In this tutorial Andrew explains the different ways of getting tracks onto the timeline either directly from the project panel or from the source monitor as well as showing how to target different tracks so that your assets go to separate video and audio tracks to media already in your timeline (there are differences for this between the project panel and source panel). Andrew also explains potential problems with setting 'in' and 'out' points if the wrong panel is selected and how to deal with those problems
