What happens if the music is longer than the video?

The music ends where the video ends. The part that runs past the video is cut off.

Can I keep the original sound and add music on top?

Choose “Mix” under “Sound” and the music is layered over the original sound. If the video has no sound, only the music is added.

How to use Add music

What it does

Put a music file on a video. You can replace the video's original sound with the music, or mix the music over the original sound. The video is processed on your device and is not uploaded.

Step by step

Drop a video file onto the page, or click to choose one.
On the “Music” tab, click “Choose music file” and pick the music file to add. If it isn't an audio file, or it can't be opened, a message appears.
Under “Sound”, choose “Replace” or “Mix”. The default is “Replace”.
Set “Music volume” between 0% and 200%. The default is 100%.
Click “Add music”. When it finishes, use “Save” to download the file, or “Keep going” to pass it to another tool.

Good to know

“Replace” removes the video's original sound and uses the music instead. “Mix” layers the music over the original sound. If the video has no sound, only the music is added.
The result ends when the video ends. Longer music is cut off, and shorter music leaves the rest silent. The music is not repeated to fill the gap.
“Music volume” applies only to the music you chose.
The result is always an MP4 (H.264 video, AAC audio). The video is re-encoded too, and only the first video track is included.
The first time, the video engine (about 32 MB) is downloaded. How long the job takes depends on the length of the video and on your device.
The file name is the original name followed by “-music”, for example trip-music.mp4.
