There are 3 people on my team that do most of the work w/ our video files. Lately that means 4K footage shot in RAW. They work out of the office at least half of the time, otherwise at home/etc.
We used to just use a hard drive for every project, but that made it tricky when multiple people needed access at once.
We switched to a NAS in the office and only copy stuff over to external drives when needed. But it lags a lot when actively serving stuff to more than 1 person at a time, so the bottleneck mostly persists.
We've also tried creating proxies for everything through Premiere and working from those via Dropbox sync. This seems like the ideal solution in theory. Maybe we're dumb (probably), but in practice this has been buggy and unreliable.
We don't use AVID or any of that kind of fancy library management stuff. Maybe we should.
Seems like a lot of folks on here might wrestle with this kind of thing. I'm curious, how do *you* do it?
