Capturing Video with the JVC-9800 Digital Video Camera
The APAS2000 High Speed System with the High Speed JVC 9800 Camera
Three components are required for capturing 240 Hz video data with the new JVC-9800 digital video camera system:
1. The JVC 9800 Digital Video Camera (supports capture rates of 60, 120 and 240 frames per second).
2. An IEEE 1394 (Firewire or I-link) compliant capture card. Ariel Dynamics recommends the Studio DV by Pinnacle.
3. The APAS software.
1. The JVC 9800 Digital Video Camera
The JVC 9800 DV camera is a consumer type of camera that can be purchased in select video stores or directly through the Internet. Detailed manuals and software are included and provide full explanations of the camera features and functions. This camera is desirable for biomechanics research since it supports capture rates of 60, 120 and 240 Hz. You can check on the prices at http://www.pricewatch.com
2. Digital Capture Card
There are number of digital capture cards available. We at ADI Inc. prefer the Studio DV by Pinnacle. The only problem with this card is that it use a sophisticated proprietary software. The Studio DV software only work with their own card. The cost of this system which include the card and the software is around $125.
The Ulead software is very good and allow the use of almost any digital capture card including the Studio DV.
There is an extensive tutorial that come with this package. However, it is tune for making movies rather then just capturing for Biomechanical use. But it is an adequate method to learn the system very well.
The tutorial to run this system is included here: (Click here) (For the Studio DV by Pinnacle)
Another software that distributed with number of cards in the market is the Eulid software which accompany many of the commercial available cards.
You will need the Adobe Acrobat to read this PDF file, You can download the Acrobat Reader here.
Both of those tutorials are including subjects which are not relevant to capturing video only. They are also including the subjects of making home movies. However, extensive knowledge is learned using these tutorials.
It is also important to note that the Ulead software will
work with the Studio DV capture card. But the Studio DV software will not work
with any other card but only theirs. (If anyone figure out how to do it,

Please note that so far you are not using any of the APAS system. The APAS capture system which we developed over the last 30 years and started from only recording coordinates from 16 mm film to capturing analog video. At the present there is no reason to re invent the wheel. The capturing cards that available on the market coming with their own capture software and they are very sophisticated and adequate. We at ADI Inc. only had to develop the interface software to theirs in order to extract the high speed video fields and to be able to trim more accurately the video sequences.
In the next page you will learn the setups necessary to make it happen.
