About Captivator Pro and Captivator ProTV
Captivator Pro is a 16-bit ISA video-in-a-window and capture
card which, when connected to a graphics card that supports the
VESA Media Channel (VM-Channel), provides:
• Scaleable full motion video-in-a-window from Composite
and S-Video input in NTSC, PAL, or SECAM format. The
video window can be displa yed on top of other active
windows and mirrored horizontally.
• Capture of video clips when used with a Video for Windows
™
capture application.
• Still image capture from live input using TV Snap.
Captivator Pr o is available with a TV tuner, as Captivator ProTV,

About the Captivator Pro/TV software
The Captivator Pro/TV software, which you use with
Captivator Pro and Captivator ProTV, includes a Setup program
that installs the following program items in the VideoLogic
VM-Channel Options program group:
• Video Control Panel—which you use to configure Captivator
Pro/TV for your input and to adjust the video picture.
• TV Snap—which you use to capture still images from live
input.
• Video Window—a resizeable floating video window which
can be displayed on top of other active windows.
• A ReadMe file , in text fo rmat, that contains information that
was not available when this guide was written.
• Help—online Help files which explain in detail how to use
the Captivator Pr o/TV Video Control Panel, TV Snap, and the
MCI commands that the VideoLogic Captivator Pro/TV driver
supports.
The VideoLogic Captivator Pro/TV driver, which controls
Captivator Pro/TV, supports Microsoft’s MCI video overlay
command set. This command set allows programmers to control
Captivator Pro/TV using applications developed with
programming languages or multimedia tools. The VideoLogic
Captivator Pro/TV driver also allows you to configure your
hardwar e without rerunning the Captiva tor Pro/TV Setup
program.
Introduction
8 Captivator Pro & Captivator ProTV User Guide
System requirements
Hardware
To run Captivator Pro/TV, you need a computer with a
33 MHz 386 SX processor or better, 4 MB of RAM, and a spare
16-bit ISA bus slot. You must have a graphics card with a
VM-Channel connector, such as VideoLog ic’s 928Movie or
PCI Movie, installed in your computer.
To capture video clips we recommend tha t you use a PC with a
66 MHz 486 processor or better and a VL bus 928Movie or
PCI Movie graphics card .
If you have a Captivator ProTV and intend to use the TV tuner, it
is worth supplying a good strong signal—70dB µV for best
results. If the picture is weak and snowy, you may need a better
aerial/antenna or a booster. If you use a booster do not place it
too close to your computer. Your local aerial/antenna specialist
will be able to advise you on the optimum position for your
booster. If you need to shar e an aerial/antenna feed with a TV or
VCR, it is best to use a booster with two or more outputs. If you
use a splitter, make sure it is a low loss type as cheap passive
splitters usually lose too much signal.
Software
To use Captiva tor Pro/TV you need Windows 3.1 or above
running in enhanced mode. Microsoft recommend DOS 5.0 or
above for Video for Windows. If you are using a 928Movie y ou
need version 1.1.1 or above of the 928Movie softwar e. If you are
using PCI Movie we recommend version 1.1 or above of the PCI
Movie software.
To capture video clips you need Video for Windows 1.1 and a
Video for Windows capture application.
To use T V Sn ap you need Video for Windows 1.1.
If you are capturing video clips to your hard disk, do not use
DoubleSpace, Stacker
™
or any similar disk-doubling application,
to compress the data on your hard disk. We also recommend that
you defragment your disk regularly using the Defrag command if
you are using DOS 6.0 or later, or an application such as
SpeedDisk
™
from the Norton Utilities.

