We recommend that you make your buttons at least 72 × 60 pixels, or 300 × 80 for larger buttons. without loss of quality, but if you make a small button much larger, you lose resolution. Creating irregularly shaped buttons Adobe Photoshop lets you create files with background transparency. You can therefore create nonrectangular buttons, even buttons with holes in them. Photoshop also uses layers to separate parts of an image; you can use these layers to create multiple buttons in the same file, with one button in each layer. In the New dialog, click the Transparent radio button: This creates a document with no background. Create the artwork for a single button in Layer 1. sonic. com Preparing Files for DVDit! 4 3.

The DVD video format uses a subset of the MPEG standards, permitting only specific images resolutions, frame rates, aspect ratios, etc. supports MPEG-1 and MPEG-2 video files, but you cannot mix the two in a single project. also supports MPEG-1 Layer II audio, which it converts to PCM or Dolby Digital audio when you create a disc. DVD-compliant MPEG files can contain: · A single stream of either video or audio (an "elementary stream"), or · One MPEG-1/MPEG-2 video stream and one MPEG-1 Layer II audio stream (a "program stream") DVDit!Use the following parameters when creating MPEG video and audio files.
