-
- Improvements:
- -------------
- This software update is provided to enhance your existing Indeo(TM)
- Video drivers to the latest video technology for compressing, editing
- and playing back video on your Intel microprocessor-based desktop
- computer, using Microsoft's Video for Windows* Version 1.1.
-
- Indeo Video technology gives you the capability to capture and
- compress video in a single step using Intel's Smart Video Recorder,
- as well as, the ability to encode and/or decode (i.e. playback) video
- using only software on your PC.
-
- Intel's Smart Video Recorder product works with camcorders, VCRs and
- laser disks to capture Indeo Video. It immediately compresses NTSC
- or PAL format files at: 320x240 pixel resolution up to 15 frames per
- second (fps), 240x180 up to 24fps, and 160x120 up to 30fps.
-
- In addition, the built-in scalability of Indeo technology
- automatically adjusts the playback frame rate depending on your
- computer's performance capabilities. This allows you to play Indeo
- video files on any Intel Pentium(TM) or Intel486(TM) processor-based
- computer.
-
- This version of the Indeo Video R3.2 driver is an update to Indeo
- Video R3.1 and Video for Windows V1.1. It provides:
-
- * Improved visual quality. There is significantly more foreground
- and background detail for most sequences, particularly at 15 fps
- with data rates of 135KB/sec or higher.
- * Improved video playback performance at low data rates.
- * Improved 16-bit image quality and playback performance.
- * Improved audio playback at low data rates.
- * Compression and decompression of images up to 640x480 size in
- 4-pixel increments. Note: 640x480x10 video with a 240KB/sec transfer
- rate, has been measured to play back at close to 10 frames per second.
- * Improved software encoder performance (2 to 5 sec/frame on a Pentium
- processor system).
- * Faster initialization.
-
- Indeo Video Drivers:
- --------------------
- Indeo(TM) Video R3.2 -- V3.22.01.30 incorporates the new Indeo
- Video R3.2 software codec that produces
- the highest quality video for software
- playback on Intel microprocessor based
- desktop computers.
- [filename: ir32.dll]
-
- Indeo(TM) Video Raw -- V1.10.1.4 incorporates the raw/YVU9
- codec.
- [filename: iyvu9.dll]
-
- Indeo(TM) Video R2.1 -- V2.17.003 incorporates a decompressor only.
- It plays back files created with the older
- R2.1 codec.
- [filename: ir21.dll]
-
- System.ini Entries:
- -------------------
- The Setup program installs the Indeo video drivers along with the
- latest Video for Windows runtime. It places the following entries in
- the system.ini file for the Indeo video drivers:
-
- [drivers]
- VIDC.RT21=ir21.dll
- VIDC.YVU9=iyvu9.dll
- VIDC.IV31=ir32.dll
- VIDC.IV32=ir32.dll
-
- Previously, the recommended system.ini entries looked as follows:
-
- [drivers]
- VIDC.RT21=indeov.drv
- VIDC.YVU9=indeov.drv
- VIDC.IV31=indeov.drv
-
- Indeov.drv was an "umbrella" driver that used a text file called
- indeo.ini to point to the various Indeo video drivers. The indeo.ini
- file had the following entries:
-
- [GLOBAL]
- DRIVERS=IV31,RT21,YVU9
- [IV31]
- DEC=ir30.dll
- [RT21]
- DEC=ir21_r.dll
- [YVU9]
- DEC=ir21_r.dll
-
- Indeov.drv and indeo.ini are no longer used and may be deleted if desired.
- However, older applications, which install the Indeo video drivers, may still
- use indeov.drv and indeo.ini. Since the name of the latest Indeo video driver
- has changed from ir30.dll to ir32.dll, this would prevent IV31 files from
- accessing the latest driver. To avoid this problem, an exact copy of the
- latest ir32.dll file, named ir30.dll, is also installed by this setup program.
- It is hoped the ir30.dll file will not be used. But if another setup program
- should change the system.ini entries to point to indeov.drv, then the correct
- driver will still be accessed through ir30.dll. In the future, this precaution
- should not need to be taken.
-
- Microsoft Setup Utility:
- ------------------------
- The Setup.exe used to install this update is a modified version of the Setup
- utility Microsoft provides to install the Video for Windows runtime. It is
- possible to make further changes to this program. The Microsoft Setup program
- used to come with V3.1 of the Windows SDK. It is now available to registered
- users of Visual C++ by calling Microsoft Product Support.
