Tracker is free video analysis and modeling tool built on the Open Source Physics (OSP) Java framework. It is designed to be used in physics education. Tracker video modeling is a powerful way to combine videos with computer modeling. Tracker includes a Java JRE runtime and Xuggle video engine.

Features and Highlights
  • Manual and automated object tracking with position, velocity and acceleration overlays and data.
  • Center of mass tracks.
  • Interactive graphical vectors and vector sums.
  • RGB line profiles at any angle, time-dependent RGB regions.
  • Model Builder creates kinematic and dynamic models of point mass particles and two-body systems.
  • External models animate and overlay multi-point data from separate modeling programs such as spreadsheets and Easy Java Simulations.
  • Model overlays are automatically synchronized and scaled to the video for direct visual comparison with the real world.
  • Free Xuggle video engine plays and records most formats (mov/avi/flv/mp4/wmv etc) on Windows/OSX/Linux.
  • Video filters, including brightness/contrast, strobe, ghost trails, and deinterlace filters.
  • Perspective filter corrects distortion when objects are photographed at an angle rather than straight-on.
  • Radial distortion filter corrects distortion associated with fisheye lenses.
  • Export Video wizard enables editing and transcoding videos, with or without overlay graphics, using Tracker itself.
  • Video Properties dialog shows video dimensions, path, frame rate, frame count, more.
  • Fixed or time-varying coordinate system scale, origin and tilt.
  • Multiple calibration options: tape, stick, calibration points and/or offset origin.
  • Switch easily to the center of mass and other reference frames.
  • Data include units (SI metric units by default, settable length and mass units).
  • Protractors and tape measures provide easy distance and angle measurements.
  • Circle fitter tool fits circles to 3 or more points, steps or tracks.
  • Define custom variables for plotting and analysis.
  • Add editable text columns for comments or manually entered data.
  • The data analysis tool includes powerful automatic and manual curve fitting.
  • Export formatted or raw data to a delimited text file or the clipboard.
  • Display measured values using custom number formats if desired.
  • Tracker saves Tracker projects as TRZ files ideal for the Library Browser.
  • The browser shows recently opened Tracker projects in a "recent local file" collection.
  • The browser opens local collections of videos and Tracker projects.
  • The browser opens online collections of videos and Tracker projects.
  • Search for projects and other resources by name, author, keywords or other metadata.
  • Build and share your own collection of Tracker projects, videos, and support docs.
  • Integrated searchable help and diagnostics.
  • Full undo/redo with multiple steps.
  • Page view displays Html instructions or student notes.
  • Annotate videos with colored line drawings and labels.
  • User preferences: GUI configuration, video engine, default language, font size, more.
