Very slow showing thumbnails
Using 4.1.2 on Windows Xp pro.
Have loaded up a load of images (about 1000) and let C1 run for some time to generate the previews. When I quit out of C1 and reload the same folder it seems to re-generate all previews even though I haven't changed any settings.
If you page down the thumbnail view all of the previews are generated again. Its making it very slow to use.
I never had problems before - it just seems to have started. Maybe some setting or file is screwed up somewhere?

Shaun: You could start to verify whether the previews are re-generated after reopening a folder by inspecting their file's date-time stamp. Look for the .cop files in the Cache subfolder. I suspect that it is not re-generated but that it takes CO4 a lot of time to reload the files from disk into memory. This could be caused by the amount of images in a folder. You could try to split the 1000 images in multiple folders and see what's happening. Keep us posted if you like.
Joachim: same advise for you as for Shaun. Regarding your earlier post: maybe because you made a comparison with another program which is probably not used by many other users here, response was low.0 -
Hello Paul,
in my case I just have about 500 images in a folder and I have the same problem with a folder which contains about 100 images.
I did tell you about the other program because there I get my thumbnails very fast and this program (RAW Shooter) works without cache. The cache of Capture One is needless in my opinion. I do not like all the cop files in my foldes and I do not see any speed advantage. It is the same if I have the cop files or if I delete them manualy and then select the folder again.
I now moade a test:
I selected a folder with 136 images. There where no cop files. Phase One needed 102s to built the thumbnails.
Now I selected another folder and I did close the program.
I startet the program again and did select the first folder with the 136 images. Now there exists the cop files. Phase One now needed 85s to create the thumbnails.
This was a little bit faster but to slow in my opinion.
If I select the same folder with the old RAW Shooter it needs about 5s to get all the thumbnails of the folder.0 -

I checked the .cop files and it looks like the were not being regenerated, deleted all of them in the directory and restarted C1 to make them again. Will see if that helps.
I don't think it is the number of files that is an issue as the next folder opened had over 1000 files and caused no problems what so ever.
It might have been caused by C1 crashing when trying to paste a settings change to a lot of files.
The saturation out of the camera on Nikon files is way to low for my tastes so the first thing I do is up it to about 20 and add a bit of shadow recovery, I then paste this change to all of the files (often more than 800).
This will pretty much always cause c1 to crash. The settings are applied it just seems to throw a fit when redoing the previews. I wouldn't normally make the same change to so many images but as I said the nikon profiles are undersaturated out of the box.0 -
Shaun/Joachim,
I also noticed CO4 might crash when applying an adjustment to a large number of images. Next, I suspect that not generating but re-loading (and decompressing) the image's previews and thumbnails takes time. Compare Joachim's observation of 102 seconds (generating) and 85 seconds (re-loading). Best practice is to optimize disk access. Maybe CO4.5, due later this month, shows some improvement in this respect.0 -
Some minutes ago I installed version 4.5 and the result is that this version is even slower as version 4.1.
I am waiting several minutes to get my 400 thumbnails of a folder.
Is it realy impossible to get a version which shows the thumbnails in a short time?
I do not like the hundrets of cache files on my harddisk and when I have to wait a long time to start working I am myself what they are used for?
Captur One needs a lot of space on disk (cache files) and needs a lot of time. For a hobby photografer like me this might be ok (it isn't realy) but for a professional photografer it must be all but impossible.0 -
Workaround!
Don't ask me why, but ...
I've just set some RAW source folders as favorites.
First creation of previews is slow (as in V3).
But the thumnails of favorite folders will be stored!
So if you switch to another folder and switch back to the previous folder... the thumbnails pop up very fast!
Works even after restart of C1.
Downside: after restart the library does not open the last opened original raw folder... it opens the favorite folder from the favorite folders pulldown menu.
But as a workaround... as long as you need the folders, set them as favorites and thumbnails will be created very, very fast.0 -
I tested this and it seems so as if it works fine. Thank you. 0 -
It's not a workaround" - it's a feature.
And it only comes into play with already existing libraries.
If you start from zero, create a new Session, import images from cards or other folders into the Session... these folders will be set as favorites inside this session... and so thumnails are fast.
Finally it makes sense!0