Changing Captivator Pro/TV’s hardware settings
This section explains how to reconfigure Captivator Pro/TV’s
base address and interrupt settings. Read this section if your
computer does not boot, Windows does not start, the
Captivator Pro/TV software is behaving in an unpredictable way,
or if you have installed another card which appears to conflict
with your Captivator Pro/TV.
Base address and interrupt clashes ar e t wo of the most common
problems that occur when installing cards. The symptoms for
each vary from one system to another, but typically:
• If you have just installed Ca ptivator Pro/TV and your
machine will not boot or run Windows, you probably hav e a
base address clash.
• If you have just installed the Captivator Pro/TV software and
card and your Captivator Pro/TV applications freeze or quit
unexpectedly, or if you cannot capture video clips, you
probably have an interrupt clash.
How to change Captivator Pro/TV’s base address or interrupt setting
You can c hange Captivator Pro/TV’s hardware settings using the
Captivator Pro/TV Configuration dialog box, which can be r un
directly from the Windows Control Panel. The following steps
explain how to change Captivator Pro/TV’s base address or
interrupt setting.
To pr event data-loss, w e recommend that you quit any other
applications before changing base address or interrupt settings.
Changing Captivator Pro/TV’s hardware settings

The Drivers dialog box appears .
2. In the Installed Drivers list, select [MCI] VideoLogic
Captivator Pro/TV 1.0.
3. Choose the Setup button.
The Captivator Pro/TV Setup dialog box appears.
This dialog box shows the current base address and interrupt
settings.
You can scan your system to find out which base addresses
and interrupts are available. Some of the options shown in the
Captivator Pro/TV Setup dialog box may be grayed out.
If you already know a free base address or interrupt, ignore
steps 4 and 5.
Contents 21Changing Captivator Pro/TV’s hardware settings
4. Click the Suggest button.
The Captivator Pro/TV Address Scan dialog b ox appears.
This dialog box allows you to exclude base addresses from
the scanning process by unchecking the corresponding check
box.
If you know that a particular base address is being used by
another device, u nchec k the box for that address. Scanning a
base address that is in use by another card can cause your
system to lock up. Such conflicts are rare and although
inconvenient they do not do any harm. Once a conflict has
occurred the Captivator Pro/TV software automatically
excludes this base address from futur e scans, thus preventing
the same problem recurring. If you want to scan all the base
addresses including those that have been automatically
excluded, c hoose the Reset button first.
If you are only interested in scanning for free interrupts, you
should exclude all base ad dresses from the scan by
unchec king all the boxes.
If your system locks up, re-boot your computer by switching it
off, and then on again.
5. Choose the Scan button.
22 Captivator Pro & Captivator ProTV User Guide
Setup displays details of any device that occupies each of the
base addresses scanned, and chooses a base address and
interrupt setting that is suitable for your Captivator Pro/TV.
Although very reliable, the Scan option is not 100% accurate
as the configuration of your computer is not designed to be
read using software. This is particularly true of interrupts tha t
are used by d evice drivers that run under Windows—these
interrupts are only used intermittently, and so are very
difficult to detect.
6. Accept the setting or choose another base address or interrupt
from the available options, then choose OK.
If you have changed the original interrupt setting, restart
Windows so that your change can take effect.
If you have changed the base address, follow step 7 below.
7. Exit Windows. Switch off your computer, monitor, and any
hardware devices such as printers connected to your
computer. Leave the powe r cable connected to the power
outlet so that your computer is grounded.
Warning: Always s witch off your computer before removing the
cover and observe the warnings specified in the manufacturer ’s
documentation.
Remove the computer’s cover. Refer to the documentation
supplied with your computer if you are not sure how to do
this. Discharge any electrostatic charge that may have built up
on you or your clothes by touching the metal frame of your
computer—see Handling Captivator Pro/TV on page 10.
Reposition the jumper as necessary. The base address settings
are printed on the card. If you have to take the card out of its
expansion slot to reposition the jumper, carefully disconnect
the VM-Channel cable from Captivator Pro/TV. When you
have repositioned the jumper, reinstall your card following
the instructions on pages 15–18.

