How to Add Music to a Video:Sources and Tradeoffs

Quick steps: Rough-cut the video; import music or use a library/generation feature the product explicitly provides; put it on a separate track, trim it and set level/fades; export and listen on the target device. Confirm that the audio terms cover your platform and use before publishing.

Choose a music source

Availability inside a platform does not automatically mean cross-platform rights. Having a downloaded file also does not establish every publishing right. Check the license against the intended source and use.

General steps for adding music to a video

1. Rough-cut the edit first. This lets you plan music around the actual runtime instead of rebuilding audio points after picture changes.
2. Import or generate music. Follow the current official steps for adding a file, choosing a library track or describing the music you need.
3. Put music on a separate track. Trim the in and out points and set level/fades. With voiceover, listen section by section to make sure speech stays clear.
4. Preview against the picture. Check that music enters, changes and ends naturally; do not judge only by listening to the audio file alone.
5. Export and listen again. Check the final file’s level, length, format and expected tracks. Confirm device-specific controls in the software’s current help.

In Aixcut, you can generate background music from custom instructions. Music and voiceover are separate tracks, with independent volume and fade controls; music can be generated or trimmed to video length and saved for reuse across projects. Generation does not require a membership and uses account credits, with consumption varying by task difficulty.

Common fixes

• Voiceover is hard to hear: lower the music and check the export on a phone speaker.
• The music ending feels abrupt: adjust the out point or fade so it resolves with the picture.
• You cannot find a control: use the current official help for your device and software version instead of copying an old menu path.
• You plan to publish on multiple platforms: verify that the music license covers each channel, account and commercial use.

Frequently asked questions

How can I add background music to a video?

Add a music file or choose an available source in a video editor, place it on a separate track, trim it and set its level and fades. Preview it with voice and picture before export, and check the source’s usage terms.

How do I add music onto an iPhone video?

Open the video in an editing app on the iPhone and add audio using that app’s current official instructions. Controls and available libraries vary by app and version; review the mix and intended-platform rights before exporting.

How do I add music to my phone video?

Import the video and audio into a mobile editor, or use a library/generation feature the app explicitly provides. Put music on an audio track, adjust length and level, and export. Follow current official help for the device and app.

What is the best free app to add music to a video?

There is no single best app for every device, audio source and use. Compare whether the current free plan supports your audio format, track editing and export, then check watermarks, plan limits and music rights. Test with a short video and inspect the export.
