How to Change Background Music of Videos? [4 Free Methods]

As most video editing tasks are completed on PC, this part shares two ways for you to change video background music on Windows and Mac.

WonderFox Free HD Video Converter Factory is an all-in-one video processing tool for Windows. Its user-friendly interface and self-explanatory operation make it simple for anyone, from a novice to a tech-savvy individual, to change the background music of a video. You can easily remove the original audio track and add a new audio file to the video as the background music. You can even add multiple audio tracks to the video. Not just used for background music replacement, it can also be used to add subtitles to videos, extract audio from a video, normalize the audio volume, and more.

Without further ado, let’s walk through the detailed guide on how to change background music of videos in the following content.

Developed by Apple Inc., iMovie is a video editor app preinstalled on Macs. It has many video editing features that allow users to trim, rotate, crop, and merge video clips, add subtitles, enhance video color settings, add video transitions, change the speed of clips, certainly change the video background music, and more.

If you are an Apple user and wonder how to change music in videos with iMovie, just read the following guide.

Step 1. Launch iMovie on your Mac and click “File” > “Import Media” in the top menu bar to import the source video. Once the video is loaded in the iMovie interface, drag and drop it to the timeline.

Step 2. Right-click the video on the timeline and choose “Detach Audio”. Then the background music is separate from the video, and you can click to delete it. Or you can directly mute the video by clicking the audio icon.

Step 3. iMovie provides a music library for you to choose the background music, but you can also add the local audio files or your voice-over to the video as the background music. You can press “Audio” to add the audio from your iTunes library or click “File” > “Import Media” to select the audio file from other sources.
Note: Once you drag the audio clip to the timeline below the video, there will appear a green line to indicate that the audio clip has connected to the video clip.

Step 4. Now you can edit and adjust the background music to make it the same length as the video.

Step 5. Once you have done all the adjustments, go to “Share” to export the video.

Instead of downloading a desktop video editor to remove background music from a video, you can also try some online video editors to replace the background music in videos. Here are many online video editing tools now, and I’d like to take Clideo as an example to show you how to change the video background music online free.

Clideo is one of the most popular online video editors that enables users to merge, crop, rotate, resize, trim, and compress videos. It also allows you to add music to videos. Some audio editing features like cutting and merging audio are also provided.

Now, let’s see how to change background music of a video with Clideo.

Step 1. Go to the startup page of Clideo with this link (https://clideo.com/) and click “All tools” to find and open the “Add Music to Video” tool.

Step 2. Click “+ Choose file” to import the video from your local drive. You can also click the arrow icon to select a video file from your Google Drive or Dropbox account. Wait for the file uploading process.

Step 3. After entering the audio adding page, click the “+ Add Audio” button right next to the video view window to pick an audio file and wait for the uploading process. (Here you can also add the audio file from your Google Drive and Dropbox account.)

Step 4. Now you can set the music start time while playing, and trim the audio to shorten the audio track. You can also loop the audio when the soundtrack you add is shorter than the video. Then drop the video volume to 0%.

Step 5. At the bottom left of the window, you can choose the output format or leave it as the default (MP4). Finally, press “Export” and wait for a while.

Step 6. Before downloading the final video, you can preview it to make sure everything sounds OK. Then click “Download” to save it to your devices or upload it to your Google Drive or Dropbox account. Otherwise, you can click “Edit” to return to the previous step.

Besides changing video background music on desktop/online, some mobile apps can also help users replace background music of videos on their mobile phones. You can just search for a video editor in the App Store on your iPhone or Android phone. Here I will show you how to replace the audio in videos with InShot, which is a popular video editing app compatible with iPhone and Android that has been downloaded over 500 million times.

Step 1. Download InShot and open it. Select “Video” from its home screen and choose a video file from your local folder. Tap on the green tick mark at the bottom right corner.

Step 2. Press “Music” in the bottom toolbar and click the video track to mute the original video volume. Then hit the “Music” button to add a new audio track to your video from the provided music library or your local audio files.

Step 3. After the audio track is shown on the Editor screen, press “Edit” to trim the audio track, adjust the audio volume, etc. Now, you can click “Save” in the upper right corner to download the edited video.

Well, that’s it! With the four ways mentioned above, you can now change background song of videos on Windows, Mac, online, and mobile phones as you like. You can also use them to accomplish other video edits. Hope you can now change audio in videos smoothly. Thanks for your reading. Have a nice day!
