I was trying to find freeware which will silent videos audio track and add another one. I tried some of freewares like - wax , windows movie maker, avidemux ( linux video editor on windows ). Maybe they are good and maybe im not so experienced for the freewares but i found better free ware for myself - jaycut.com . It is website which contains java video editor, and so you can edit videos online.

Fueled by a passion for web video and creativity, JayCut was founded in 2007 and has since worked with some of world’s leading brands and received several prestigious awards.
In early 2006 we started asking ourselves if web video couldn't be about more than just consumption. We wanted to add creativity into to the equation. Nine months later, in December 2006, we had laid the foundation for what would come to be the world's most advanced technology for online video editing. The company was founded early 2007 and since 2008 we license the video editing tool to other companies and websites.
Today, JayCut is a privately held company based in Stockholm, Sweden. Our customers include some of theworld’s leading brands, and the company and technology has received some of the most prestigious awards in the industry. But our firm belief is that we've just scratched the surface of what web video can be.
Ask yourself what would happen if anyone could edit video, anywhere, with any mobile device, using any media on the web and finally publish the result to any device or website. Join us in starting this creative revolution!
