An Alpha Channel is an extra layer or "channel" in a video or photographic element that is transparent. This allows the editor to key over the element and control the opacity of the overlay. You see these kinds of elements used on TV all the time. Whenever a news program identifies a reporter on the scene they use a "lower third", an element across the bottom of the screen usually with text or information composited over it. ESPN, News Shows and Information programs use them a lot. MEP14+ is one of the few NLE's that have this capability in it's price range. All of the expensive editors can do this. You will not find this capability in Windows Movie Maker™ and other home movie editors. And of course film makers have always had the ability to overlay.
For you, this will raise the bar on your video productions taking you to a whole new level of quality. You can now do all the stuff TV stations and networks can do, the power is in MEP14+!
There are several companies you can buy these video elements from. In this production I used Digital Juice. If you have Photoshop™ or any graphic program that will work with transparent layers, you can make your own alpha elements too! Look Here & Here. Below the video is a list of places to get great elements like those used in this episode. Time; 15:47
