Research - Green screening

General run down of what Green Screen is

Green screen technology is the basis of the effects seen in everything from the latest Hollywood blockbusters to the weather forecast. The idea is simple. If you shoot a video with a single coloured backdrop (blue or green is often used) Pinnacle Studio allows you to make that colour transparent - replacing it with any other video clip, graphic or still image.

With green screen, it's simple to superimpose anything or anyone into any shot. You can transport yourself to the moon, appear in your favourite film, or make a presentation along with all the relevant facts and figures...
You can use any single colour, flat object as a screen.

If your backdrop doesn't go to the edges of your frame, add a picture-in-picture effect and use the cropping sliders to remove the unwanted edges of the screen.
Controls: The Chroma key controls can be a little daunting if you've never used then before, but you should go through them pretty much in the order they appear. Start by selecting the colour with the eyedropper. Then move the colour tolerance up until most of your background vanishes. Next, use the saturation minimum control to tidy up the key - so that everything in the background is removed. Use the softness control to adjust the strength of the background image (bringing it down just a little preserves the shadows on your backdrop if you want them). The transparency slider fades out your foreground image and the Spill Suppression control acts on the edges of your objects, removing any green fringes or hues that can appear 
on complicated edges or semi-transparent objects.
