The edit instance movie can be used to view and trim instance rows in the sorter window. Click in a cell and press on the edit movie button in the sorter window tool bar to open the instance edit movie window.
The start and end time of the instance can be edited using the arrow buttons in the corners of the edit instance movie. To change the instance being displayed in the movie window, click in any cell of a different row. The edit instance movie will update as the cells are clicked in different rows. Turn on movie looping mode to make the make the movie play continuously, saving a few keystrokes or mouse clicks.
Pressing the back arrow at the start of the edit instance window shifts the edit instance to the previous row in the sorter. This is a wrapping type of behaviour. Refer also to “Adjusting the Length of an Instance” .
