This video is great, but the audio in this preview version is not in the purchased video. In fact, it has no audio at all. I had to find the Star-Spangled Banner off of iTunes and then sync it to the video. Since I could not find the EXACT version that is used in the preview, the timing was not correct. I had to take the time to painstakingly line up the video and audio. With the audio that is in the preview it makes it seem like false advertising.
