The In/Out points, displayed on the timebar by [ and ] brackets, can be set in either of the editing modes to define the selection. In the timebar, a colored bar will show between these 2 brackets to better outline the area selected. In drag and drop mode , they are an easy way to define a selected region.
It is important to remember that a highlighted area overrides the In/Out points. That is, if a highlighted area and In/Out points are both set, the highlighted area is changed by editing operations and the In/Out points are ignored. But if no region is highlighted, the In/Out points are used. To avoid confusion, use either highlighting or In/Out points but not both at the same time.
To set In/Out points, in the timebar move to the position where you want the Insertion point and click the In point icon or one of the [ or < keys. Then move the insertion point to a position after the In point and click the ] or > or the Out point icon. You can use these same icons or keyboard characters to toggle In/Out points on or off.
If you set the insertion point in another place when In/Out points are already set, that existing point will be repositioned when you click the In/Out icon or keyboard equivalent. If you click on In/Out points while a region is highlighted, the insertion point will be ignored and In/Out points will be set at the beginning and at the end of the highlighted area.
When you select either the In or Out point on the timebar, the insertion point will move to that location. Note that when the insertion point is at the exact position of an In or Out point, the bracket will change color making it easy to see that you are exactly at that spot.
If only the In point is set, when you click the In point icon the In point will be deleted. If only the Out point is set, when you click the Out point icon the Out point will be deleted. Holding the Shift key while clicking on an In/Out point, the area between the insertion point and that In/Out point will be highlighted or extended to that In/Out point if already highlighted.
An easy way to turn off the In/Out points if both are set, is to double click on the [ icon in the toolbar. If you have already set the In and Out points, and then move the insertion point anywhere to the left of the Out point, a LMB click on the [ icon will move the In point to the location of the insertion point. In the same manner if you move the insertion point anywhere to the right of the In point, a LMB click on the ] icon will move the Out point to that new position. However, if you move the insertion point for either the In or Out point beyond what makes sense to designate In/Out points, the bracket you clicked on will be moved to the insertion point and the other bracket will be eliminated. That is obviously because the In point has to come before the Out point on the timeline.
Some of the useful operations concerning the In/Out pointers are listed next.
