Video Capture Cards with Windows NT Drivers
The DPS (Digital Processing Systems) Perception ISA video capture card.
The DPS PVR-2500 Perception Video Recorder (PCI-bus)
for Intel and DEC Alpha Windows NT workstations. An optional
AD-2500 real time video capture daughter card adds component,
S-Video, and composite video inputs to this high-end product.
The AD-2500 is the actual capture card in this product which is
a "digital video disk recorder system".
The DPS HVR-2800 Hollywood Video Recorder (PCI and ISA). The PCI
version is available for both Intel and DEC Alpha Windows NT
workstations. The Hollywood is also a "digital video disk
recorder system", more than a simple video capture card.
DPS makes PC video products aimed at the studio and broadcast
production markets.

The Osprey 100 PCI Video Capture Card works under Windows NT as well
as Windows 95. The Osprey Systems Division of Multimedia Access
Corporation makes a line of video capture cards, all or some with
drivers for Windows NT 3.51 and NT 4.0
The Osprey 100 is a PCI board based on the BrookTree Bt848 single-chip
video capture device. The version of the Osprey 100 that I have seen
has one S-Video input and two composite (NTSC or PAL) video inputs.
The Osprey 100 has software and drivers for both Windows NT 3.51 and
Windows NT 4.0
The NT software for the Osprey 100 (10/8/97) consists of the VidCap32
video capture application, a Video for Windows Capture Driver, and
a Windows NT Device Driver for the Osprey. There are at least
two versions of the software: 0.93(beta) and 0.95(beta). On
10/7/97, the 0.95(beta) was available by anonymous ftp from
Osprey.
The anonymous ftp site also contained directories for a 1.00 version
of the software that could not be downloaded (10/7/97).
The 0.95(beta) software from Osprey is a single Windows executable
that easily installs VidCap32 and the drivers, also updating the
NT taskbar, registry, and so forth.
The Osprey 100 with the 0.95(beta) drivers captures video under NT 4.0
with both VidCap32 and the Progressive Networks RealEncoder software.
At least in some of my experiments, VidCap32 exhibited some problems
although it was possible to repeatedly capture AVI clips. Problems
included flawed updating of the VidCap32 window and sluggish
performance of the NT system until rebooted. The problems appeared
intermittent.
System Tested:
(Micron Millenium PC) Intel Pentium 132 MHz with 48 MB RAM
Phoenix BIOS Version 4.04 M-M
Windows NT 4.0 (Build: 1381 Service Pack 2)

How to Create AVI Files from Television
To create an AVI file from your favorite television program, there
are two approaches.
Television is transmitted over radio frequency (RF) waves.
The NTSC, PAL, or SECAM composite analog television signals
are modulated onto high frequency radio waves to create the
familiar television channels. In the United States, television
channels 2 through 69 cover the range from 54 MHz to
806 MHz. An NTSC channel uses about 4 MHz of frequency
range.
Traditional analog Cable Television (CATV) works much the
same except that the RF is sent over coaxial cables instead of
the open air.
A device usually referred to as a tuner can demodulate the
television radio frequency signal and extract the NTSC, PAL, or
SECAM composite analog signal. Television sets, Video
Casette Recorders (VCR) and cable television set top boxes contain a tuner.
The easy way to turn your favorite television show into an
AVI is to record the show to a videotape using a VCR. The VCR
can output the composite analog video signal to a video
capture card in your PC (see the section on creating AVI from
composite analog video).
A number of companies market TV tuner cards for PC's. In this
case you can feed the television radio frequency (RF) signal
into the TV tuner card which will demodulate the NTSC, PAL, or
SECAM signal. Use an associated video capture card to convert
the demodulated composite analog video to an AVI files.
ATI Technologies, for example, markets a PC TV Tuner.
It is probably simpler to use a VCR than a PC TV Tuner card.
A VCR circumvents the often painful installation problems
with PC hardware.

How to Create Morph Effects for AVI
Morphing is a technique for progressively transforming one image
into another image, or one video sequence into another.
For example, a video producer might morph one face into another.
STOIK Software markets a tool called
Morph Man for Windows 95
http://www.stoik.com/
Morph Man can create AVI files with a still image morphing into
another still image, or one video sequence morphing into another.
STOIK provides a demonstration version of Morph Man for
evaluation purposes.

