The L cut is a variation of the split-fiction film editing technique where the sound from the previous scene overlaps with the picture in the next scene, so the sound is cut off after the picture and continues to play at the beginning of the next scene.
L-cuts are the exact opposite of J-cuts because the video is edited so that the video’s image changes from one shot to another but the initial shot’s audio continues into the next clip. Like a J-cut, an L-cut has its name because of its appearance in the timeline of your editing software.
The name of the cut refers to the shape of the audio and video segments cut together in the second of the two scenes when done on analogue film[a], and this technique has been practiced since the first advent of sound film.
L-cuts are made up of three things:
1) Primary shot video,
2) Primary video audio and
3) B-roll or other video clip.
Depending on how these three elements are arranged, you can create an L-cut. The most successful J-cuts/L-cuts example of all time used by Director Stanley Kubrick in 2001: A Space Odyssey.
