You can trim transitions containing dissolves. You can trim the segments on either side of the dissolve, and you can trim the dissolve itself (that is, increase or decrease the duration of the dissolve).

The following examples use the same three-segment sequence used throughout this section. In these cases, however, an eight-frame centred dissolve has been added to one of the transitions. As the dissolve uses four head and four tail frames, the head and tail on the surrounding segments in the “before” cases have been reduced from ten to six.
