Editing and Cropping Clips
Youtube / Google has really simplified this process.
First Just drag the Clip to the bottom video bar.
Here you can not add music from your collection, but from youtubes. Youtube a huge collection of titles that has the right to use (legally).
Just click the plus button to add the song or drag it to the music bar.
Just add a title and click Publish
This video editor is a good video editor for the Cloud. By no means is this Pro or anything, but for the casual user of youtube it is a match made in heaven. I hope youtube pulls this out of the TestTube and in to youtube editing arsenal.
This is the video I made while making this review
