Which action will allow you to create a transition between clips in Adobe Premiere Pro?

Applying a transition effect is the correct choice for creating a visual transition between clips in Adobe Premiere Pro. Transitions are specific effects that enable smooth changes from one clip to another, enhancing storytelling and visual flow within a video project. When you apply a transition effect, such as a cross dissolve or wipe, you enable a gradual blend between the end of one clip and the start of another, making the overall editing more polished and visually appealing.

In contrast, adding an effect to a single clip does not create a transition; it modifies that clip only based on the effect chosen. An insert edit modifies the timeline by placing a new clip but does not inherently include any transitions between clips. Similarly, creating a new track allows for more organization and layering of media but does not by itself facilitate the interaction between clips that a transition effect provides. Thus, applying a transition effect is the fundamental action for establishing a visual transition in Premiere Pro.
