YouTube just got a major boost in functionality, thanks to the implementation of a few editing tools that allow people to tweak their clips without ever leaving the site.

 

 

With this newly-added feature, people can shave off some frames, change the soundtrack, stabilize or rotate their video, modify contrast and colors, and even add new effects. Once the changes are done and the result is satisfying, the edited video can be saved with the same ID, thus replacing the older version. To start tweaking, just click the "Edit video" button found on the video page.
