Hi Jeff,
Pardon the long post, and maybe I should direct this at Kevin, but I pick you. We've been scratching our heads over this for a year.
Trying to get a handle on our cache file set-up. Where best to put them, when to generate, etc. We have multiple rooms working with the same media, maybe picking up a project from another editor. Different configurations but all rooms have robust Mac Pros, PPro 2014, multiple fiber connections, internal hard drives, lots of RAM (48g).
I assume that its better to put cache files on a secondary drive if possible; would you agree?
For a very large file it seems to bog PPro down. I.e. you can't play the clip while its particular cache file is generating. We load entire ballgames, movies, hour long interviews, etc. Is this as expected?
A new user on the same project still seems to have to generate cache files; do you know if these files should be associated with the media, the project, or the user? We do not put the cache files next to the original media; that becomes a nightmare in the finder.
I did a test just now and the .ims files were created for everything I dragged in (ProRes, mxf, avi, mp4, aif, wav, psd, png, tif).
The second part of this test was to clean the database using PPro preferences. Before the clean I had 26,000 ims files in my common folder (tiny, yes, but a lot of files) and 7,000 files in my cache files folder on my internal hard drive (1TB SATA). After the clean I appear to still have exactly the same number of files on each. Just to be clear, the media prefs are pointing to the same cache folder. I can delete manually, and try to do that about every two weeks. The problem there being that I'm working on an hour long show with seven cameras, clips, graphics, music, etc. and I don't want to have to re-generate the big files often. My work around has been to delete all cache files, then launch the project when I'm leaving for the night so they re-generate during down time.
Again, pardon the long winded post. Any help will be greatly appreciated.
Thanks,
Dan
