Video in Flash
Although video is discussed on more than one occasion throughout this book, it is important to note a major improvement for video in Flashthe alpha channel.Now Flash can import, convert to FLV, and play back video with an alpha channel, allowing developers and designers to quickly add video to their Flash content and still be able to see what is behind the video.As you can see in Figures 1.11 and 1.12, both use the same video, yet have different backgrounds. This was easily done because the video itself has the background taken out.
Figure 1.11. You can see the woman walking in front of platform 9 3/4.
Figure 1.12. This time, the woman is walking in front of a text field, with highlighted text, which means the user is interacting with it as the video plays.
