MotionSpeed Help
These pages provide help
documentation for the velocity analysis tool MotionSpeed.
 What is MotionSpeed?
MotionSpeed is an application designed to analyze motion
in videos. The key focus of the application is to graph the velocity of
moving objects. You, the user, simply click on the video where
the object is, the software then calculates the velocity of the
object.
Very Important,
Video Calibration!
Before MotionSpeed can calculate the speed of motion in the video
it must be calibrated for you camera.
The calibration is performed by
placing the calibration strip (included in the box) measuring a distance
of one meter in the video.

How can a video in MotionCoach be
quickly launched into MotionSpeed?
One simple click of a button. A button on the gallery is
called "MotionSpeed", see the button below. To view a video in MotionSpeed
simply select the video you want in the gallery, and press the
"MotionSpeed" button.
How
are postion points placed on the
video?
In the picture at the top of the
page you can see a video with serveral red points placed on
it. To place a point on the screen just move the mouse on the video and
click the mouse button. A number will be placed on the screen and the
video will be advanced one frame.
After a minimum of three points
have been placed on the video you can calculate the velocity of the
object.
How are position points
Moved/Changed?
If you
move the mouse over an existing point and click the Right mouse button,
the point will be removed. The next point placed will have the same
number as the one just removed.
Before the velocity can be
calculated, all points must be in sequence with no gaps. For
example you place points 1 through 10, then remove point 5, the
calculation of velocity will not work .
How do you Graph
the data?
Once
the points have been placed of the video, press the "Graph Data" button on
the bottom of the window.
Can
more than one graph be plotted?
Yes. You must delete
all the points and place other position points on the video. Click the "Graph
Data" button. You will see two graphs allowing you
to compare the velocities.
Up to 16 lines can be
ploted.
Are
there special requirements for
the video ?
Yes, but
they are simple.
Simply configure the video
capture module to caputure at 30 frames per second. All the velocity
calculations are based on 1/30th of a second between video frames .
If you capture videos at a different frame rate the velocity results will
be wrong.
Can the
results be printed?
T
he File
/Print, or Print Icon can be pres
sed resulting in a
printed report of the video and the graph.
Can I
zoom into the video?
Yes, the
video control works the same way as the Play Control in MotionCoach. If
you press and hold down the "Ctrl" keyboard key and click in to the video
with the mouse button, you will zoom the video, to back out, click on the
right mouse button.
Also the tool bar can be used
to zoom the video.
Customize the Application?
Yes you can. Click on the menu option "View/Customize" to open a application customization
window. You can change the colour of the background, colour
and font of the title, create new and customize tool bars, anything
you want!
