Kinovea comes in two flavors: a stable version and a beta version.
The main difference is that the beta version contains more experimental features, doesn't have a fully complete manual, and the file format is evolving.
In order to graduate from beta to stable, it is important that as many people as possible test the beta version and give feedback.
The .exe links are installers and the .zip links are self-contained "portable" archives.
The user interface for the stable version is available in the following languages: English, French, Spanish, Italian, German, Portuguese, Dutch, Romanian, Polish, Finnish, Norwegian, Greek, Turkish, Chinese, Lithuanian, Swedish.
The beta version also includes: Arabic, Danish, Czech, Korean, Russian, Catalan, Japanese, Serbian Latin, Serbian Cyrillic and Macedonian.
Kinovea is a free software under the GPL v2 license. Please have a look at license.txt in the installation directory for more information.
You can use it for free for any purpose, including personal, academic or commercial. You do not have to ask for permission to use it in your research, university courses, bike fit shop, physical therapy clinic, or any other business or hobby activity.
The source code for Kinovea is versionned using git and hosted on github.
