Stock Footage & PhotosFor some scenes, it will be impossible to get

your own background video or photos. If you or your students need to get the image off the web, make sure that they choose a “large size” image so that it doesn’t appear pixilated in the video. (This is probably also a good time to talk to your students about Creative Commons.)

Go through the controls 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 .•The transparency slider fades out your foreground image.•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.
