Creating Marker Durations In Final Cut Pro
Usually, when you hear of setting markers in Final Cut Pro, you are simply marking a single frame to signify that something should happen at this point in your sequence, such as a soundeffect or the beginning of a music track. Did you also know that you can set a duration for a marker, enabling it stretch across multiple frames? You can set a marker duration for notation that an area is marked for a change in color correction or that audio needs to be tweaked in a certain area.

Creating A Duration For a Marker
1 Create a marker at the head of the area that you wish to mark by placing the playhead at that position and pressing the M key on your keyboard.
2 After you have created the marker, move the playhead to the right of the marker, where you wish for the duration to end.
3 Go to Mark > Markers > Extend and it will stretch the mareker to the playhead position.
