The background color (Stage color) of a SWF file can be set to transparent. The background color or image of the HTML page that contains the SWF file shows through. This technique allows layering of SWF content with DHTML (Dynamic HTML) content. Not every web browser handles transparency in the same way. Be sure to test your SWF file in all browsers that you want to enable your audience to use. Most Linux browsers do not support Animate transparency.
transparent — The SWF content is layered together with other HTML elements on the page. The SWF file background color (Stage color) is transparent. HTML elements beneath the SWF file are visible through any transparent areas of the SWF, with alpha blending. This option reduces playback performance compared to wmode=window or wmode=direct.
Chrome 31 now supports video alpha transparency in WebM. In other words, Chrome takes the alpha channel into account when playing green screen videos encoded to WebM (VP8 and VP9) with an alpha channel. This means you can play videos with transparent backgrounds: over web pages, images or even other videos.
