How to Write a Pre‑Lap

There are two ways a pre‑lap is written in a screenplay, depending on whether it’s dialogue or a sound effect.

1. Dialogue Pre-Lap: Write the character’s name followed by “(PRE‑LAP)” in parentheses. This signals that the line comes from the next scene but starts before the cut.

INT. LIVING ROOM – EVENING

MARY sits quietly on the couch.

                   JOHN (PRE‑LAP)
         It’s too late to change our minds now.

CUT TO:

INT. CAR – NIGHT

John grips the steering wheel, distant headlights ahead.

2. Sound Pre-Lap: Use a separate line that begins with “PRE‑LAP:” followed by a description of the sound. This can be a phone ringing, music, or anything else the viewer hears before the cut.

INT. OFFICE – DAY

Sarah glances at a blank phone.

PRE‑LAP: A phone RINGING.

EXT. STREET – DAY

A phone lies on the sidewalk, ringing insistently.

Formatting Tips:

• Place “(PRE‑LAP)” directly after the character’s name — not below it.
• Use “PRE‑LAP:” for sounds or music, not dialogue.
• Avoid confusing it with a voiceover (V.O.). A pre‑lap is grounded in the next scene’s world, not outside narration.
• Some writers drop the hyphen and write “PRELAP.” Both are used, but “PRE‑LAP” is more common.

Why and When to Use a Pre‑Lap

A pre‑lap helps connect two scenes more smoothly. It can guide the viewer through a time jump, emotional shift, or change in location. Writers use it to build tension, add rhythm, or make a cut feel seamless.

Here are common reasons to use a pre‑lap:

• To build suspense before revealing a new setting or action
• To emotionally link two scenes without stopping the flow
• To foreshadow an event or signal a shift in tone

For example, hearing someone scream (PRE‑LAP) before cutting to a dark alley creates urgency. Or in a drama, a calm question (PRE‑LAP) before cutting to a tense conversation can deepen meaning.

In editing terms, this is similar to a J‑cut — where audio from the next scene begins before the video cuts. A pre‑lap is how you indicate that edit choice in your script.

Use pre‑laps sparingly. Some script readers find too many pre‑laps distracting or over-directed. It’s better to include them only when they add clear emotional or narrative value.

Summing Up

A pre‑lap is when dialogue or sound from the next scene starts early, before the current scene ends. You write it using “(PRE‑LAP)” for dialogue or “PRE‑LAP:” for sound. It helps connect scenes, guide pacing, and set mood — but should be used with purpose and restraint. When used well, it’s a clean, professional way to shape transitions in your screenplay.
