Overview

MultiLab's Video Motion Analyzer enables you to capture position and time from
video movies, convert this to data sets and analyze the data with all of MultiLab's
analysis tools the same way you would analyze data from the data logger. You can
capture one-body motion or two-body motion. You can select the origin and rotate
the coordinate system.
With the Video Motion Analyzer you can also capture video movies either directly
from video camera connected to the computer or from an external video source such
as VCR.
