What is the purpose of the Edge Selector in video transitions?

The purpose of the Edge Selector in video transitions is specifically to change the orientation or direction of the transition effect applied between two clips. This tool allows editors to determine how the transition appears on-screen, such as whether it moves from left to right, top to bottom, or in any other direction specified by the user. By controlling the direction of the transition, editors can enhance the visual storytelling of the video, aligning it with the intended mood and pacing of the sequence.

Other actions, such as adjusting brightness, adding audio effects, or modifying clip length, pertain to different elements of video editing and are not related to the function of the Edge Selector specifically within transitions. These aspects involve different tools and techniques tailored to enhance video quality, manage sound design, or fine-tune the timing of clips, marking a clear distinction from the primary role of the Edge Selector in crafting visually dynamic transitions.
