Ultimate Letterbox Pack exclusively for Final Cut Pro.
Save time, effort and processing power with this extensive preset pack.
21 adjustable, cinema-grade letterbox / film matte templates housed inside FCPX as a plugin (not a PNG layer that needs to be dragged in like most letterbox templates - adding a PNG layer above your project affects processing power and slows down your edit).
