On March 25, 2013, OpenTrack-0.11.0 was released. Updates are pushed out via
, although you
can get your first release here. You can also get
older versions of OT here on SourceForge. OT is now documented on
Disambiguation: There is another OpenTrack project as of 2009. This project is a Web
Application Framework for boosting developer productivity. If you are looking for

The OpenTrack website is intended to a be resource for software and hardware pertaining
to motion analysis whether it be for biomechanics or physics related purposes.
It was created because of the lack of entry level motion analysis solutions for educators
interested in introducing their students to the field.
While there is no question that many commercial systems are very high quality, such
systems are usually cost prohibitive for educators to purchase.
Additionally, as digital cameras are now virtually ubiquitous and doubling in resolution and
frame rate every few years, it is now possible to do science that is on a par with that done
a couple of decades ago using very low cost hardware.
This website contains several components that may be useful to educators and beginning researchers.
- OpenTrack Software for 2D Motion Analysis.
OpenTrack allows users to track discreet points in 2D video, and calculate various 2D
physical parameters. The software is camera-agnostic and is capable of reading a number of
video file formats including *.avi, *.mov, *.mpg, and *.ogv using the ffmpeg library.
The current features include:
See the OpenTrack screenshots and workflow for more.
- Graphical display of linear kinematics including position, velocity, acceleration,
momentum and force.
- Graphical display of angular kinematics including angle, angular velocity, and
- Graphical display of kinetic, potential, and total energies of a marker, as well as
some summary information regarding average power dissipated via gravitational potential
energy, average kinetic energy per unit time, and change in energy over time.
- Manual digitizing of videos for instructional use.
- Auto digitizing of videos given high contrast (retroreflective markers) and/or fast
frame rate (with respect to the motion captured.
- Stick figure (linkage) and marker overlay to images
- Scalable vector graphics outputs
- Built in tutorials and fast learning curve.
- Exportable overlay and graphics in the form of video
- JSvg Graphics Library for Mozilla
This graphics library is useful for creating Scalable Vector Graphics plots of scientific data and is has the following modes: scatter plot, line plot, bar plot, histogram, stacked barplot, and stacked histogram modes.
