Creating Graphics for Drop Zones and Buttons

Assets used in drop zones and buttons do not need to conform to video aspect ratios because drop zones and buttons can be resized independently in the horizontal and vertical directions. Additionally, drop zones and buttons support a graphic’s transparency. This means you can create a graphic with irregular edges, such as a logo, and when it is assigned as the asset for a drop zone or button, the transparency will control how the graphic appears.

Similar to graphics used for shapes, drop zone and button graphics are automatically scaled to maintain their aspect ratio. If you create a square graphic and import it as an asset for a drop zone or button, it is scaled so that it remains a square graphic in DVD Studio Pro. See Shape Aspect Ratios for more information.

Note: To force the drop zone or button active area to match the graphic’s aspect ratio, press Shift while dragging one of its corners.

Getting Good Results Using Assets That Include an Alpha Channel

A video asset, either still or with motion, that includes an alpha channel can be very effective when assigned as a drop zone’s asset. DVD Studio Pro composites the asset over the menu background using the alpha channel to control the compositing.

For best results, be sure the video is premultiplied (also known as shaped). Premultiplied video will have correct soft and anti-aliased edges when used in the Menu Editor. A video channel that is straight (also known as unshaped) will have incorrect edges when composited in the Menu Editor.

If the application you are using to create your assets provides a choice, it is best to choose premultiplied video.