Reinstalling Microsoft's Video for Windows in Windows 95
This requires the Windows 95 CD-ROM. One can either reinstall
Windows 95 (probably not what you want to do) or manually remove
Video for Windows and manually reinstall the files that make up
Video for Windows under Windows 95.
Truevision's Technical Support has a good note on how to do this.
Although it does not appear to be copyrighted, I felt uncomfortable
cutting and pasting it into the AVI Overview. The URL is

Installing and Configuring AVI Codecs in NT 4.0
The Microsoft Windows NT 4.0 applications and operating systems
are configured through the NT Registry, which is similar to the
Windows 95 Registry. Although Windows NT 4.0 and Windows 95 share
a desktop user interface, there are some significant differences
between the NT 4.0 Registry and the Windows 95 Registry.
In NT 4.0, the 32 bit video codecs do not appear to be listed
in a [drivers32] section in the SYTEM.INI file. This differs from
Windows 95. The Video for Windows configuration information appears
to be stored almost exclusively in the NT Registry in NT 4.0.
The NT Registry can be viewed and modified through the Control
Panel or through the REGEDT32 Registry Editor. Use the Control
Panel unless you really know what you are doing.
You can view and change which audio and video codecs are installed
through the Multimedia icon in the Windows NT 4.0 Control Panel (in My
Computer). This works much the same as the Multimedia icon in the
Windows 95 Control Panel (in My Computer).
Double click on the Multimedia icon to launch the Multimedia applet.
Select the Devices tab within the Multimedia applet. This tab gives a
list of installed multimedia drivers including hardware device
drivers, MCI drivers, and audio and video codecs. It includes two
sections:
(cute icon)Video Compression Codecs
(cute icon)Audio Compression Codecs
Double-click on these to view the installed audio and video codecs.
There are buttons to Add.. or Remove... multimedia devices
including the audio and video codecs.
To Add a video codec, click the Add... button. This gives an Add
dialog box with a List of Drivers. You may select from a list of
drivers that the system knows about, such as "Cinepak", or select
"Unlisted or Updated Driver". If you need to use "Unlisted or Updated
Driver" you will need a directory on a floppy disk, CD-ROM, or your
hard drive containing the needed drivers and an INF (Setup Information
) file. Depending on what you are doing, the needed directory may be
on a floppy provided with a product, on the Windows NT installation
CD-ROM, or constructed manually by you or someone else. The INF file
provides directives for installing the driver including changes to the
Registry. Windows read the INF file and follows the directives.
You may need a different (NT specific) INF file to install under
Windows NT 4.0 than Windows 95.
The 32 bit video codecs are installed in the \WINNT\SYSTEM32
directory used for 32 bit drivers, analogous to the \WINDOWS\SYSTEM
directory in Windows 3.x
NOTE: Using the Remove... button to remove a codec does not
remove the codec files from the hard drive. Nor does the
codec disappear from the list of codecs displayed when
Add... is selected. Remove... appears to simply disable
the video codec so that it is not invoked. Use Add... to
enable the codec after Remove...
The other option to install a codec is to use an installation
program that will appropriately update the NT Registry and copy
the needed files to the correct directories in the NT file
system (such as \WINNT\SYSTEM32). In many cases, you can get
an install program from a Web site or other convenient source.
In this case, you do not need to use the NT Control Panel. The
install program does all of the work.
NT 4.0 appears to be able to use the same 32 bit video codecs as
Windows 95, for example Cinepak for Windows 32. Keep in mind that
device drivers for hardware are different between Windows 95 (which
uses VxD's) and NT 4.0. Only some parts of Windows 95 and NT 4.0 can
use the same code.

How to change frame rate of AVI files
You may want to change the frame rate of an AVI. For example, you
may want to convert a video captured at 30 frames per second (NTSC)
to 15 or 10 frames per second to reduce the size of the file. This
type of conversion throws away frames; it does not play the AVI in
slow motion.
Video editors usually contain this function.
For example, the free VidEdit video editor can convert the frame rate
of AVI files.

Video | Convert Frame Rate ...

