YouTube has launched a video-editing tool that lets you improve or make adjustments to your movies online and then upload them straight to the video-sharing site.
This makes it much easier since you don't have to polish and publish your footage at home; you can use any machine with internet access to make your movie however you want.
The new YouTube Video Editor enables users to combine multiple existing pieces of footage to create a new, longer video. You can also trim the beginning or end of a clip to make it shorter and cut out unwanted material. You can even use the editor to add soundtracks, and there's one-click publishing to YouTube so you don't need to spend time re-uploading the newly edited clip.
