Editing : Fades and Crossfades : Separating Clips that Include Fades or Crossfades

Separating Clips that Include Fades or Crossfades
You can create clips from track material that overlaps with fades or crossfades. If the Preserve Fades when Editing option is enabled in the Editing Preferences page, the fades from the source clip are adjusted to the new clip.
To separate a clip that overlaps with a fade or crossfade:
1 With the Selector tool, drag to select the material for the new clip.
2 Choose Edit > Separate Clip > At Selection.
Where your selection overlaps any fade-ins or fade-outs, the fade is trimmed to fit the selection.
 
 
Where your selection overlaps a crossfade, the crossfade is separated into a fade-out and fade-in at the selection boundary.

If the Preserve Fades when Editing option is not enabled in the Editing preferences, any fades within the selection are deleted when editing.
