Vimeo users have just got a new tool that lets them modify existing videos from within the Vimeo cloud by adding or adjusting the soundtrack of their movie.

The new Enhancer allows people to add any of the 50,000 music tracks from the Vimeo Music Store to their Vimeo videos directly from the site, without the need to edit offline.

In addition to the new tool, Vimeo has also signed a new partner - SmartSound - that gives Vimeo customers the ability to match a complete piece of music perfectly to the length and mood of their videos without any effort.

“The right soundtrack can make the difference between a good video and a great one," says Dae Mellencamp, the woman in charge of Vimeo. "Byintegrating SmartSound’s unique offering of customisable music, Vimeo users can now make the soundtrack to their videos as unique and personal as the video itself." 

SmartSound music is available now from the Vimeo Music Store, priced at $1.99 a track for personal use licence and $19.99 per track for a commercial license.
