What is a windows movies maker video card?

I want to make a youtube video and I want to know what a video card is and where I can find one because mine doesn't let me make any movies :'(|||A video card is a component of your computer...you can replace it, but you would have to make sure your replacement is compatible with your motherboard. Try typing "video card" or "graphics card" into amazon. Windows movie maker is not a very demanding program though- so even a cheap one should be able to handle it.
