Tracker 4.72 - Aug 27, 2012 at 7:54PM

Hello all,

Tracker 4.72 installers for Windows, Mac and Linux are now available from both the Tracker home page (http://www.cabrillo.edu/~dbrown/tracker/) and ComPADRE (http://www.opensourcephysics.org/items/detail.cfm?ID=7365). This release fixes an important bug in version 4.71 that sometimes causes Tracker to freeze when loading trk files.

Be sure to install Xuggle if you do not yet have version 5.4.0. Also, if you have not yet done so, please check out the new Shared Collections menu in the Digital Library Browser which gives you direct access to video collections from LivePhoto and others. See Sharing Your Collection the Easy Way to learn more.

Note: Xuggle 5.4.0 can still cause some videos to exhibit a 4-frame "lag" that is particularly evident when you step the video a few frames forward, then back. I am working with the Xuggle developers to fix this problem, but in the meantime you may wish to use the QuickTime video engine if it available on your machine. Note: you must run Tracker in a 32-bit Java VM to use QuickTime.

Thank you! Doug
