Thanks to a link I found on another page,   Windows Live Movie Maker - Use Slow Motion
http://www.youtube.com/watch?v=pGCjOqV974g I know how to isolate a clip so that I can work on the it. I sped up a clip 4x and it came out jerky, like flipping an on- off switch, the audio is affected, too. So two questions: Is there a way to smooth out the video clip, within the movie? And, how do I delete the audio? I haven't explored the audio in Movie Maker 2012 yet. TIA
