Creating MPEG-1 Output Files
Compressor provides the tools you need to create
exceptional MPEG-1 transcoded files.
MPEG-1 is an internationally accepted compression standard developed by the Motion
Picture Experts Group (MPEG). MPEG-1 allows you to create VHS-quality video files and
was designed to support SIF (Standard Interface Format) resolution non-interlaced
(progressive) video using relatively low bit rates (Compressor supports 0.5 Mbps to
2 Mbps). It also allows you to create compressed 1-channel and 2-channel audio.
This chapter covers the following:
 Common Uses for MPEG-1 (p. 115)

Common Uses for MPEG-1
MPEG-1 is a widely adopted standard, so it can be used in many different ways. Here
are a few:
DVD, VCD, and CD ROM
MPEG-1 is the video compression format used for video CD (VCD) titles and is
compatible for use on DVD titles since all DVD players contain the hardware required
for MPEG-1 playback. MPEG-1 is commonly used in videos distributed on CD ROM. Its
low bit rate and small file sizes are useful when you must fit multiple hours of video
onto a DVD and do not require the broadcast quality of MPEG-2 encoding. A DVD can
contain a mix of MPEG-2 and MPEG-1 video.
