Buz Capture Card Installation






January 1999 


Buz Multimedia Producer is a technologically sophisticated package. Ensure your system has the latest video and audio drivers installed. It is recommended that you optimize your hard drive using the Windows 95/98 system tools such as Scan Disk and Disk Defragmenter. Before installation, disable all system crash recovery, anti-virus software, or other background-running software. For additional troubleshooting information, see Iomega’s web site: www.iomega.com.

The Iomega BUZ software MUST be installed before the Iomega BUZ hardware! BUZ will not function correctly if you do not load your software first!

  1. Install the BUZ software: Start your computer. From the Windows 95/98 main screen, insert the CD marked "Start Here (Disk 1)’ in the CD-ROM drive. Follow the instructions on the screen. If the install program does not start, double-click on the CD-ROM icon then double-click the START icon and follow the instructions on the screen.
    1. Select Software/Hardware Install
    2. Accept the License Agreement
    3. Select Full Installation
    4. Select the Destination (C:\Program Files)
    5. Start Copying Files
    6. Select Tower/Desktop Installation Tutorial

The default install settings will automatically install the software and drivers. When the software is completely installed and you have watched the Buz Multimedia Producer Installation Tutorial, proceed to the next step.

  1. Shut down and turn off your computer. Disconnect the power cord and remove the computer cover.
  2. Locate vacant slot: Locate any vacant PCI expansion slot and remove the expansion slot screw and cover. Save the screw for step #5 below.
  3. Unpack the Buz card: Caution. Touch a grounded metal object to discharge any build-up of static electricity before handling the Buz card. Handle the card by its edges. If you lay it down, place it on the static-proof bag it is shipped in.
  4. Install the Buz card: Push the Buz card FIRMLY into the PCI slot and replace the PCI slot cover screw. Caution. Do not connect a SCSI boot drive or SCSI CD-ROM drive to the Buz card until after you have installed the Buz software.
  5. Replace computer cover: Replace the screws that hold the cover in place. Do not plug your computer in or start your computer yet!
  6. Connect the Buz cable to the back of your computer. The Buz cable connects to the 15-pin connector. The longer connector is the connector for external SCSI devices. Check orientation before connecting. After connecting, gently tighten the thumbscrews.
  7. Audio In: The smaller of the two Buz box connectors is the Audi In connector. Plug this connector into either ‘Audio In’ or ‘Microphone" on the computer sound card.

    Audio Out: The larger of the two Buz audio connectors if the Audio Out Passthrough connector and goes on the back of your computer. Plug the Buz Audio Output "Passthrough" connector into the ‘Speaker’ or ‘Audio Out’ of the computer sound card.

  8. Reconnect the power to the back of your computer and start your system.
    a. After you restart your computer, Windows 95/98 will display the message: ‘Found New Hardware: PCI SCSI adapter’, and then will identify it as Iomega Buz: PCI Ultra SCSI Host Adapter and will automatically load the drivers. You may need the Windows 95/98 Installation CD for the selected drivers.
  9. b. It will then identify a PCI Multimedia Video Device and identify it as Iomega Buz Multimedia Producer and will automatically load drivers for this also. You will then be prompted to restart the computer. Click Yes.

  10. After the computer reboots, The Buz Display Diagnostic menu will be displayed. You should see a black and white rectangular image in all four corners of the display screen. ). Follow the screen prompts.
  11. Connect the video input and output devices into the Buz box. VCR, camcorder, or other video source to your BUZ box (can be performed now or later).
    Caution. Do not connect your audio equipment to the composite video input or output jack. You could damage your equipment of your Buz card.
    Caution. Do not connect Composite and S-Video inputs at the same time. Use one or the other. 

In order for the Iomega BUZ Multi-Media Device to work properly with the APAS, you must download and install the Buz Drive Update file from the Iomega web site (www.iomega.com). The steps for installing the updated drivers are listed below.

Hi Normand Teasdale!

You are experiencing a video codec problem on your computer. A codec is small software or hardware that decompress the video to a format that the program can understand. This codec is not installed on the computer.

I guess that you dont intent to buy another Iomega Buz capture board wich could solve the problem also, so the solution will be to install a software codec. We currently use the Morgan MJPG codec wich is working OK with the APAS system. Visit the Morgan web site and download the codec. Follow the instructions how to install it.

Here is the link to the Morgan-Multimedia Web site:

After the installation and a reboot the APAS should be working. If you encounter more problems just let me know.

I have a couple of suggestions for you to try with Stream Capture on your
new system.

1) Try defragmenting the drive that contains the temporary capture file.

