To place markers within the media, open it in the Trimmer, create your marker and click the Save Markers/Regions button. When placed on the timeline, the markers will show on the event if you have View> Event Media Markers on.
Yep, I knew that I could open the trimmer and mark 'em there, but I want to place marks (as you can in the trimmer) on an object but do it on the timeline.
What I have is a project that I marked on the timeline, now I want to take the object to another file but do not want to have to mark the good stuff again, guess I should render?
