To achieve a seamless transition where the audio from the next shot begins before the video, or the audio from the current shot extends into the next, which advanced editing cut technique should be used?

To achieve a seamless transition where the audio from the next shot begins before the video, or the audio from the current shot extends into the next, the advanced editing cut technique used is a Split Edit. A Split Edit is a type of transition where the audio and video edit points are separated, meaning they do not occur at the exact same moment. This technique is typically broken down into two specific types: the J-cut and the L-cut. Both are named for how their audio and video waveforms appear on an editing timeline relative to the visual cut point.

A J-cut is used when the audio from the *nextshot or scene begins *beforethe video cuts to that shot. Visually on an editing timeline, the audio track of the incoming clip extends backward, underneath the video of the preceding clip, resembling the shape of the letter 'J'. This technique allows the audience to hear sounds from the upcoming scene, such as dialogue, music, or environmental noise, before they see it. For example, hearing the distinct sound of a distant train approaching, or a new character's voice, a moment before the video cuts to show the train or the character, prepares the viewer for the change and guides their attention smoothly.

An L-cut is the opposite: the audio from the *currentshot or scene continues to play *intothe next shot, while the video has already cut to the new scene. On an editing timeline, the audio track of the outgoing clip extends forward, over the video of the incoming clip, forming a shape resembling the letter 'L'. This technique is often used to maintain continuity and provide a natural flow in dialogue or narration. For instance, a person might be speaking, and the video cuts to a reaction shot of another character, or to a different angle, but the first person's voice continues uninterrupted for a few more words before the audio also transitions. Both J-cuts and L-cuts are powerful tools for enhancing the narrative flow, creating a sense of natural progression, and enriching the audience's experience by subtly manipulating their perception of time and space across edits.
