Optional—Creating an MPEG-1 for DVD Group and Destination
To make it easy to use these two MPEG-1 presets with a source, you can create an “MPEG-1
for DVD” preset group using them. See
Creating Groups of Settings
for more information.

Creating MPEG-1 Output Files
Compressor provides the tools you need to create exceptional MPEG-2 transcoded files.
MPEG-2 is an internationally accepted compression standard developed by the Motion
Picture Experts Group (MPEG). MPEG-2 allows you to create broadcast-quality video files
and was designed to support high-resolution, high bit-rate video. It is the video
compression format used for high-quality video titles on DVD, HD broadcast, and home
satellite dish systems. All DVD players contain the hardware required for MPEG-2 playback.

About Standard Definition MPEG-2
Standard MPEG-2 is full frame rate (23.98–29.97 fps) and full-screen resolution (720 x 480
for NTSC and 720 x 576 for PAL). MPEG-2 has the following characteristics.
• Support for interlaced video: MPEG-2 can support either interlaced or progressive video.
Because MPEG-2 streams are generally played from a local DVD drive, rather than over
a network with variable bandwidth, video frame rate usually stays constant, and the
video normally looks completely smooth.
• No streaming support: MPEG-2 is not suitable for streaming video files over the web
because it requires a high bit rate (2 to 9 Mbps) to maintain acceptable image quality.
