MPEG V
IDEO
MPEG is a full-motion video compression technology that
allows you to play back television-quality video. It records
changes between frames of data. Rather than storing
information about each individual frame, only the changed
data is stored during recording and reassembled during
playback.
Fahrenheit ProVideo 64 features the Xing Software
MPEG codec for full-screen, full-motion playback of
MPEG digital video. This codec algorithm attains the
highest playback quality while optimizing file manage-
ment. It also uses high-quality scaling and pixel interpola-
tion algorithms.
The Fahrenheit ProVideo 64 uses your computer's CPU
for MPEG decoding. MPEG playback performance is
directly related to processor speed, the current screen
resolution and color depth. As a reference, a Pentium
90MHz system will usually provide smooth video play-
back at 30 frames per second in resolutions up to
1024x768. Slower systems may provide less perfor-
mance. The MPEG decoding software can be used in all
resolutions except 16 color modes and 1600x1200
resolutions.
Playback of MPEG digital video is enhanced with Fahren-
heit ProVideo 64's SuperZoom feature. With SuperZoom,
video clips captured at small window sizes can be played
back at full-screen full-frame rate. Video clips com-
pressed in .AVI format can take advantage of SuperZoom.
You get smooth video playback without dropping frames
and continuous audio data.
MPEG Video will appear as an option on the device menu
of any Windows MCI (Media Control Device) applica-
tion. MCI is a standard control device for multimedia
devices and files.
NOTE: The Fahrenheit ProVideo 64's MPEG feature is not
compatible with CD titles written exclusively for the
Sigma Designs RealMagic products.
