4 Simple Editing Techniques That Make Commercials Work

What editing techniques make commercials work?

Four specific editing techniques drive commercial success: strategic reaction shots that carry comedy, world-building sound design that establishes context, music that bridges diegetic and non-diegetic moments, and targeted sound effects that amplify comedic timing.

Great editing doesn't hinge on one big decision. Rather, it's the cumulative effect of a bunch of small ones. These four techniques came together in a recent broadcast commercial to create something that genuinely worked with audiences.

How to Use Reaction Shots for Comedy

The most critical edit in comedy often isn't the joke itself — it's what happens immediately after the punchline.

In this commercial, everything hinged on the wife's reaction to her husband's double entendre: "You don't generate the same interest." We had multiple options. Some reactions were smaller, some medium-sized. But we went with the biggest, broadest reaction we could find.

This choice required confidence that the joke actually landed. In the script stage, we weren't sure how much we'd need to help it along. But after editing, we felt the double entendre worked, so we committed to the most angry, shocked reaction possible.

Good actors will give you multiple reaction options that work. Your job is choosing what works best in the edit. Sometimes you think comedy is about getting the joke right, but the laugh typically comes from how characters react to the punchline.

World-Building Through Sound Design

What you can't see still matters. Sound design creates the world your characters inhabit, even when it's happening off-screen.

The big decision was what to put on that television. Visually, we knew they were watching something — they're eating popcorn, sitting on a couch, looking at a lit screen. But what were they watching?

We decided on a war movie. Something that sounded like a 1940s classic film where explosions sound a certain way. Not a current action movie that's violent — we didn't want to imply kids were watching something inappropriate. We wanted something innocuous but recognizable.

This choice played into the combat between husband and wife that was about to happen. The war movie became a subtle foreshadowing of their domestic conflict.

At the end, we re-established that time had passed. The crickets were going, the TV was off. The war movie was over. We used sound to show the world had changed without showing it visually.

Music That Crosses Between Worlds

Music can exist in your story world and outside it simultaneously. This technique bridges diegetic and non-diegetic sound to hit emotional moments.

Once we committed to the war movie, we found needle drop music that sounded like a classic Hollywood 1940s score. We layered it in to create urgency around the argument that was building.

But the key moment was the "dun dun dun" in the music, perfectly timed with her horrified reaction. At that point, the diegetic music from the TV became non-diegetic score to underscore her emotion.

Diegetic music comes from the world you're in — in this case, music from the TV. Non-diegetic music is soundtrack or score that's part of the film but not the story world. We crossed between those two using professional video editing emotion techniques that emphasize the most important moments.

Sound Effects That Amplify Comedy

Comedy works better when you emphasize awkward moments with very specific sound effects.

When the wife moves away from her husband after his unintentionally inappropriate comment, we added a couch squeak and clothes noise. These sounds accentuated the physical distance that represented their emotional distance.

This technique works across comedy editing. Maybe it's a little bird tweet during an awkward pause, or a chair creak when someone shifts uncomfortably. Go out of your way to look for these comedic opportunities.

The sound effect doesn't need to be big or obvious. It just needs to land at exactly the right moment to emphasize what's already happening emotionally.

These four techniques work because they support the story and characters rather than drawing attention to themselves. Professional commercial editing always serves the emotion first, and these tools help you get there faster.
