J cut
A J cut is a variant of a split edit film editing technique in which the audio from a following scene overlaps the picture from the preceding scene, so that the audio portion of the later scene starts playing before its picture as a lead-in to the visual cut. Also called an audio lead or audio advance.
The name of the cut refers to the shape of audio and video pieces of the second of two scenes cut together in most non-linear video editing programs.