How to edit AVI files:
Several applications exist to edit (cut, paste, etc.) AVI files.
Such applications are known as video editors. Sometimes such
digital video editors are called non-linear editors, in contrast to
traditional videotape or film based editing.
Video editors range from very simple applications to very sophisticated
applications.
Video Editor Features
Common video editor features include:
* cut, paste, and deleting video sequences
* selecting video codec and compression settings
* selecting audio codec and compression settings
* converting video frame rate
* converting audio sampling rate
* adjusting synchronization of audio and video
* converting color depth of video (24, 16, or 8 bit usually)
* converting to NTSC or PAL safe colors
* adding transitions and other special effects
* applying image processing filters to video
* adding text and subtitling
* much more in high end video editors....
VidEdit
The full 16 bit (Windows 3.x) Video for Windows from Microsoft (not
the "Run Time") shipped with a simple video editing program VidEdit.
VidEdit can cut, paste, concatenate, add sound, and do many other
things to AVI files. VidEdit can be downloaded from a number of
sites on the Internet.
WARNING: Microsoft's NetShow audio/video/multimedia streaming
product includes a number of new video codecs such as Microsoft MPEG-4 and
VDONet's VDOWave. The NetShow Player installation installs decode
only versions of these codecs, none of which will display in the list
of codecs in VidEdit, sensibly enough. The NetShow Tools install
codecs with encoder capabilities. These will show in the VidEdit
list of codecs. See the section on NetShow for further information.
Some video editors such as Asymmetrix Digital Video Producer (DVP)
4.0 will show the NetShow decode-only video codecs in the list of
codecs for compression, even though these codecs do not compress
video. In fact, if these decode-only codecs are selected to
compress a video clip, the AVI file is not compressed although an AVI
file is generated.
I was quite confused by this behavior until I understood the
distinction between the NetShow codecs with encode enabled and the
decode-only video codecs.
VidEdit does recognize the following 32 bit Video for Windows codecs:
Intel Indeo (R) Video Interactive [32]
Intel Indeo (R) Video R3.2 [32]
Intel Indeo Raw R1.2 [32]
Microsoft Video 1 [32]
Cinepak Codec by Radius [32]
Indeo video 5.0 [32]
VDONet VDOWave [32]
MPEG-4 High Speed Compressor [32]
As far as I can tell Microsoft is not currently distributing VidEdit.
However, a file winvid.zip is bouncing around the Net. This file
includes the Video for Windows run time along with a number of Video Tools
including VidEdit and VidCap (Microsoft's video capture tool).
Disclaimer: I am not certain what the legal restrictions on
VidEdit or winvid.zip are.

How to output an AVI file to videotape:
AVI files generated with a video editor such as Premiere or a 3D
Animation program such as Caligari TrueSpace can be output to
videotape (e.g. a VHS tape) using a hardware device known as a scan
converter. A scan converter converts the VGA signal intended for
the computer monitor into an video signal, typically NTSC or S-Video.
The video signal can then be input into a videotape recorder such as a
VHS VCR.
A scan converter may be a small box which resides between the computer
and the monitor. It may be integrated into a video card. For example, ATI's
new 3D XPRESSION+PC2TV video card includes NTSC and S-Video output as well
as output to a conventional computer monitor.
Configure the PC graphics in one of the modes supported by the scan conversion
hardware and play the AVI file in full screen mode.
Some manufacturers of scan converter (or similar) hardware:

VideoLogic Web Page
PC Video Conversion claims to make a high quality scan converter
called HyperConverter that converts from SuperVGA to broadcast quality
NTSC/PAL video. Less than $5000.

