Visual effects - green screen

For those readers who have never study about film and animation, have you ever wonder how a Hollywood movie be done? Have you ever seen those people acting in front of a big green screen or green background? Actually not only Hollywood could do that, we can do that too! It's pretty simple, just take yourself a video, and then buy a green cardboard, and use a software called after effects and lastly remove the green background, there it is....




















This is one of my visual effects miniature assignment actually, any thought guys? :)