Capturing Video for Windows clips
The Captivator Pro/TV softwar e includes a Video for Windows
capture dr iver which can be used with a Video for Windows
capture application, such as VidCap
™
, to record AVI movies. Fo r
information on how to capture video clips refer to the
documentation supplied with y our Video for Windows
application.
Capturing full screen and full motion video
The Captivator Pro/TV Video for Windows capture driver
captures data in raw RGB format corresponding to the number of
colors used by your display mode—256 colors (8 bits per pixel),
65 thousand colors (16 bits per pixel), or 16 million colors (24
bits per pixel). The bit depth that you use determines the size and
frame rate of the AVI clip that you can capture without dropping
frames—the greater the bit depth, the smaller the image must be
and the lower the frame r ate.
Typically, a 486 66 MHz PC with a VL bus 928Movie should be
able to capture 320 x 240 16-bit images at 15 frames per second
to disk. (See Capture performance on page 30.)
It is not possible to capture full screen video at full frame rate
because your hard disk would quickly fill up. For example, an
8-bit 640 x 480 video clip, without audio, captured at 30 frames
per second generates more than 9 MB of data per second.
Therefore, when you capture video clips, you must decide
whether the size of the image or the frame rate at which you
want to play the clip is mor e important. If you are capturing a
clip which has little movement, such as a talking head, you do
not necessarily need a high frame ra te. However, a clip with a lot
of movement, will look better if it is recorded at a high frame
rate.
30 Captivator Pro & Captivator ProTV User Guide
If you need to capture full screen video to get the best quality
image, you should use a step capture method—capturing one
frame at a time—and then compress each frame separately
before playback. This will produce a full screen video clip at a
low frame rate. See the documentation supplied with your Video
for Windows capture application for further details on
compressing video clips.
If you requir e full motion video, however, you should use the
Captivator Pro/TV capture driver to capture live video at a
smaller size—such as 160 x 120—at full frame rate, and then use
the acceleration and SmoothScale features on VideoLogic’s
928Movie or PCI Movie to play the clip at full screen and frame
rate.
Capture performance
The quality of the video clips you capture is dependent on the
type of graphics card you are using and the maximum data rate
of your computer. The faster the graphics card bus, the quicker
the data can be passed across it, and the better the quality of the
movie that you can capture. Therefore to capture the best quality
movies, you should use a PCI Movie or VL bus 928Movie
graphics card in a 486 66 MHz or faster PC with a minimum of
8 MB of RAM.
Managing your hard disk
Do not use DoubleSpace, or a similar application, to compress
video data on your hard disk. DoubleSpace uses a considerable
amount of processor time to compress and decompress the data.
This results in a significant drop in the data rate that your PC can
maintain. If the data rate is low, your application will hav e to
drop frames as it is recording to keep up with the video source,
or you will have to record the clip at a smaller size or lower
frame rate.
We recommend that you defragment your hard disk bef ore you
capture video clips, and a t regular intervals afterwards, using the
Defrag command if you are running DOS 6.0 or la ter, or a disk
defragmenter such as Speed Disk from the Norton Utilities.
Defragmenting your disk improves the data rate of your
computer.
Contents 31Capturing Video for Windows clips
Mixing video and graphics
The video information that is passed across the VM-Channel is
mixed with the graphics and then displayed on your monitor.
Therefore what you see on your monitor is what is captured in
the movie. For example, the video clips you capture are recorde d
with the same amount of colors as the display mode you are
using; if you have a clock on top of the video window when you
capture an AVI clip, the overlapping por tion of the clock is also
captured as part of the video.
Preview mode
Preview mode—when an application captures a video image and
displays it on the scr een—is not available in Video for Window s
applications, such as VidCap. Always use Overlay mode.

Snapping video stills
TV Snap is a simple a pplication that allows you to snap still
images from live video and TV input, w hich can be edited and
included in multimedia presentations or publications. Still
images up to 640 x 480 can be snapped in 24-bit, 16-bit or 8-bit
format and saved to a variety of file formats—see page 38.
The video is displayed in the same number of colors as your
display mode. Therefore, you must use a display mode which
uses the same number of colors (or more colors) than you need
in the image you are snapping. For example, if you want to snap
an image with 65 thousand colors (16-bit), you must use a
display mode with 65 thousand or 16 million (24-bit) colors.
This section briefly explains how to use TV Snap to snap and
save an 8-bit 320 x 240 BMP image from a live source, and how
to save part of the captured image using the marquee tool. For
detailed inform ation on TV Snap, refer to the online Help.
If you have a Captivator Pr oTV and are using a TV input, you
will need to refer to Tuning in TV Channels on page 39.
Note: Settings that you make in the Captivator Pro/TV Video
Control Panel are also set in the Video Source and Video Display
dialog boxes in TV Snap.

