Inserting Markers for Precise Editing
You can set a marker on the Timeline or in an individual clip in the Timeline to help you do more precise video and audio editing.
The marker creates a snap-point on the Timeline or on a clip that the playhead will lock onto.
This can be helpful when you're editing audio and you want a video track to begin exactly at the downbeat of a song. You can set a marker during audio editing at the downbeat so you then can add the video clip to begin at precisely that point.
You create a marker in a clip in the Viewer by moving the playhead to a point on the clip and pressing the M Key. The marker will appear as a tiny red triangular icon just below the playhead (it also will be displayed in the clip in the Timeline as a tiny red triangular icon).
In the Timeline you similarly create a marker by clicking anywhere in the gray area in the Timeline (in other words, click somewhere outside of any individual clip so the clip isn't selected) and then moving the playhead to a point on the Timeline and pressing the M Key. The marker will appear as a tiny green triangular icon at the top of the Timeline.
To delete a marker, move the playhead until it snaps into place on a marker. Then click in the menu at the top on Mark...Markers...Delete.
Note: If you created a marker in a clip, you'll need to select the clip in order to delete the marker that's on the clip. Similarly, if you created a marker on the Timeline, you'll need to click in the gray area of the Timeline in order to delete the marker that's on the Timeline.
