Flash 8 with alpha video codec functions like a pixel filter, which is to eliminate the pixels or make them transparent or translucent! Video virtually, is a series of framed images put together, one after another, to simulate motion and interactivity, and is often transmitted by number of frames. If we take video as something static, then it can be interpreted as sets of images. Every image is composed with pixels, which are considered either completely transparent or not transparent at all, with no gradations of opacity. If you use alpha, all non-transparent pixels would still reveal the underlying content. However, if your original video is with alpha, with Flash 8 with alpha video codec, Flash Video MX Pro will keep the original transparency of your video for video composing later.
