Sony Vega
http://www.sonycreativesoftware.com/products/vegasfamily.aspMost of the cartoon/anime movie even WinX Club are make by using Sony Vega, The most powerful video editing software in the world, I recommended not using this unless you have taken some Video Animation course etc, Cause it very Complicated, but it does amazing effect, like you can merge 4 video into 1 single video ( Example WinX Club Transformation )
Free 30 Day trail too by the way