2) specify a different drive for your temporary capture file. Also
defragment that drive if you are having problems

3) Try to find some setting that works. For example try reducing the image
size from 720x480 to the next smaller size. Try changing the "Quality" to a
smaller number. Reduce the time of collection. When you find something that
works, work your way up to find settings which break the process and result
in dropped frames.

I have a 166 vanilla Pentium & I can capture full screen ok. Yesterday I
was having a problem which I solved by moving the temporary capture file to
a different drive. The original was almost full which I believe was causing
my problem.

Good luck, Jeremy






A standard video picture is made up of odd and even lines across the screen. Television standards require these lines to be interlaced. This means only half of the lines are displayed in one field. The first (odd) set of lines is displayed in the first field while the second (even) set of lines is displayed in the second field. These two fields comprise a frame, which is a complete picture.

When capturing a video sequence utilizing the full speed provided with today's video standards, it is normally required to use special VCR equipment with field-by-field stepping capabilities. Industry standard hardware and APAS software modules make it possible to capture video sequences from a VCR or camcorder directly to the computer hard drive without special requirement of expensive VCR equipment. Any VCR can be used as a video source with the APAS.

The APAS system uses hardware and software that has Motion JPEG image hardware compression that also complies with the major hardware vendors. After capturing the video to the hard drive, the APAS system allows separation of each frame to its two component fields.

Depending on the hardware and software combinations used for recording and displaying the AVI files, it is possible for the order of the displayed fields to be reversed. It is also possible for the same AVI file to play in normal order on one computer and in reverse order on another computer! For this reason, the Ariel CAPTURE, TRIM and DIGITIZE programs provides the option to specify the order for displaying the images of the AVI files.

If it appears that the images are "jerky" or are being displayed in a "zigzag" manner, the field order probably needs to be reversed. The field order is specified using the following steps.




  1. Select CAPTURE and CAPTURE PARAMETERS. The Algorithm Defaults menu will be displayed. Click on the STREAM tab to display the Streaming Capture options menu. Select either Normal or Reverse order in the MJPEG section. The current selection is indicated by the black dot to the left of the option. NOTE: When this option is changed, it affects all other APAS software modules where the AVI file can be displayed (Capture, Trim, Digitize, Display, Vectors etc.)
  2. Select OK to proceed or CANCEL to abort.




  1. Select OPTIONS and MJPEG. The MJPEG Options menu will be displayed. Left-click either Normal or Reverse order. The current selection is indicated by the black dot to the left of the option. NOTE: When this option is changed, it affects all other APAS software modules where the AVI file can be displayed (Capture, Digitize, Display, Vectors etc.)
  2. Select OK to proceed or CANCEL to abort.




  1. Select FILE, SEQUENCE and NEW (or OLD) and specify the Sequence Name.
  2. Select FILE, NEW (or OLD) VIEW and specify the View File and the corresponding AVI file.
  3. Select IMAGES and VIDEO to display the Video Options menu. Left-click either Normal or Reverse order. The current selection is indicated by the black dot to the left of the option. NOTE: When this option is changed, it affects all other APAS software modules where the AVI file can be displayed (Capture, Trim, Digitize, Display, Vectors etc.)
  4. Select OK to proceed or CANCEL to abort.



The Image Order information is stored in the WIN.INI file. Once this parameter is set in the Capture, Trim, or Digitize module, the Ariel software will remember the current setting. The following information is listed in the WIN.INI file of the APAS computer.

[APAS System Information]



When Reverse Fields is set to 0, the APAS software reads the video fields in normal order. When the Reverse Fields is set to 1, the video fields are displayed in reverse order.


