Any free software to watermark my HD VIDEO ?

i am looking for a software that would put a watermark of my site url on my HD VIDEO and output would also be HD ...

any suggestion guys ?

I'd say the best way to do it is using VirtualDubMod. Here's a tutorial: http://forum.videohelp.com/threads/191496-Put-a-custom-watermark-on-your-video

Windows Movie Maker is also an option, but I've gotten better results with HD video using VirtualDubMod. Here's how to do it with Movie Maker: http://www.makeuseof.com/tag/watermark-videos-windows-movie-maker/
