- Indeo(tm) Video R3.2/QuickTime for Windows 2.0 (or 1.1)
-
- Release V3.22.23.04
-
- 23 September 1994
-
-
-
- Description:
-
- ------------
-
- This QuickTime for Windows component supports Indeo Video Release 3.2 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.
-
- * recognizes when the "Indeo Palette" is used and supports the fast 8-bit
-
- Indeo CLUT color converter.
-
-
-
- This decompressor can play back Indeo Video R3.1 and R3.2 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 Indeo Video Release
-
- R3.1 and R3.2 codecs. 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.
-

-
-
-
- Software Prerequisites:
-
- -----------------------
-
- * Windows 3.1
-
- * QuickTime for Windows 2.0 (or 1.1)
-
-
-
-
-
- Installation Instructions:
-
- --------------------------
-
- Copy the QuickTime for Windows component QTIV32.QTC to the QTW bin directory.
-
- This is normally "\QTW\BIN". If the Indeo R3.1 component (QTIV31.QTC) exists
-
- you may remove it because QTIV32.QTC plays back both R3.1 and R3.2
-
- videos. After copying the file to the QTW bin directory restart WINDOWS.
-
-
-
-
-
- New In This Release
-
- -------------------
-
- 1) The CODE segments were marked as DISCARDABLE to improve overall system
-
- performance.
-
-
-
- 2) 16-bit playback quality was improved for "Hardware" and "Driver"
-
- playback.
-
-
-
- 3) DecompressFlags and FormatFlags in the CodecInfo structure were corrected.
-
-
-
- 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 "3.2.4".
-
-
-
- 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 codes: "IV31", "iv31",
-
- "IV32", and "iv32".
-
-
-
- 4) Videos with odd dimensions (other than multiples of four in height
-
- and/or width) are supported with reduced playback performance.
