How to take audio out of a Youtube.com video?

What is the best, simple, video software to take a video of me playing piano and record violin?

• I am in need of a video program to where I can upload a piano playing video onto it and use that video to record myself playing violin and possibly voice. I would like to be able to change the volume of the video and the recording separately.. This would be so nice to have a program like this but it seems almost impossible to find! (Imovie is so frustrating, i can't even find the play/stop button!

• Answer:

  I do not think what your trying to do can be achieved with any software package alone. Start with a video camcorder. I will say that most HD camcorders suck big time at this type of shoot, but if that is what you have, use it. If I understand your question, you want to mix together and play as one, you piano solo, your voice and a violin solo, all to play as one video. This would be a very cool video to make using picture in picture, cuts and transitions, with one sound track and many views of the 3 disciplines your doing. I have a BOSS BR 600. It has the ability to record multiple tracks then replay them as one. This just the thing you need. Visit my site http://www.asimplelife.ca/boss.html click on the links and learn more.
