J-cut

Named for the shape it makes on a timeline. The audio clip extends left, sitting beneath the outgoing picture, so you hear the next speaker, the next room or the next scene for a beat before the image catches up. The cut stops announcing itself. That is why dialogue and interview edits use it constantly. Its mirror is the L-cut, which holds outgoing audio over incoming picture and does the same job in reverse, and both are split edits where the sound and picture cuts land at different points. On a talking-head channel a few frames of lead is usually plenty.
