Green screen- Editing

The Chroma Key Color Transition in Video Edit Magic is one such tool.  Also known as the Green or Blue Screen technique, it can help you create truly startling illusions.  You may never have visited the Taj Mahal or the Pyramids of Egypt but with this technique you can at least make it seem that you actually did,
There are many different Chroma Key editing techniques and Once you have decided on the color of the screen, the next step is to shoot the subject standing in front of it.  If you are aiming for perfection, make sure that the subject has a well defined outline.  There should not be small parts of the clothing or even hair hanging loose as you want a sharp separation from the background.
