Digital Video Formats for the Web
Digital Video Playback on other Platforms and Players:
Conversion to AVI, QuickTime, and 4:1:1 MJPEG Movies
The MAEstro Software Movie Conversion Tools are utilities that convert
movies from the Parallax MovieTool JPEG movie file format to Apple's QuickTime
or Microsoft's AVI movie formats. QuickTime and AVI are de facto
movie standards and are widely used for distributing movie content on
the World Wide Web. The Movie Conversion Tools allow owners of
Parallax products to make high-quality movies and distribute them to a
large installed base of Macintosh and PC clients.
Parallax's JPEG encoding technology uses a high-quality version of the
JPEG standard called "4:2:2 YUV-encoded JPEG."
However, even though 4:2:2 is perfectly JPEG-compliant, not all
hardware and software JPEG decoders can deal with 4:2:2 JPEG images,
but can only handle the lower-quality 4:1:1 JPEG,
making interoperability a problem.
To solve this problem, the MAEstro Software Movie
Conversion Tools also include a feature that converts 4:2:2 JPEG
movies into 4:1:1 JPEG movies, making movies accessible to a wider
variety of movie players on all platforms.
The Movie Conversion Tools also includes an Image Conversion tool that
converts Parallax-captured 4:2:2 JPEG still images into 4:1:1 JPEG
