Media File Properties
Some clip properties are derived from the media file itself. Master clips refer to these
properties directly from the media file. Final Cut Pro caches some of the media file
information in clips in case the media file is disconnected. Affiliate clips refer to these
properties via the master clip, so they are also considered to be shared properties. Most
media file properties can only be modified in the media file, or by recapturing with
different capture settings.
