There is a way to remove background noise from a video in iMovie. The iMovie app on your Mac provides a feature called “Reduce background noise” that allows you to minimize unwanted noise in your audio clips or video clips with audio.
To begin, open iMovie on your Mac and select the audio clips or video clips with audio that you want to work with in the timeline. You can select multiple clips by holding down the Command key while clicking on them.
Once you have selected the clips, you’ll need to access the noise reduction controls. To do this, click on the “Noise Reduction and Equalizer” button, which looks like a small equalizer icon, located in the toolbar above the timeline.
Clicking on this button will open up the noise reduction controls. Here, you’ll find a checkbox labeled “Reduce background noise.” Make sure this checkbox is selected to enable the noise reduction feature.
Once you have enabled noise reduction, iMovie will automatically analyze the audio in your selected clips and apply noise reduction settings. The level of noise reduction can be adjusted using the slider provided in the noise reduction controls.
It’s important to note that while the noise reduction feature in iMovie can help reduce background noise, it may not completely eliminate it, especially if the noise is very loud or persistent. Additionally, applying too much noise reduction can sometimes result in a loss of audio quality or artifacts in the audio.
To ensure the best possible results, it’s recommended to record audio in a quiet environment and use a good quality microphone. This can help minimize background noise during the recording process, making it easier to remove or reduce in post-production.
IMovie provides a convenient and easy-to-use noise reduction feature that can help reduce background noise in your video’s audio clips. By selecting the desired clips, accessing the noise reduction controls, and enabling the “Reduce background noise” checkbox, you can minimize unwanted noise and improve the overall audio quality of your videos.
