Abstract
Video content from a layer of multiple multimedia content layers may be moved to a lowest content layer. The region of the multimedia content layer that previously contained the video content may be replaced with a transparent region. Additional layers that exist between the layer from which the video content was removed and the lowest layer may likewise have corresponding regions replaced with transparent regions. The content layers may be composited together at a display time. Accordingly, the video content of the lowest content layer may be viewed through the transparent regions, which may allow the video to be seen as originally authored. The lowest content layer may be rendered independently of other layers. In some embodiments, the content layer containing video may be performed with dedicated hardware (e.g., a GPU).
