Adobe Media Encoder format options
When you export using the Adobe Media Encoder, you select a format in the Export Settings dialog box for your
output. The format you select determines which Preset options are available. Select the format best suited for your
output goal. In Adobe Premiere Pro, format options include:
A set of standards defined by the Motion Picture Experts Group (MPEG) designed to
MPEG1 (Windows only)
deliver video and associated audio at bit rates around 1.5 Mbps. Generally, MPEG1 movies are suitable for delivery
formats such as CD-ROM and as progressively downloadable files on the web.
A variant of the MPEG-1 standard designed for Video Compact Disc (VCD). VCD is
MPEG1-VCD (Windows only)
a cheaper, more accessible but lower quality alternative to DVD. VCDs use standard recordable CD media, and can
be played in a standard CD-ROM drive. The format provides an image quality comparable to VHS video.
One of a set of standards defined by the Motion Picture Experts Group (MPEG) for delivering video and
MPEG2
associated audio at bit rates up to around 15 MBps. MPEG-2 can deliver high-quality, full-screen, full-motion video.

menus and other features.
