EDIT ING of the edit and the start/end frame of the clip will be defined by the `in' and `out' points that have previously been set. Extending/Reducing Clips by Dragging Clips can be made longer or shorter by grabbing hold of either end and dragging the length in either direction. 1 Choose a clip in the Timeline that you wish to extend or reduce. Position the Pointer and let it hover over the center of an edit point or the area where two clips meet. A symbol with two vertical lines and two horizontal arrows will appear. 2 If you wish to reduce the length of the clip drag the end of the clip into itself (using the symbol with two vertical lines). A display will appear to the right showing the overall clip duration and the trim adjustment in seconds and frames.
