Beat Mapping to Scene Markers
If the global Video track is visible, a QuickTime movie is loaded, and the Detect Cuts
function (in the Video track) is used, the detected scene markers appear as available
mapping positions (vertical lines) at the bottom of the Beat Mapping track. You can
easily define a scene cut position as the first downbeat of a bar—by allocating it to the
bar position, as described above.
Beat Mapping to Markers
If the Marker track is visible, you can use the desired marker as a mapping position
(vertical line at the bottom of the Beat Mapping track) by clicking on it. Shift-click to
assign multiple markers as beat mapping positions. Once done, you can hide the
Marker track.
