A sound bridge is an editing technique used to transition from one scene to another through sound. Sound bridges, also called an audio bridges, allow filmmakers to transition in or out of a scene by "bridging the gap" with audio. Sound bridges connect two scenes allowing audio from a succeeding scene to play over the preceding scene before the next shot is shown. The technique used to achieve this is known as a J-cut. When the sound of a scene carries over into the next scene, that's an L-cut.

Types of sound bridges

There are various types of audio bridges depending on what sound is being used to carry over from shot to shot. Check out this video by Film Editing Pro that analyzes the different types of sound bridges and why they are used. 

How to Transition Between Scenes with Audio Editing

1. Dialogue sound bridge

A dialogue sound bridge allows the dialogue from the next scene to play prior to a visual cut to the next scene. This is often used as a means to connect the lines of dialogue to the image of the preceding scene.

Dialogue sound bridges smooth out the transition from scene to scene. It can also be used to reflect a character's thoughts, as a means of foreshadowing, or to engage the audience’s curiosity.

In this video, we break down a number of video editing transitions but there is also a section on two of the most common sound bridge techniques: the J-cut and the L-cut.

2. Sound effect sound bridge

The next type of sound bridge is the sound effect sound bridge. This type of sound bridge carries the sound design or sound effect from the succeeding scene over the first scene.

This can create both drama and intrigue depending on the sound effect that the audience hears. What is that sound? How does it connect to this scene? What is about to happen? You can see this in action in the opening scene transition of Saving Private Ryan.

3. Music sound bridge

Lastly, there is the music sound bridge which, you guessed it, uses the film's score or soundtrack to transition from one shot or scene to the next. This is effective at creating anticipation in the audience. Quentin Tarantino uses this to perfection in the opening scene of Reservoir Dogs. Then again, the way Tarantino uses music so intuitively and effectively is no surprise.

When to use a sound bridge

You might be wondering “What is a sound bridge in film used for?” The answer is that it depends on what you are trying to achieve. Audio bridges should be intentional. Using them on every scene transition can make them less effective.

1. Draw focus to a sound

Audio bridges are effective at directing the audience’s focus on a specific sound. This is especially true for dialogue sound bridges. If there is a piece of opening dialogue from a succeeding scene that connects to the prior scene, an audio bridge can bring attention to this important line. SPOILERS AHEAD!

In the movie Parasite, a key piece of information is the fact that the housekeeper is allergic to peaches. To underscore this vital piece of information, a sound bridge is used to transition between two scenes and utilize the dialogue as a voice over.

2. Create curiosity

Using a sound bridge for a specific sound effect can also entice curiosity in the audience about the following scene. What is that sound? What are we about to see? A great example of this can be found in The Matrix. Listen for the sound of the alarm clock as it grows louder and louder prior to the cut.

3. Smooth out jarring cuts

Lastly, sound bridges are an effective and simple way to create smooth cuts. Cuts can often be jarring especially when there are a lot of sounds involved like crowd noises or ambient sound.

Using a sound bridge can smoothen these rough transitions out.

Remember, these are only a few reasons to use sound bridges. Filmmakers have found endless ways to use sound bridges to tell their stories. In There Will Be Blood, one of Paul Thomas Anderson’s best films, a sound bridge is used to smooth out the jarring jump in time between a dissolve.

If you are still wondering when you should use a sound bridge, ask yourself a couple of these questions. Is the cut between scenes abrupt and distracting? Is there a connection between the two scenes that the audience should be aware of? Can you generate curiosity about the next scene through its dialogue or sound effects? 

If you answered yes to any of these, try out an audio bridge. Sometimes you don’t know how effective a sound bridge is or when it is needed until you put one into your edit.
