QuickTime 3 Sorenson Video Developer Edition
Video compression has always involved a tradeoff
between bandwidth and quality-giving up quality in order
to fit the video stream into the available bandwidth. We
make it easy. With the Sorenson Video QuickTime codec
from Sorenson Vision, you can now produce very high
quality video, even with low bandwidths.
Sorenson Video is a QuickTime 3 video compressor
designed for developers of applications or web sites that
require compressed video segments. The Sorenson Video
system includes a full compressor/decompressor for use
during productions. Decompressors for playback are built
into QuickTime 3.0. The efficiency of the Sorenson
algorithm makes it possible to decode the video stream
without the high-end processors required by other
The Sorenson Video codec is the result of over ten
years research and development and delivers an
unparalleled combination of image compression and image
quality. The Sorenson Video codec uses new vector
quantization techniques, advanced motion compensation,
and precise adaptive rate control features. The result is
a highly compressed, high-quality video stream for use in
multimedia applications, the world-wide-web, or any other
application where a high-quality, low-bandwidth video
stream is required.
The Sorenson Video Compressor Developer Edition is a
QuickTime 3 component. This allows users access to it's
additional benefits under all QuickTime 3 applications.
All content created with the Sorenson Video Developer
