*** PC VIDEO: INDEO VIDEO TECHNOLOGY RELEASE 3.0 ***
COMPARISON OF RELEASES 2.11 AND 3.0
The following table compares the key features of Indeo(TM) video
technology releases 2.11 and 3.0.
Indeo(TM) TechnologyIndeo(TM) Technology
Feature Release 2.11 Release - 3.0
Video Input Accepts NTSC (analogAccepts NTSC or PAL
Source video-composite or analog video-composite
S-VHS/Y-C) or S-VHS/Y-C)
Video 160x120 at 30fps, 160x120 at 30fps,
Capture 320x240 at 15fps 240x180 at 15fps,
320x240 at 15fps
Video 320x240x2-15fps* 2x faster than 2.11
Playback 160x120x15-30fps* Supports files created
by earlier releases
* - Based on processor, hard drive, and video card type and speed.
GENERAL NOTES - RELEASE 3.0
The key features of Indeo(TM) Video Technology release 3.0 are:
* Video playback is two times faster than in release 2.11.
* Picture quality and color reproduction are dramatically improved.
* Files created by earlier versions of Indeo Video Technology can be
played back using release 3.0.
* The new compression algorithm lets you control the quality or data
rate of the captured video, giving you more control over the
appearance of the resulting video file.
* There is built in support for PAL video.
* A new video image size, 240x180, is available. You can capture
video in this new size at frame rates of up to 15fps.
KNOWN OPERATING CHARACTERISTICS OF INDEO(TM) VIDEO TECHNOLOGY RELEASE 3.0
The known operating characteristics of Indeo Video Technology release
3.0 are listed below.
* Frames are dropped when capturing 320x240 or 240x180 images at
frame rates greater than 15fps.
* In systems with disk drives that have a transfer rate of less than
1.4 Mbytes/sec, the Intel Smart Video Recorder may randomly drop
frames.
* The current Intel Smart Video Recorder capture driver and software
encoder support only Key Frames. Therefore, regardless of the key
frame interval setting, only key frames will be captured.
* The overlay option in VidCap is not supported.
* If audio playback is out of synch with the video, try:
* playing video from Media Player and configuring playback [select
Device/Configure...] to "skip video frames if behind",
* removing any TSRs (Terminate Stay Resident programs).
* VidEdit does not allow you to create a file with an image
resolution greater than 320x240.
* Data rates less than 300KB may not be achieved with a Quality
setting of 100%. To achieve lower data rates, lower the Quality
setting. A quality setting of 80% offers a good trade-off.
* Data rates of 150KB cannot be achieved. This problem will be
resolved when the "super compressor" becomes available.
* If you have an ATI Mach 32 graphics board you may need to set the
"Device Bitmaps" to OFF to utilize the correct palette.
