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. http://www.dps.com/ The Truevision Targa 2000 video capture card. http://www.truevision.com/ 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.

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. Return to Top

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. Return to Top

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.

How to get Microsoft ActiveMovie 1.0

ActiveMovie is Microsoft's successor to Video for Windows. ActiveMovie 1.0 is shipped with OEM Service Release 2 of Windows 95. ActiveMovie 1.0 is also bundled with Microsoft Internet Explorer for Windows 95 and Windows NT 4.0. ActiveMovie 1.0 is available for Windows 95 and Windows NT. ActiveMovie 1.0 plays AVI, QuickTime, and MPEG files. IF YOU DON'T HAVE OEM SERVICE RELEASE 2 of 95! ActiveMovie 1.0 is incorporated in Internet Explorer. A full install of Internet Explorer can be downloaded from Microsoft's Web site. Microsoft also provides a free download of just ActiveMovie 1.0. Both can be downloaded from the Microsoft Internet Explorer Web site as described below: http://www.microsoft.com/ie/ Click on Internet Explorer for 95 and NT 4.0 link to get to the download area. There is a pulldown list of products. (6/6/97). Select "Active Movie 1.0 for Windows 95 and NT 4.0" to get just ActiveMovie 1.0 Click the "Next" button. This brings up a page to select the language from another pulldown list. Pick your language (e.g. U.S. English). Click the "Next" button. This brings up a list of links to download sites for amov4ie.exe Dowload this executable and run. It installs Active Movie 1.0 Return to Top

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. Return to Top

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. Select Video | Convert Frame Rate ... in VidEdit For more on video editors, see Video Editors Return to Top

How to crop an AVI file

Microsoft VidEdit 1.1 can crop an AVI file, that is create another AVI file with a rectangular region of the original AVI file: Select Video | Crop ... in VidEdit Undoubtedly, many other AVI video editors can crop AVI files. Microsoft VidEdit 1.1 has the special virtue of being free and available on the Web. For more on video editors, see Video Editors Return to Top

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: ATI Web Page 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 Conversion Return to Top

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. Links to video chip and video card makers follow:

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.
