I’ve been running into this issue a lot lately with our workflow. For some reason, every time I try and save my project, Premiere runs into an Unknown Error and asks me to Save As the Project.
I’m using a Premiere Productions pipeline. The production is saved on my NAS drive. The drive has plenty of room (Several terabytes). Every machine is having this same problem. Saving the project on the desktop has no issues. We are all on Mac workstations. Most workstations are running 10.15 while a couple are running 10.16.
The only two things that I’ve found that could be causing this is if the projects (or project itself) is utilizing dropbox in some way – which I am not. The other thing is it could be that the drive is full – but again I have plenty of room.
Have not run into it myself but if you haven’t tried this – reset all preferences for Premiere and get rid of DropBox. I try to keep all software off of my editing workstation to prevent interferences with Adobe Suite. If you’re talking about the commercial service “DropBox” I would relegate that to a different machine entirely as it is constantly running in the background. Or maybe turn it off first and see if that makes a difference.
Can’t answer that last question – just don’t know. I’m wondering if the same type of fix could be used that works when I get a can’t render error… to find the offending clip I render out half of the timeline. If no problem, I know the offender is in the other half of the timeline… so I render that. You keep having the segment of timeline with the offender until you’re down to one clip – or effect – and that’s the culprit. No idea if this would apply to your situation but tossing it out for thought. Good luck! Hopefully other more experienced PP users will chime in at this point.
