The basic steps work the same way in every video editor

To add background music, you import an audio file into your project, place it on the timeline below your video track, and adjust its volume so it does not drown out dialogue or other sounds. Most editors let you drag the audio file directly onto the timeline, trim it to match your video length, and fade it in or out at the edges. The exact menu names and button locations change between programs, but the workflow is identical: import, place, trim, mix.

The time this takes depends on how many music tracks you want and whether you need to sync the music to specific moments in your video. A single background track takes five to ten minutes. Layering multiple tracks or matching music to action takes longer because you have to listen, adjust timing, and test the balance repeatedly.

Key Takeaways

  • Import your audio file through the File menu or by dragging it directly into the media library, then drag it onto the timeline below your video track.
  • Trim the audio to match your video length by clicking and dragging the edges of the audio clip on the timeline.
  • Lower the volume of background music so dialogue and sound effects remain clear — usually between 30 and 50 percent of full volume.
  • Use fade-in and fade-out effects at the start and end of your music to avoid jarring cuts when the video begins or ends.
  • Test your mix by playing the video all the way through with headphones to catch moments where music is too loud or too quiet.

Where to find and import audio files

You can use music from your computer, from royalty-free libraries, or from stock footage sites that include audio. Common free sources include YouTube Audio Library (built into YouTube Studio), Pixabay, Pexels, and Freepik. Paid options like Epidemic Sound and Artlist offer larger catalogs and higher-quality tracks. read the audio file to your computer first, then open your video editor.

To import the file, go to File > Import or File > Open Media, navigate to where you saved the audio, and select it. Some editors like DaVinci Resolve and Adobe Premiere Pro also let you drag the audio file directly from your file explorer into the media library panel on the left side of the screen. Once imported, the file appears in your media library and is ready to place on the timeline.

If you are using music from a royalty-free site, check the license terms before downloading. Most free music requires you to credit the artist in your video description or credits, even if the license says "free for commercial use." Read the specific license for each track — they vary.

Placing audio on the timeline and adjusting length

Drag the audio file from your media library onto the timeline. It should land on an audio track below your video track. If your editor does not have an audio track visible, right-click the timeline area and select "Add Audio Track" or look for a plus button next to the existing tracks.

Once the audio is on the timeline, you will see a colored bar representing the sound. To trim it to match your video length, position your cursor at either end of the audio bar until it changes to a resize cursor (usually a double-headed arrow), then drag inward. Trim the start if the music begins before you want it to, and trim the end if it extends past where your video ends. You can also right-click the audio clip and select "Trim to Selection" if you have marked the exact in and out points you want.

If your music is shorter than your video, you have two options: loop the track by copying and pasting it multiple times on the timeline, or add a second track that starts where the first one ends. Looping works well for ambient background music; switching tracks works better if you want variety.

Controlling volume and preventing audio conflicts

Background music should sit behind dialogue and sound effects, not compete with them. Select the audio clip on the timeline and look for a volume slider — usually in a panel on the right side of the screen, or accessible by right-clicking the clip and selecting "Volume" or "Audio Properties." Start at 50 percent and play the video. If you can still hear dialogue clearly, lower it further. If the music disappears, raise it slightly.

The goal is to hear both the dialogue and the music without one drowning out the other. This is called mixing, and it requires listening with headphones or good speakers. Play the section where dialogue and music overlap, adjust the volume, and play it again. Most editors show the audio waveform on the timeline — a visual representation of how loud the sound is. Tall peaks mean loud sections; short peaks mean quiet sections. Use this as a guide, but trust your ears more than the visual.

If you have multiple audio tracks (dialogue, music, sound effects), you can adjust each one independently. Select each clip and set its volume separately. Some editors let you create a keyframe — a point where you set the volume to a specific level at a specific moment — so the music gets quieter during dialogue and louder during silent scenes. This takes more time but creates a more polished result.

Adding fade-in and fade-out effects

A fade-in makes the music start silent and gradually get louder over a few seconds. A fade-out does the opposite — the music gradually gets quieter until it stops. These effects prevent the music from starting or stopping abruptly, which sounds unpolished.

To add a fade-in, select the audio clip on the timeline. Look for an Effects panel or right-click and search for "Fade In." Most editors let you drag the corner of the audio clip inward to create a fade — you will see a small triangle or curve appear at the edge. Drag it to the right to make the fade longer (three to five seconds is typical). Do the same at the end of the clip for a fade-out.

If your editor does not have a drag-to-fade option, go to the Effects menu, search for "Fade In Audio" or "Audio Fade," and explore it to the clip. Then adjust the duration in the effect settings. Test the fade by playing the section where the music starts or stops.

Syncing music to action and pacing

If you want the music to hit a specific beat at a specific moment — for example, a drum hit when someone jumps — you need to sync the audio to the video. Play the video and listen to where you want the beat to land. Pause at that moment and note the timestamp shown on the timeline (usually at the top). Then find that same moment in your audio file by dragging the playhead through the audio waveform until you see the peak that matches the beat you want.

Drag the audio clip left or right on the timeline to move it earlier or later. When the peak in the audio lines up with the moment in the video where you want it to hit, release the mouse. Play the section to confirm the sync is correct. This takes practice — start with obvious beats like a bass drop or a snare hit, which are easier to see in the waveform and easier to hear when they are off.

For videos with multiple scenes or cuts, you may want different music for each section. Import multiple audio files and place them end-to-end on the timeline, or on separate audio tracks that play at different times. Fade out the first track and fade in the second where they meet to avoid a jarring transition.

Testing and exporting your video with audio

Before you export, play your entire video from start to finish with headphones or speakers you trust. Listen for moments where the music is too loud, too quiet, or out of sync. Make notes of the timestamps where problems occur, then go back and adjust the volume or timing of those sections. Play again and repeat until the mix sounds balanced.

When you export your video, make sure your editor is set to export both video and audio. Most editors do this by default, but check the export settings to confirm. Look for an option that says "Include Audio" or "Audio Codec" — if it is set to "None," your exported video will have no sound. Choose a format like MP4 or MOV, which preserve both video and audio quality.

After export, play the final video file on your computer or phone to confirm the audio made it through. Sometimes audio gets lost during export if the settings are wrong, so this final check saves you from uploading a silent video.

Frequently Asked Questions

Can I use copyrighted music from Spotify or Apple Music?

No. Music from streaming services is protected by copyright, and using it in a video you share publicly — even on social media — violates the license. YouTube will mute the audio or claim the video for the copyright holder. Use royalty-free music instead, which is licensed for video use.

What if my music is longer than my video?

Trim the audio clip on the timeline by dragging its right edge inward to match your video length. If you want to keep the full song, extend your video or add more scenes. You can also fade out the music before it ends, which creates a natural stopping point.

How do I make the music quieter during dialogue?

Select the audio clip and lower its overall volume, or use keyframes to lower the volume only during dialogue sections. Click the audio clip, find the keyframe button (usually a diamond icon), and click at the moment dialogue starts. Lower the volume slider, then click again when dialogue ends and raise the volume back up. The volume will gradually change between the two points.

Why does my audio sound out of sync with the video?

This usually happens when you trim the video and audio separately without trimming them together. Check that both the video and audio start at the same timeline position. If they do not, drag one of them left or right until they line up. Play the section to confirm they are in sync.

What audio format should I use?

MP3, WAV, and AAC are the most common formats and work in all major video editors. read your royalty-free music in one of these formats. If you get a file in a different format like FLAC or OGG, most editors can still import it, but MP3 and WAV are safest.
