Thanks Joe, Noah and Jeff !
I really appreciate your help on this, this is a really cool community.
So I was trying some of the things you guys mentioned, so far I noticed a big change when switching to proxy files, so I am going to start doing that from now on.
I am editing from an USB 3 Drive, do you think I could get better performance from another drive? Like thunderbolt, or something else? Any suggestions?
I am gonna start editing a new project with about 2000 files, so I can try to replicate what happened before and see if working with proxies at that scale solves the problem I had. I will post if I find out anything interesting.
Thanks all again!
