Popular video-sharing site Vimeo has launched a new Enhancer tool that makes it possible to seamlessly add more than 50,000 music tracks from the Vimeo Music Store directly to online videos, the company announced today.

Vimeo has always focused on bringing the highest-quality experience to online videos and its emphasis on quality separates itself from YouTube. Now, with the Enhancer tool and a new partnership, Vimeo builds on that reputation by making it easier to add a soundtrack to an already uploaded video, change audio levels, and change the start and end times of a track.

The company also has added a new music partner with SmartSound that will let users add about 4,000 customizable tracks to their videos. The offering is unique in that you can do a lot to change the mood of SmartSound track, including speed it up, slow it down, or change the musical arrangement. SmartSound tracks cost $1.99 per track for a personal use license and $19.99 per track for a commercial license.
