  Motion tracking data and slider

  Posted by Michal Lukaszyk on February 10, 2015 at 1:38 pm

  Hello
  I have a problem with expression, slider control and scaling parameter.
  First I made the motion tracking on my movie and apply this data on the null.
  and now I want to control scale parameter using expression and sider.
  How to do this? My tracking data changes between 94% to 105%. How to write expression … when the slider parameter is 0 i have 100% scale parameter (and tracking value “don’t working”) and if i move it up or down it increase or decrease tracking value and when slider value is on 1 it give me true tracking value. uffff

  Thanks for help
  Mike
