Definition of L cut:  The audio from a preceding scene carries over the image of the following scene.

Definition of J cut:  The audio of the next scene precedes the shot change.

J cut: The next scene’s audio plays before the current footage changes.

L cut: When the audio from the previous scene continues to play over the footage from the following scene.

J-Cut

An Editing technique used for scene transitions or within a scene which the audio of the next scene or shot precedes the image change.

An example of this can be found in Scott Pilgrim’s opening scene, where Kim’s dialogue begins over the ending of a mid-shot, and J cuts into her in the kitchen.

L-Cut

A Variant of a split edit film editing technique in which the audio form preceding scene overlaps the picture from the following scene.

An Example would be this scene from Fear and Loathing in Las Vegas, where the echoing voice of the receptionist L cuts over our protagonist.

In a J cut, the next scene’s audio plays before the image changes. With L cuts, the audio from the preceding scene carries over, and then the visuals shift.

Using a J-cut or an L-cut is all about keeping the flow of the edit moving without becoming boring. If a J-cut or L-cut is performed properly, then the audience will never notice it taking place. This same theory is really true for any editing technique.