PC Video Chips and Cards
The current (6/21/97) generation of graphics controllers for PC's
incorporate a number of hardware features to improve playback of
video, including AVI. Video acceleration features have become
standard in most chips. As a consequence video chip and card
marketing has increasingly emphasized 3D graphics acceleration
features in an effort to differentiate chips and cards from different
manufacturers. These video acceleration features include hardware
color space conversion and hardware scaling of video.
Color Space Conversion
Many video standards such as Indeo, Cinepak, and MPEG operate in
a luminance - chrominance color space such as YUV, YCbCr, etc. Computer
monitors use RGB (Red/Green/Blue). The decoded video signals must
be converted from YUV to RGB for display. Most video chips now provide
dedicated hardware for this color space conversion.
Hardware Scaling
Displaying a video in a windows larger (or smaller) than the encoded
aspect ratio involves duplication of pixels. Complex filtering
operations can reduce or remove blocking artifacts when a video is
scaled up in size. If scaling is performed in software using the
PC's CPU, the scaling will absorb many CPU cycles, possibly resulting
in degraded video playback depending on the speed of the CPU. Most
video chips now provide dedicated hardware for scaling video.
Video Cards
PC video cards are printed circuit boards. Today (6/23/97), virtually
all video cards are PCI cards, with a PCI bus connector along one side
of the circuit board. The video card will have at least a DB-15
connector for the VGA cable to the computer monitor. Video cards have
a chip variously known as a graphics controller, graphics accelerator,
video chip, video controller, or something similar. The graphic
controller is the heart and the brain of the video card.
The card has one or more memory chips forming the video memory where
the images are stored. The video memory is known as a framebuffer.
Video cards have a RAMDAC (Random Access Memory Digital to Analog
Converter) which convertes the digital image stored in the framebuffer
into an analog signal for the RGB monitor. PC video cards have a ROM
(Read Only Memory) with the VGA BIOS used during the PC boot process.
There is also a clock that provides the timing signals for the entire
board.
Many video cards have a feature connector allowing an
auxiliary card to be added to the main video card. The auxiliary
card adds additional features such as hardware MPEG decoding.
Although AVI should be independent of the video chips and cards used in
a PC, there can sometimes be problems or technical issues specific
to a particular chip. By far the most common PROBLEM is a subtle
bug in a video chip driver or a subtle conflict between a video
chip driver and another driver or piece of software on the PC. Downloading
and installing the latest video driver from the chip or card maker's
Web site is a frequently successful fix for these problems.
ALSO, Windows 3.x and Windows 95 use different Device Drivers than
Windows NT 3.51 or Windows NT 4.0 Windows 3.x and 95 use Device
Drivers known as VxD's for low-level hardware access. NT uses its
own device drivers. If you use a video card or other hardware
on an NT machine, you need to be sure to use the NT drivers!
A number of video card companies such as Diamond Multimedia and
STB that buy or license the controller chips from other companies such
as S3 frequently write video card/chip device drivers with additional
features or better quality than the device drivers provided by the
chip company.

How to compress the audio sound track in AVI Files
AVI files include support for compressed audio although they are
frequently generated with uncompressed PCM audio. The Windows
Multimedia system includes a component called the Audio Compression
Manager (ACM), an audio counterpart to the Video Compression Manager (VCM).
The ACM enables installable audio codecs.
Unfortunately not all authoring applications access the full ACM. For
example, the free VidEdit application from Microsoft, a simple video
editor, only permits selection of various PCM audio encoding. There
is no way to compress the audio in an AVI file through VidEdit,
although the Windows operating system, through the ACM, and the AVI
file format do support audio compression.
Historically, AVI files were frequently authored with video compression,
usually Cinepak, and uncompressed PCM audio. The size of the audio track
could be reduced by using 8 bit mono (one channel) PCM audio at a
11 KHz sample rate as the "audio format". Microsoft VidEdit, for
example, allows this. AVI was used for compressing video on hard disks
and CD-ROM's. Hard disks and CD-ROM's have plenty of room for uncompressed
audio but an uncompressed video quickly exceeds their capacity.
Thus audio compression was not as critical as video compression.
With the advent of the Internet, with typical bandwidth of a few
Kbits/second, audio compression has become more important.

How to make AVI NTSC (or PAL) Safe
AVI files can represent colors that are not supported by the NTSC or
PAL analog video standards. These colors correspond to
synchronization and control signals in the NTSC or PAL video. Such
AVI files cause problems if translated to NTSC or PAL video.
Equilibrium's DeBabelizer Pro for Windows 95 and NT 4.0 reads and
writes about 90 common and not so common image file formats as well
as AVI files. In addition to translating between all of these formats,
DeBabelizer Pro has a number of image processing functions.
DeBabelizer Pro can remove colors from AVI files that are excluded by
NTSC or PAL to create an NTSC or PAL safe AVI file.
Equilibrium has a demonstration version of DeBabelizer Pro on its
Web site. This is a demonstration version. The demonstration version
adds the words Equilibrium (very large words) to all images and video that
it processes.
