Using Sound Effects in Video Editing: Whoosh, Risers and Impacts
Published:
What do sound effects do in an edit?
Viewers feel every cut in a short video. A sound effect gives the cut a reason: a sound heard as the picture changes turns a random jump into a movement.
Not every cut needs a sound. Keep effects for the moments that matter and those moments stand out. If there is a sound every second, people soon stop hearing any of them.
Whoosh: land the peak on the cut
A whoosh rises slowly, reaches a peak and fades. A common mistake is placing the start of the sound on the cut. Put the loudest point on the cut instead, so the sound begins just before it and peaks as the picture changes.
Choose the length to match the speed. A quarter-second swish is enough for a fast slide, while a softer one-second whoosh feels more natural on a slow scene change. If the picture moves left to right, a sound moving the same way strengthens the motion.
Riser and impact: build tension, then release
A riser tells viewers something is coming, so the ending matters: the moment it stops should land on a cut, the frame where the product appears, or a large piece of text. Most risers end at their strongest point, and if that point falls on nothing the sound is left hanging.
Put the impact on that moment. A very short silence just before the hit makes it feel stronger than it is. Use impacts sparingly too; one or two in a video are enough.
Pop and click: small movements on screen
A short pop or click works for text, cards or icons appearing on screen. These sounds are very short, so they need to land exactly on the first frame of the movement. A pop that is a frame or two late feels like lag.
When items appear one after another, change the pitch slightly or alternate two similar sounds rather than repeating one. In app and software demos, click and notification sounds explain what is happening on screen without words.
Levels: keep the voice in front
If a video has speech, that is the most important sound. Keep effects below it; sounds from ready-made packs usually arrive loud, so you will often need to lower them by 6 to 12 decibels. If there is background music, dipping it briefly at the effect keeps speech and effect from blending together.
Do the final check on a phone speaker. Deep impacts and sub-bass mostly disappear on small speakers, and an effect that sounds great on headphones may not be heard at all on a phone. Platforms such as YouTube turn down videos uploaded very loud, so pushing the level to the limit gains nothing.
Choosing files: format and license
Use WAV in your edit when you can. WAV is uncompressed, so cutting, lowering or speeding up the sound does not reduce quality, whereas an MP3 gets compressed once more on export. Files at the same sample rate as your video, usually 48 kHz, cause the fewest problems.
Always read the license of the sound you download. "Royalty-free" usually means you do not pay per use; it does not mean the sound belongs to nobody. If you will use it in client work or ads, make sure commercial use is clearly allowed.
