MakeItMooV -- V1.2

  This application changes the type and creator of a file to "MooV" and
  "TVOD" respectively.  The former allows the file to be recognized as
  a movie file by all QuickTime applications;  the latter causes the
  MoviePlayer to be the default application for opening the file.

  This utility is useful when importing movies from non-Macintosh
  environments (QuickTime for Windows), in which they are not assigned
  appropriate Macintosh file types or creators.

  Double-click on the MakeItMooV icon for further information and usage
  instructions.

Indeo(R) Video CLUTs

Use this document to attach the Indeo Video CLUT (palette) to a MooV file. This
ResEdit document contains two CLUTs. One contains 256 entries for QuickTime
movies that are intended for playback on Macintosh based computers. This process
will improve image quality but may or may not affect playback performance. The
236 entry CLUT is for attaching to movies files intended for playback using
QuickTime for Windows (QTW). Movie files with an attached CLUT will have both
improved image quality and playback performance under QTW. The QTW Indeo video
decompressor can use an optimized dither algorithm if it is dithering into the
Indeo video CLUT. The following tools can be used for attaching the Indeo video
CLUT:

  	* MoviePlayer 2.0, Hold down the Control key while launching the MoviePlayer.
  	A Colors selection will be available from the Get Movie Info menu.
  	
  	* SetMovieColorTable, Open the movie file and then open the Indeo(R) Video
  	CLUTs file and select one of the two CLUTs.
  	
  	* Debabelizer 1.6, Import the ResEdit document by using the
  	Misc/Scripts-Palettes-Etc menu item. After loading these CLUTs, you can use
  	the following:
  		
  		o File Open
  		o Save As... with these settings
  		
  			. Save type: QuickTime Movie: Color Table ONLY to QT MooV
  			. Save # colors: auto set check box
  			. Before save do script: NOTHING
  			. Naming: Original name and No extension radio buttons
  			. Save button check boxes all unchecked
  			
  	A dialog box will be displayed that allows you to choose one of the Indeo
  	video CLUTs.
  	
  
      
Intel Raw Video codec --  V1.10.20.02
-------------------------------------
These notes describe the Intel Raw Video codec, a compressor/decompressor
for YVU9 format video in Apple's QuickTime 1.6.1 and 2.0 video environments.

* YVU9 is the format in which video is captured by the Intel Smart Video
   Recorder. In YVU space, a pixel is represented by one luminance (Y) value
   and two chrominance (U and V) values.  In YVU9 format, the chrominance
   values are sub sampled: a single UV pair is used to represent the
   chrominance of an entire 4x4 block of pixels.  Since Y, U, and V components
   are each stored as 8-bit numbers, the color sub sampling results in an
   average 9 bits per pixel.  Because the human eye is more sensitive to
   luminance than to chrominance, the perceived loss of information due
   to sub sampling is minimal.

* By providing the capability to read near-lossless captured movie files with
   the Intel Smart Video Recorder (that operates under Windows), the Intel Raw
   Video Codec provides a path to compress this higher quality source using
   Indeo Video codec, which performs spatial and temporal compression
   resulting in much smaller files. 

* This codec will appear in compressor selection menus as "Intel Raw".

Major Differences From V1.10.20.00
----------------------------------
There are no functional differences from the previous version of this codec.
The codec has been rebuilt with the an updated release of the compiler and with
the most current QuickTime (2.0) header files.

Known Operating Characteristics
-----------------------------
* The compressor now assigns 24-bit format to the output stream instead
   of 32-bit (for portability to the Video for Windows environment).

* The compressor now appends a version string to the end of the binary data
   for each frame.  To find the version of the compressor used to produce a
   video, search (e.g., with the MPW Shell's 'Search' command) the movie file
   for a string beginning with the characters "Ver ".

* The performance of 16- and 24-bit decompression has been improved.

* Internal change: spooling functions are now handled correctly (although
   data spooling itself is not supported.

* Internal change: the codecGetCompressedImageSize codec function has been
   implemented.


Indeo(R) Video R3.2 codec -- V3.22.24.09
-----------------------------------------

Major Differences From V3.22.21.04
----------------------------------
Native PowerPC support has been added.  Many playback performance improvements
have been put into the 680x0 version of the decoder. The version number has changed
to reflect that this extension now supports PowerMac systems.

