How to remove background noise from a video on Windows 10
Phones not only take great photos, but they can also record HD video. The only problem is that while the camera is great, there isn’t anything you can do about background noise while you’re recording. If you’ve recorded a great video that has background noise, e.g., wind, traffic, the sound of someone breathing, you can remove it in post-production.
Remove background noise from video
There are three steps to removing background noise from a video’
- Isolate the audio.
- Remove noise from the audio.
- Add the audio to the video, and mute the original, noisy audio.
We can do all three with free apps.
1. Isolate audio
In order to isolate the audio, you need to;
- Download and install Audacity.
- Drag & drop the video file onto Audacity.
- You will see the audio reflected in wavelength form.
2. Remove noise from audio
In Audacity, you need to;
- Select a part of the audio that has noise but no dialog. Click and drag it over the noisy part.
- Go to Effects>Noise Reduction.
- Click ‘Get Noise Profile.’
- Double-click the wavelength to select it all.
- Go to Effects>Noise Reduction.
- Click OK.
- Repeat until the noise is all gone.
- Go to Effects>Amplify.
- Click OK.
- Go to File>Export>Export as MP3.
3. Add the audio to the video
We now have to add the quiet audio file to the video. We’re going to use the Video Editor on Windows 10.
- Open the Video Editor on Windows 10.
- Give your project a name.
- Add the video to the project library.
- Add the video from the library to the timeline.
- Right-click the video, and select Volume from the context menu.
- A volume slider will appear on the video’s thumbnail on the timeline. Reduce the volume to zero.
- On the video editor, click Custom Audio at the top.
- Select the audio that you exported from Audacity.
- Click Done.
- Click Finish Video.
- Select the quality you want to export the video in.
- Play the newly created video, and all noise from it will be gone.
Conclusion
Unfortunately, there is no way to reduce noise in a video while it’s being recorded. If you’re recording outdoors, it’s always a good idea to record the audio independently in addition to recording it with the video. It gives you better options for reducing noise. If you’re recording indoors, you can do quite a bit to reduce noise; make sure there are no fans nearby, and there isn’t any electric item that tends to ‘hum.’
Yes! Super simple, worked as i hoped. Thank you!
