FROM IDEA TO DOWNLOAD

Here’s how to make it yours

01
Choose the video
Add the footage to keep. Its duration sets the replacement soundtrack length.
02

Choose your music. Replace is selected by default: original dialogue and background sound are replaced too.
03
Check the new soundtrack
Create the audio preview and then the finished video. Watch before downloading the MP4.

ONE WAY TO USE IT · ILLUSTRATION

Your footage, a different feeling

Give a product clip music instead of room noise. Replace the soundtrack without recutting the picture and check that it lasts for the whole clip.

Try your version

Video + original soundSame video + your music

Replace audio deliberately

Replacement changes the entire original soundtrack, not just its background noise. Any original speech is removed too.

Choose Keep all original sound to retain it and add music at a fixed balance instead. Selective voice isolation and noise cleanup are separate tasks; replacement is not automatic ducking or restoration.