The Indeo(R) video codec will only operate on PowerMacs with
QuickTime 2.0 or later. It does not work with QuickTime 1.6.2.

Major Differences From V3.22.21.02
----------------------------------
The decompressor has been optimized, resulting in higher frame rates.

Major Differences From V3.22.21.01
----------------------------------
* Both 'iv32'  and 'IV32' are recognized as Indeo R3.2 movie formats.
   This is for compatibility with some Video for Windows to QuickTime
   translators that produce lower case format signatures.
	
* Memory allocation for large decompressor tables is handled more
   intelligently.

* Playback has been sped up for various depths of gray-level output.

Major Differences From V3.20.21.03
----------------------------------
* The compressor algorithm has been updated from R3.20 to R3.22.
   The new algorithm produces higher quality video with more accurate
   data rate control.  In addition, the maximum size movie that can
   be compressed has been increased from 320x240 to 640x480.

* Decompressor bug fix:  movies whose width was greater than 320 but less
   than 640 could not be decompressed correctly.


Known Operating Characteristics
------------------------------
* Decompressor
  The decompressor is capable of taking advantage of the asynchronous
  decompression features of QuickTime 2.0.

  In addition to any overhead imposed by application software, the
  decompressor requires approximately 148K of system memory (about 128K
  more for 16-bit color, about 256K more for 24-bit color).  Approximately
  248K of application memory are needed for each open 320x240 movie.

  Although error handling is application-dependent, generally
  any movies for which there is not adequate application memory will
  display as blank (all-white) frames until sufficient memory is
  available.  You can make memory available by closing applications,
  closing windows, or closing some of the other movies currently open
  under the same application.  Note that leaving a blank movie open
  may cause the display rate of other movies to be impaired.

  You can increase the number of movies that can be open simultaneously
  by increasing the amount of memory available to the application:
  before launching the application in question, select its icon, then use
  the Finder's "Get Info" command.  NOTE: Problems may occur if application
  partitions are increased to the point that 200K-300K of memory is not
  available for growth of the system heap.

* Compressor
  We suggest you set the key frame interval to 4 when compressing movies.

  Videos compressed with this codec cannot be decompressed by R3.1
  codecs.

  If your application supports data rate constraint by passing a target
  data rate to the codec, the codec will automatically vary the quality
  of the compressed image to achieve the specified data rate.  In this case,
  any user-specified quality information will be ignored.  For example, in
  the ConvertToMovie application, checking the "Limit data rate to..." box
  will cause the spatial quality slider to be ignored;  if the box is left
  unchecked, the spatial quality slider value will be used to determine image
  quality.
  
  NOTE:  MovieShop (an application based on an older codec interface
         paradigm) does not pass data rate parameters to the codec.

* This codec will appear in compressor selection menus as:
   "Intel Indeo(R) Video R3.2."

* We suggest that you SET BOTH THE HEIGHT AND WIDTH OF THE MOVIE TO 
   BE COMPRESSED TO MULTIPLES OF 4.  The Macintosh version of the Indeo codec
   will allow you to compress movies of arbitrary dimensions.  However, if the
   dimensions are not multiples of 4 the playback rate will be affected;  furthermore,
   there is no guarantee that such movies will be portable to other environments
   (e.g., Video for Windows).

* There should be ONE AND ONLY ONE Indeo Video codec in the Extensions folder:
  do not leave older versions there.

MacBinary Conversion Notes:
-------------------------
When this software is distributed on non-Macintosh computers, it must be
first converted into a format that allows Macintosh two fork files to be
read and written as a single fork file. There is a standard for this type of
conversion, MacBinary. The encoding conversion, which takes place on a Mac,
combines the two file forks into one with header information prepended for
later decoding. Files that have been encoded into MacBinary usually have the
'.bin' file extension. After encoding, these files can be transported through
DOS or Unix computers. When they arrive back on a Macintosh computer, they
need to be decoded back into normal two fork Macintosh files. This decoding
can be done by several commercial and shareware applications. The StuffIt
Deluxe and StuffIt Lite versions 3.0.6 (or later) programs can decode
MacBinary files. Use the Translate menu, not File Open, to perform this
decoding. Two other shareware applications that do this decoding are 
available on Compuserve and Internet FTP archives:
