How to remove background noise from video — without touching the picture
Why we don’t re-encode your video
Re-encoding costs picture quality and time, so we copy the video stream as it is and replace only the audio.
An MP4 or MOV holds separate video and audio streams. To remove background noise from a video, we lift the audio out, clean it, and put it back next to the original picture, bit for bit. Nothing about the picture is re-rendered, so you keep the quality you shot.
Wind noise: prevent it, then clean it
A windscreen on the mic prevents more wind noise than any software can remove afterward.
Use a furry windscreen outdoors, turn your back to the wind so your body shields the mic, and keep the camera or phone close when you talk.
| Situation | Before you shoot | After upload |
|---|---|---|
| Breezy day | Foam or furry windscreen | Cleans up well |
| Strong gusts | Body between the wind and the mic | Reduced, not removed |
| Moving vehicle | Mic close to the speaker | Engine drone cleans up well |
| Busy street | Get closer; face away from traffic | Traffic pulled well back |
Noise or music? Pick the right tool
If the sound under your voice is music, use music removal; if it’s wind, traffic or a room, you’re in the right place.
A soundtrack needs separation instead: Remove Music from Video keeps the voice and returns the same MP4, so you can replace the music or keep a little under a fader. If a clip has both, remove the music first, then clean what’s left.
