I have a video taken at a silent background but there is still some little noise.
I'd like to remove all the audio and then add a background music of my choice
to the video.
What is the easiest way to do so? I have no video editing experience
You need a video editing program to do that. Because you tell you have no experience, I recommend you start with a free one before spending money, to see if video editing is something you might get interested in.
In my opinion, the absolutely easiest to use and by far the best of all free editors is OpenShot (OpenShot Video Editor | Free, Open, and Award-Winning Video Editor for Linux, Mac, and Windows!)
It is Open Source (Open source - Wikipedia), free with no hidden costs for additional features.
When installed, run OpenShot. List numbers refer to numbers in screenshot:
- Select Project Files
- Click + to browse to and import your video
- Video will be added to Project Files
- Drag the video to timeline, to any free track. Be sure to add video so that beginning of it touches the red vertical line at beginning of the track
- Right click video track, select Separate Audio > Single clip
(Click to enlarge.)
Audio will be separated from video and moved to another track. Select the audio track, right click it and select Remove Clip:
Audio track will be cleared, the original audio of your video removed.
Import your music file to Project Files exactly as you imported the video, and drag it to any free track.
Usually the added audio track is not the same length than the video. If your music lasts longer than the video, go to end of timeline and drag audio track content so that it ends at the same point than video:
If your music track is shorter than video, you can add it again at the end of current audio track.
Now you can export (save) the video:
That's it! Easy, fast and free.
Note
Please notice that if you want to publish the video on social media, YouTube and such, you must own copyrights for audio and video content, or have copyright owner's permission. On my 100+ Windows videos, when I feel the video needs some background music, I use the copyright free music from YouTube Audio Library. Another free source is the Free Music Archive.
