There are a number of stages to each video project.  These are:

  1. Record Video of Movements 
  2. Capture video to PC and process
  3. Create a project definition file
  4. Create a KA Image Set
  5. Digitize the body points
  6. Analyse the data you have collected.

Simplified notes on each of these stages follow.  If you are wanting to undertake a university level biomechanics study, you should ask your lecturer to obtain the full KA manual available from the official site.
