Green Screen Workshop

So basically, a green screen background is used to give the editor the ability to choose what the background/location of the video will be. While filming with a green screen, it's important that there is plenty of lighting because when shadows are present, it is difficult to edit around them. Also, you need to move as little as possible because there's only a certain amount of space available to edit with while using the green screen and if the subject moves out of the area, the video won't turn out the way you want. I think it's easier to use After Effects while editing with a green screen because you can edit the background and subject to the point and it will look like clean edit.
