Re: Optura



The premiere program is Videopoint http://www.lsw.com/videopoint/.
It has the distinct advantage of allowing students to see several
kinematic quantities at once on the screen. Unfortunately World in
motion can not do this http://members.aol.com/raacc/wim.html.
However, World in Motion is cheaper. Another good alternative is Bob
Beicher's program VideoGraph available from Physics Academic
Software http://wasnet02ws.physics.ncsu.edu/pasnew/. There was a
free program called VidShell available at one time from Doyle Davis.

Both VideoGraph and VidePoint are similar. Each has added features
of the other. VideoGraph is for MacIntosh only, while VideoPoint is
Mac or PC. World in Motion is PC only. VideoGraph may be easier
for students to use, and World in Motion is very easy to use.

For ease of use and quality of results, I think VideoGraph is better
than VideoPoint, but VideoGraph is a bit older and has a serious
limitation--it can handle only 128 data points. It isn't hard to
visualize a situation in which more than 128 points are needed. I
have talked to Bob Beichner about this and he agrees that the limit
is a problem, but says that he has no plans to upgrade the
application. Increasing the data capability would be quite
labor-intensive and he has neither the time nor the funding to
undertake that task.

Let's face it. People use a Mac because they want to, Windows because they
have to..
