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.

Modifiable Media File Properties
The following properties are stored directly in a media file but, unlike other media file
properties, they can be modified via the clip. When you change one of these properties
in a clip, the clip’s media file is modified.
 Reel
 Media Start
 Media End
 Aux 1–2 Reel
 Aux TC 1–2

Because these properties are stored directly in your media files, you don’t risk losing
vital logging and capturing information if you delete clips in your project.