-
- Software Prerequisites:
- -----------------------
- * Video for Windows V1.1
- * Windows 3.1
-
- Optimum System Requirements:
- ----------------------------
- For the highest image quality and playback, the following system
- requirements are recommended:
-
- * Intel Pentium processor
- * System RAM: 12+ MB
- * PCI local bus graphics controller
- * SCSI hard drive
-
- For best frame rate performance, put the graphics card in 8-bit
- color mode. For best image quality, put the graphics card in
- 24-bit color mode.
-
- Based on the application and the size of the video file, some
- performance tuning of your computer's resources may be required.
-
- Updates:
- --------
- As new Indeo video drivers are released, they will be available on
- CompuServe INTELARCH and Intel's Application Support BBS at
- (916) 356-3600.
-
- This software update to Indeo Video R3.2 is a software codec change
- only. There have been no changes to the Intel Smart Video Recorder Driver.
- If you do not have the latest version of the Intel Smart Video Recorder
- Driver, V2.00.009 it is available on CompuServe* INTELFORUM and on
- Intel BBS, (503) 645-6275. If you would like more information on
- Intel's Smart Video Recorder, call:
-
- U.S. and Canada (800) 538-3373
- Europe +44-793-431155
- Worldwide (503) 629-7354
-
-
- Developers of AVI Editors:
- -------------------------------
- The following recommendation is for developers of AVI file editors.
-
- To avoid unnecessary recompression, it is recommended the IV31 and
- IV32 video formats be treated as the same video format. This speeds
- up editing operations and improves video quality. When a video editor
- saves an edited AVI file, the video formats of the source video frames
- are compared to the video format chosen for the target file.
- Typically, any frames not in the target format are recompressed. If
- a clip contains a mixture of IV31 and IV32 frames, and the output
- format is IV32, it is not necessary to recompress the IV31 frames.
- The Indeo video R3.2 codec will play back both video formats.
-
- Known Operating Characteristics:
- --------------------------------
- 1) This version of Indeo video supports an active or dynamic
- palette. However, a future update to the VfW runtimes from
- Microsoft is needed to use this feature. See item number 10
- below for details on using Indeo video's fixed palette.
-
- 2) The new Indeo Video R3.2 driver can play back AVI files
- compressed using the older R3.0 and R3.1 drivers. However, AVI
- files created by the R3.2 software encoder cannot be played back
- using the Indeo video R3.0 or R3.1 drivers. Microsoft's Media
- Player will report the error "Video not available, cannot find
- 'vids.iv32' decompressor."
-
- 3) The latest R2.1 driver does not display a setup dialog box from
- the Control Panel.
-
- 4) ActionMedia(R) II boards and RT Video boards can not be used
- to provide hardware capture or accelerated playback of Indeo
- Video R3.x files. Intel is considering options to provide
- these hardware drivers; however, there is no specific timeframe
- to announce at this time.
-
- 5) Frames are dropped when capturing 320x240 or 240x180 images
- at frame rates greater than 15 or 24, respectively. With
- the current hardware and software technology, this is the
- maximum frame rate that can be captured with 0 frames dropped.
-
- 6) Using a Smart Video Recorder in systems with disk drives
- that have a transfer rate < 1.4 Mbytes/sec, random dropping
- of frames may occur.
-
- 7) In VidCap, the overlay option is not supported.
-
- 8) If you experience audio playback being out of synch with the
- video, try:
- a. Playing video from Media Player and configure playback
- (select Device/Configure...) to set "skip video frames if
- behind."
- b. Removing any TSRs.
-
- 9) If you have an ATI Mach 32 graphics board you may need to set
- the "Device Bitmaps" to OFF to utilize the correct palette.
-
- 10) On systems using 8-bit graphic displays, a paletted shift may be
- observed in some applications. To improve video performance,
- the Indeo video codec uses a fixed 8-bit palette. One way to
- minimize this color shift, is to capture the palette used by
- the Indeo video codec and apply it to the application that is
- incorporating video by:
- a) Loading an AVI file into media player.
- b) Selecting copy object
- c) Opening PalEdit program and pasting the copied object
- d) Saving the palette
- e) using this .pal file as the color palette in the
- presentation bitmap image.
