Can previews be saved to a session?

Postby jasonholtphoto » Wed Feb 20, 2019 12:03 pm

Hi,
I'm wondering if previews can be saved to a session?
I shoot tethered into my laptop and then transfer the session to another machine for editing.
If the previews were already rendered and saved to the session it would save time.

Hopefully my question is clear - I look forward to any words of advise.
Thank you.

Is that right? In a session, previews are the .cop files in the folder

[Session folder]>Capture>Capture One>Cache>Proxies subfolder. So if you copy the whole session folder over, the previews are included.

How do you transfer the session?

Are both machines Windows systems?

They are still always re-loaded and recreated, which is especially annoying when using Capture One Sessions over a NAS.

Working memory will be cleared if a session is closed. People would complain if not.

Opening a session means that the previews are reloaded. NAS devices, in my experience, are not especially quick at servicing a loot of small files. They do better with big ones. In general this is true of any external drives. It may or may not be improved with the very latest drives and external device connections but I don't know if the theory and real world results would match up to such claims as I don't have any of the latest devices and I suspect if I did my hardware would not get the best out of them.

Internally, once the preview has hit the working memory C1 may need to deal with a a number of other matters (including adjusting the size of the display to match the current screen if the preview was not saved in a size that matches the "native" resolution currently employed) before the previews are ready to be displayed according to the settings of the current session. Or, more importantly perhaps, according to the settings of C1 as it is currently running no matter how many sessions are open ... at that point discussion of further implications may get a little complicated - too complicated for this response.

What C1 is attempting to do at the point of load to memory is so put as many images, represented by preview files as saves PLUS the application of any currently active local settings - overlays and Proof values being examples if they are in use would be 2 examples - so that activity after the load is complete is as fast and fluid as the system hardware/firmware, its current settings and the user's editing technique and preferences will allow.

Or at least that is my understanding of what is going on based on observations as I work with the system - usually using sessions containing several hundred to several thousand images.
