How to make a video for Youtube

[Danaldinho]

I am wanting to know how to make video which i can upload on to Youtube on the Apple iMac. I used to use Windows Movie Maker on my laptop with Vista, but now I can't figure out how to do it on the iMac.

I want to add a picture then a music song running over that.

Thanks
