Title says it all really!
This is a Final Cut Pro X Library template I use constantly for my edits on short, commercial and feature work.
Feel free to download it here
It includes already labelled and pre-established events, smart and keyword collections, as well as a dedicated event to housing a Roles setup. Compound clips which just have small, bite sized generators and audio clips inside them with roles assigned so when the Library opens, they launch into FCPX.
Feel free to use this template as much as you want! Let me know what you use for your own projects, always keen on seeing how other people organise their work!
