The project server (
download link) can be used to install a safe multi-user
network based project library (based off PostgreSQL) to support simultaneous collaboration. It will be available on your LAN subnet, will not need internet access unless you need to login to internet services or to validate licensing. But it is not file or folder based.
DaVinci Resolve by default starts you off with a single-user disk-based
local project library and you can create more. Accessing the project files with more than 1 software simultaneously - even with Dropbox etc for syncing - puts it in risk of corruption. We discourage network folders - even ignoring the network latency and implications on Live save, the ability to simultaneously access (and write and overwrite) a project file risks file corruption.
The third way to access is the
Blackmagic Cloud project library - which offers both portability (allowing you to work from your home or head to a coffee shop) and remote multi-user collaboration (like a network project library).
