APAS DIGITAL VIDEO CAPTURE PROCESS

February 2000

 

 

 

Introduction

 

The following instructions describe the installation and capture process using the SIIG 1394 DV-CAM KIT hardware and ULEADVIDEO STUDIO 3.0 software for use with the Ariel Performance Analysis System (APAS)/Microsoft Windows 98-Second Edition computer systems.      

 

 

REQUIREMENTS

 

The following hardware/software is recommended for Digital Video capturing/editing.      

         a.Pentium II 333-MHz computer (or equivalent)

        b.At least 64 MB RAM

         c.CD-ROM drive

        d.200 MB of available hard disk space

         e.Video Card with 8 MB RAM (PCI or AGP)

         f.Windows 98 Second Edition or later.

 

 

Installation

 

Hardware:

Follow the directions outlined in the SIIG 1394 DV-Cam Kit User’s Manual.  The SIIG 1394 hardware is fully compliant with PCI Plug-n-Play 2.1.      

 

Software:

        1. (where X is the CD-ROM drive letter).“OK” and click on X:\Utility\Setup\Autoexec.exeType in   .Run, and then StartInsert the software CD into the CD-ROM drive. Click on

Additionally, these systems have tested the DV capture hardware and software for correct operation.  APAS computers, with the DV option, purchased directly from Ariel Dynamics, Inc. already have the hardware installed and the software options configured.  :NOTE

Gideon asked me to help with your questions regarding JVC DVL9600 or DVL9800 camcorders in high speed mode.

I think your analysis of the pixel dimensions for these camera models is basically correct.   Assuming NTSC, one starts with a frame which is 720x480. Separating the two fields which are 1/60 sec apart results in a whole field size of 720x240. Then if one considers 120Hz with horizontal panels the optimal size would be 720x120, or vertical panels 360x240. At 240 hz the optimal panel size would be 360x120.

 

As a practical matter, JVC does not split the panels optimally. In practice the real panel sizes approximately are:

            120Hz Horizontal   720x240

            120Hz Vertical   300x240

            240Hz   300x185 

The two cameras in question are great cameras. They offer much higher that standard image rates of a very affordable price. This makes them a very attractive choice for biomechanical analysis. However there clearly is a tradeoff involved, higher image rate for lower resolution. One can get both the higher image rate without loss of resolution but only at a high price.

I hope this helps.