Dear Antonio,
I received you note about your difficulty about using the Panasonic
7350 VCR with your new Ariel APAS system. Does your new system have
the Iomega buz director capture card? I have just installed a card in
my desktop system, in addition to having the traditional APAS system
with the Panasonic 7350 VCR with the shuttle remote and the the p34
or RS232 serial computer control for the VCR used to step the VCR
frame by frame through the videotape.If you new system has the buz
capture card then what you are going to do is use the streaming of
the video and capture the segment that you desire. From your
description this is what is perplexing as you have to view the image
in the little viewer box on the computer which has a delay and then
you have to use the trimmer function to edit the exact segment that
you want to digitize. I am doing it similarly at my home with my HI8
camcorder. In the lab what I have done to make the viewing easier
because of the delay, is to use the BNC connector similar to the
connectors on a Kistler forceplate amplifier and connect an extra
monitor to the video output jack. Your 7350 VCR has RCA outputs,
S video and the BNC jacks in the back of the unit.
You could select any of them for the monitor but you probably want to
save the S video output to go to the Iomega break out box coming from
the capture board, because this output has the best analog resolution
from this great VCR. To utilize the complete resolution available
by this VCR you should have taped the movement using a SVHS recorder
and used SVHS tape. If you don't have a SVHS recorder but have a
Hi8 camcorder than you still need to use SVHS tape when you down
load the format , in order to take adavance of the resolution. Please
take these comments as just general information because I don't have
any idea about your knowledge about videography and sometimes simple
informational items are not communicated or are skipped in a
discussion, as I experience with my students daily. By connecting
this extra monitor or TV in parallel, you are now able to see real
time the video that is being streamed into the buz capture card.
You'll still need to probably trim the video startup and end segments
a little but you'll be very close to the exact segment that you
desire to digitize. This way you can use the shuttle on the 7350 to
easily locate your video segment and then capture it. Remember that
after you find the segment, when you are ready to capture the segment
that the VCR takes a little time to take the slack out of the tape in
the playing heads and then reach the proper tape transport speed for
an accurate time base. 
I hope you find my comments/suggestions helpful and please feel free
to call me at 812-237-3927 (office) or home 812-299-9485 (home) or
The new APAS system works great.
Good Luck,

Hi John & Gideon,

We made the grabber work to day. We changed the image size from 352 x 288
CIF to 720 x 576 FULL in the RealCap program. Then we discovered that the
compression ratio had to be adjusted, otherwise we would loose frames. The
JPEG quality is now set to about 42 kb/frame.

Then I also had to change the order to reverse, but it seems to be reliable
and consistent now.

Are you surprised that 352 x 288 gave identical odd and even field?

Another thing I can't figure out is when we have colors or not on the AVI-file.

Best wishes

Tips For Better Capture


To ensure that you capture the highest quality video you may want to follow these steps. If you system is not optimized, the result may be dropped video frames. Video with dropped frames will look jittery and will have audio dropouts.
1) Run Disk Defragmenter. Creating, modifying and deleting files causes fragmentation of your hard drive.You should defragment your hard disk every month to maintain an optimal disk. Depending upon the size and speed of your hard drive, this process could take up to an hour or more.
a) Close all applications.

b) Click Start.

c) Click Program.

d) Click Accessories.

e) Click System tools.

f) Click Disk Defragmenter.

g) Select the drive you would like to defragmet.

2) Don't run other applications while your are capturing video to your hard disk.

3) Change your "Typical Role" settings from desktop computer to Network Server. This will increase the size of the file and directory cache. This results in increased speed when accessing the hard disk.
a) Right click on "My Computer".

b) Click Properties.

c) Click Performance.

d) Click File System.

e) Click arrow next to "Typical Role of this machine" and select "Network Server".

f) Click and drag the "Read –ahead" optimization slider all the way to full.

g) Click OK.

h) You must restart your machine for these changes to take effect.

4) Be sure that DMA is enabled for IDE hard disks. DMA access has lower CPU overhead and transfers data faster.

Note: Not all hardware supports DMA access. If DMA is not supported by your hardware you will need to restart your PC in safe mode to disable DMA.
a) Right click on "My Computer".

b) Click Properties.

c) Click Device Manager tab.

d) Double click Disk Drives.

e) Double click your hard disk. It will be labeled Generic IDE type XXX.

f) Click the Settings tab.

g) Enable DMA by clicking the mouse in the check off box.

h) Click OK.

i) Click OK.

5) Modify the minimum and maximum memory size for the Windows 98 32 bit disk cache. Windows reserves all memory not in use for disk caching, loading additional applications will cause the disk cache to shrink and enlarge. Manually setting the size of the disk cache can improve efficiency.

Note: RAM allocated to the cache cannot be used by applications.
a) Click on Start\Run. Type in SYSEDIT. Click OK.

b) Click on the SYSTEM.INI window.

c) Search for [vcache] section

d) If you do not have this section add the following lines to system.ini.

e) [vcache]

f) MinFileCache=

g) MaxFileCache=

6) The more RAM you have the higher you should make these settings.
a) If your PC has 32 MB of RAM set min to 2048 (2MB) and the maximum to 4096 (4MB)

b) If your PC has 64MB RAM or more set min to 4096 (4MB) and the maximum to 16384 (16MB)

c) If your PC has 128MB RAM or more set min to 4096 (4MB) and maximum to 32768 (32MB)

7) Close the window and click YES to save your changes.

8) Restart the computer to activate the new settings.
