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!supports both elementary and program streams. Use the following parameters when creating MPEG video and audio files. MPEG-1 video: Maximum GOP size: (see "What is a GOP?" on page 7 for more information) Frame rate: Aspect ratio: Bit-rate: Filename extension: 18 frames (NTSC) 15 frames (PAL) 29. 97 Hz (NTSC) 25 Hz (PAL) 4:3 1. 15 ­ 1. 856 Mbps . m1p, . m1v, . mp1, . mpg, . mpeg, . mpv MPEG-2 video: Maximum GOP size: (see "What is a GOP?" on page 7 for more information) 36 fields/18 frames (NTSC) 30 fields/15 frames (PAL) Some encoders generate MPEG-2 streams with variable GOP sizes. supports these streams, providing the GOP size does not exceed the above limits.

See "WAVE Audio" on page 8 for the audio parameters. sonic. com Preparing Files for DVDit! 7 WAVE Audio WAVE (Windows audio) files contain either uncompressed PCM audio or compressed audio.
