This is a drag n’ drop fullscreen background with a video. The url of the video is in a variable, and must a flv file.
The video is automatically smoothed, no stairs effect when resizing.
The video scales proportionally, to prevent deformation.
You can also use a patern over the video to attenuate the effect of compression.
The transparency of the patern can be set, by a variable too.
The resizing can be by the center, just ask.
