Importing Video / Audio Tracks
Video / Audio Files are imported into Multi-Track Editor one after another. Each new file added is placed on it's own track. Add a file to the Multi-Track Editor by clicking the "Add Video / Audio File As Track" button.
Video Tracks are marked by the prefix 'V' and Audio Tracks are marked by the prefix 'A', followed the track number.
The tracks are added from top-to-bottom. For example, if you add one video file and two audio files - the tracks generated will be V1, A2 and A3 and V1 will at the top, followed by A2 below it and A3 below A2.
