Extending a Marker’s Duration
When you create a marker in Final Cut Pro, it is simply a marker that ‘s associated with a
particular frame; it doesn’t have a duration. If you want, you can extend the duration of
a marker so that it spans multiple frames. Markers with duration can be used to
precisely define subclips in a clip. You can also use them to mark an entire area of a clip
or sequence with notes, such as for color correction or audio mixing.
To extend a marker’s duration to the playhead’s location:
1 Position the playhead ahead (to the right) of the marker.
2 Do one of the following:
 Choose Mark > Markers > Extend.
 Press Option-` (the accent key).
An extended duration marker appears in the scrubber bar; it looks like a marker icon
with a bar that extends along the scrubber bar.
The video and audio clip
item markers are aligned
with the sequence marker.
