Some NLEs waltz in 3/4 time. Others rock in 4/4. FCPX is free jazz.
Organize as simply as you want or with a complexity and depth of multi-catagorizing sources as you see fit with Keywords, Smart Collections, Favorites, multiple in/out points per clip.
Rather than being limited to rigidly constructed relationships, connected clips, secondary story lines, auditions, allow situational flexibility at any point in time.
Roles allow you to organize the clip’s intent without the constraints of visually linear arrangement.
While non everyone appreciates free jazz, I think it’s important to have an NLE that offers the professional the creative freedom away from the constraints of traditional time signatures and harmonic structure.
