            Indeo(tm) Video Raw R1.1/QuickTime for Windows 2.0 (or 1.1)

                           Release  V1.10.23.01

                             23 September 1994



Description:

------------

This QuickTime for Windows component supports Indeo Video RAW videos under

QuickTime for Windows 2.0 (or 1.1).  This component:

* decompresses videos with sizes from 16x16 to 640x480. 

* supports color depths of 8, 16, and 24 

* supports the fast display modes "Hardware" and "Driver" for normal and 

  2x-Zoom playback. 

* supports arbitrarily stretched and odd dimensioned videos using the "RAW" 

  display mode.

 

This decompressor can play back Indeo Video Raw videos converted to ".MOV"

format from ".AVI" format using Intel's SmartCap utility.  It can 

also play back movies created on the Macintosh using the Intel Raw Video 

codec.  Videos created on the Macintosh must be saved as "Single Fork" 

files and "Playable on non Apple computers" before they can be played 

under QuickTime for Windows.



 

Display Modes:

--------------

QuickTime for Windows has three display modes that all decompressors support:

"RAW", "Driver", and "Hardware".  "RAW" is the slowest and most general 

method.  It is used when stretching to odd sizes.  The "Hardware" display

mode is the fastest mode because the decompressor writes directly to the 

"Hardware".  In color depth 16 "Hardware" and "Driver" are supported for

bit packings 5/5/5 and 5/6/5.  They are not supported for either 6/6/4 or 

6/5/5.



QuickTime for Windows allows the user to request a display mode.  It will

use the requested mode if it is supported for the requested action, otherwise, 

it will use the next fastest mode that is supported.  "Hardware" is the 

default display mode.  To request another mode, modify the QTW.INI file.  

Change (or add) the "Optimize" definition in the [Video] section.  In the 

following example "Optimize" is set to "Driver":



    [Video]

    Optimize=Driver



If QuickTime for Windows is having trouble working with your video card

you may want to request that it use the "Driver" output mode.

New In This Release

-------------------

 1)  8-bit playback performance and quality were improved for normal and 

     2x-Zoom "Hardware" and "Driver" playback.

     

 2)  16-bit playback performance and quality were improved for normal and

     2x-Zoom "Hardware" and "Driver" playback. 

     

 3)  This component can decompress movies with odd dimensions (width and/or

     height not a multiple of four).



 4)  The CODE modules were marked as DISCARDABLE to improve overall system

     performance

     



Known Operating Characteristics:

--------------------------------

 1)  The version number returned by GetComponentVersion() uses the same

     format as the QuickTime for Windows version number returned by 

     QTInitialize(): bits 31-16 are zero, bits 15-12 have the major number, 

     bits 11-8 have the minor number, and bits 7-0 have the revision.  

     The unpacked version number for this release is "1.1.1".

     

 2)  Although video can be rendered to 8-bit color, we recommend configuring

     your graphics controller to 16-bit or 24-bit color for improved visual

     clarity.



 3)  Videos are identified by a four-character-code (Four-CC). This 

     decompressor supports the following four-character code: "YVU9".
