When editing a dialogue scene, how does an 'L-cut' specifically help maintain audio continuity while visually transitioning to a new shot?

An L-cut is an editing technique where the audio from the preceding shot, referred to as the outgoing shot, extends into the beginning of the subsequent shot, which is the incoming shot. While the video cleanly transitions, or cuts, to the new shot, the audio from the previous shot continues to play for a brief duration. In a dialogue scene, this specifically helps maintain audio continuity by allowing the voice of a character who is speaking, or any associated sound, to flow uninterrupted across a visual cut. For example, if a character is speaking and the editor transitions visually from that character to another character's reaction shot, an L-cut ensures the first character's dialogue continues to be heard for a moment over the image of the reacting character. This technique prevents an abrupt halt in the audio that would occur if both the audio and video tracks cut simultaneously, known as a straight cut. By having the audio overlap the visual transition, the L-cut creates a smoother, less jarring experience for the audience, ensuring the conversation feels continuous and natural, and allowing the flow of information and emotional connection to remain unbroken despite the change in visual focus.
