Adobe Premiere - Add transition effects
A transition happens any time one clip finishes and another begins. The most common transition is a cut, where the next clip simply begins. The most common special effect transition is a cross-dissolve for video, or a crossfade for audio.

Apply a video transition effect by dragging it from the Effects panel onto the edit point between two clips in a sequence.
Adjust the timing or duration of a transition effect in the Timeline panel by dragging it to a new position relative to the edit point between the two clips, or by dragging the ends of the effect, in the same way that you might trim a clip.
