Youtube allows video editing:
Video editing was a much awaited feature for the Youtube users. It is available at: http://www.youtube.com/editor

Features:

• Combine multiple videos you’ve uploaded to create a new longer video
• Trim the beginning and/or ending of your videos
• Add soundtracks from our AudioSwap library of tens of thousands of songs
• Create new videos without worrying about file formats and publish them to YouTube with one click -- no upload necessary
