Alpha masks are typically created within video-editing applications such as Apple s Final Cut Pro or Adobe s Premiere. The process involves opening the image within the video-editing application and creating the transparency using a specific color referred to as blue or green screening using luminosity levels or actually creating a mask in an image-editing application such as Adobe Photoshop and then importing the mask. For example you could film yourself against a green screen and then mask those areas out. When you open the movie in Flash any other background you place behind the movie will replace the original green screen. They do this in the movies all the time.
