and copy adjustments to all images while preview generation is still busy (again, I must be fast to be able doing that).

    Hi Paul,

    Yes, I see your point.

    However I use CO4 to check the integrity of my RAW files to make sure all the files have downloaded properly. On a few rare occasions, I have had RAW files appear to be fine in PhotoMechanic, but when I have CO generate the proxies, I can see that a file may have been corrupted. So the initial thumbnails in CO look fine, but once the proxies are generated, the thumbnails will show any problems with the RAW data.

    Interestingly enough, I just had a hard drive go bad. I copied the RAW files from the hard drive to my internal drive and all the files had the right file size. I then culled them in PhotoMechanic and the files looked fine.

    Then when I loaded them into CO4.6, the proxies would stop generating randomly. BUT I did not know the proxies had not generated. Since I left it over night, i assumed all the proxies were done. All the thumbnails looked fine. But when I clicked on some to adjust, I got the "loading..." message forever and the image never showed up for adjustment. It ended up the RAW files had been corrupted on the transfer from my external drive.

    I only figured this out by loading the files into Lightroom and Lightroom showed me the corruption visually in the previews it generated.

    Anyway, you can see why I might want to know that all the proxies had generated properly.

    In CO3, I would have immediately seen that the proxies stopped generating.

    While not very elegant, from time to time I've checked the Cache\Proxies folder to see if I have an equal number of .cop files as raw files.

    This is the only way I have found to do it as well, and as you say, it's not very elegant.

    I would also like to see an indication of the amount of files in any given directory like in 3.7.

    I too would like to have "progress bar" or a "counter" showing the status of preview generation. On lower powered PCs, it may be wise to let the preview generation complete before moving on to other tasks that require CPU cycles.

    Preview generation is so slow for me, that 4.5 is almost unuseable. I cannot figure out where the bottleneck is. I have looked in task manager and resource monitor and see nothing unusual. This is on a Gateway FX-6800 with I7 cpu at 2.67 GHz. None of the eight CPU cores show much activity. Only 3GB of ram, but half of it is available. I think it must have to do with the Windows file system. I have over 500 directories in my images folder. This was no problem under XP on C1 3.7, but maybe Vista and 4.5 cannot handle it? The only workaround I have found is to flag folders as favorites and then walk away.
