Smoothing Out Edit Points with Dissolves

Besides the cut, the dissolve is the most commonly applied transition covering all types of editing genres. The dissolve, also called a cross-fade, is used to blend one image into another, avoiding the harshness of a scene change that sometimes comes with cuts at the edit points. A dissolve is nothing more than a progression of frames that, over the course of the transition, equally changes the percentage of opacity between the outgoing shot and the incoming shot. Therefore, in the first frame of the dissolve, the outgoing shot is 100% opaque, and the incoming shot is completely transparent. Halfway through the duration of the dissolve, each clip is displayed at 50%, an equal blend of each image. The last frame of the dissolve is where the cross-fade completes its transition, making the outgoing shot 100% transparent and the incoming shot 100% opaque. (See Figure 5.13).

The dissolve's length or duration is completely dependent on the mood you are trying to create, as well as the amount of source footage available. Obviously, you cannot hold a dissolve longer than the duration of the source footage for the clip you digitized.