Problem Live video is displayed in color, but captured clip/still is in black
and white.
Condition The Video fo rmat is set to 8-bit Palettized and a palette has not
been set for the clip/still. The Windows grayscale palette is used
by default.
Solution Set a palette for your clip/still. See the documentation supplied
with your capture application for details on how to set a palette.
Problem A large number of frames are dropped when capturing video
clips.
Condition The data rate required to capture the video clip is too high for
your system.
Solution Optimize your computer for streamed video capture as follows:
i. defragment your hard disk.
ii. make sure that the capture file, if required, is large enough for
the clip you are capturing.
iii. remove any disk caching pro grams, such as SmartDrive, if
you are capturing to hard disk.
iv. remove any disk-doubling software, such as Stacker and
DoubleSpace, if capturing to hard disk.
v. maximize the amount of conventional DOS memory by
removing any unused TSR programs or device drivers from
your AUTOEXEC.BAT or CONFIG.SYS files.
vi. capture the clip to memory if it is short enough.
If the number of frames dropped is still unacceptably high,
reduce the data ra te of the clip by changing the image quality.
Try one or more of the following:
i. reduce the size of the image you want to capture; for example
capture the image at 160 x 120 instead of 320 x 240.
ii. reduce the audio quality if you are capturing audio. You can
reduce the sample rate (usually 44, 22, or 11 kHz), number of
channels (stereo or mono), or bits per sample (usually 16-bit
or 8-bit).
iii. reduce the number of colors in the ima ge; f or example
capture the image in 65 thousand colors instead of 16 million.
46 Captivator Pro & Captivator ProTV User Guide
Problem Video clip was recorded without dropping many frames, but does
not play back smoothly.
Condition The data rate of the clip is too high for your system.
Solution Compress the video clip using a software compressor—such as
Indeo
™
, or Cinepak™—in V idEdit™ or a similar application.
Problem Quality of the captured clip is poor.
Condition Capture format is set to 8-bit (256 colors).
Solution To capture the best quality clips, set the capture fo rmat to 24-bit
(16 million colors). If this makes the capture files too big, or
causes too many frames to be dropped because of the increased
data rate, set the capture format to 16-bit (65 thousand colors).
This format offers a good compromise between color quality and
the size of your captured clips.
Condition You are using 8-bit video and palette is unsuitable for the clip.
Solution M ake sure that you use a palette which contains the same range
of colors as the video clip you want to capture. See the
documentation supplied with your capture application for details
on how to set a palette f or a clip.
Problem Captur ed clips/stills have Windows graphics in them.
Condition A nything within the boundaries of the video window is captured
when you capture a clip or snap a still.
Solution M ake sure that no other windows or dialog boxes overlap the
video window during capture.
Problem ‘Not enough memory’ or ‘Out of memory’ error message in
Video for Windows application.
Condition Not enough DOS or Windows memory available.
Solution Try one or more of the following:
i. Close all Windows applications apart from the capturing
application, and all clips or snapped image windows within
the capture application.
ii. Exit Windows and restart your computer.
iii. Increase the amount of DOS memory by removing TSR
programs or device drivers from your AUTOEXEC.BAT or
CONFIG.SYS files.

(62575). This cable is suitable for 928Movie with audio, which
uses an ELCO 60 8283 3048 45 001 connector, or a Sound
Blaster
™
, which use Molex 70066-G or 70400-G connectors. You
can order this cable from your Captivator ProTV supplier.
If your sound card does not use the same connectors as a
928Movie with audio or a Sound Blaster, you should be able to
get your local computer supplier to make up a cable, using the
details of Captivator ProTV’s audio output connector given
below and the details of your sound card’s CD-in connector.
When making up a cable we recommend that you protect against
noise by using screened, twisted pair cable.
Captivator ProTV uses a Molex connector, par t number 70543.
The pin outs for this connector are as follows:
