Hello Zhang Li,
Thank you for your message. The REALCAP and CAPTURE software modules were
created for capturing analog video from a computer controlled VCR in an
older version of APAS software. WE have many users that are still using
that hardware and that is why the software modules are still included in the
download. You will not require these programs for video capture.
You should use the Pinnacle software to capture both the Digital Video and
the Analog Video. Just be certain that the video is saved in Microsoft
compatible AVI format. Also, do not perform any tasks other than capturing
the "raw" video. The Studio software allows you to select options such as
"Make Movie" and we do NOT want to use this since this changes the timing in
the files. Just capture the desired video and then exit the program.
After capturing the video, the following steps are usually performed in a
TRIM module - used to "clip" and synchronize the desired video for
DIGITIZE module - used to digitize the individual camera views. Up to 6
views can be digitized simultaneously.
TRANSFORM module - used to convert the digitized point locations into
FILTER module - used to remove any random digitizing errors
DISPLAY or APASVIEW modules - used to display the results for analysis.
I hope this helps to answer your questions. Please do not hesitate to
contact me for any further information.

We are currently using the STUDIO DV capture board made by Pinnacle
Systems. However, any frame grabber that is IEEE 1394 "FireWire"
compatible should work with the JVC camera.
The STUDIO DV board includes capturing software, however, the "high-speed"
video has to be extracted into single images. JVC accomplishes the
"high-speed" by slitting the full size image into either half or quarter
size. I have attached a description that helps to explain this process.
This is written for NTSC format, but the same principle applies to the PAL
The Ariel Software Drivers for the JVC camera are required to access the
100 and 200 Hz video. These software drivers are NOT included in the Basic
APAS software and would have to be purchased separately at a cost of
$3,500.00 USD. NOTE: Also it is recommended to use the SP mode (not LP
mode) for recordings.
I hope this helps to answer your questions.
