Hi! This is the screenshot of my system, I used leap motion to make a simple interaction: where the hand is passing the video is reveals. But I have a problem with the tracking of the y ax, it ends at the middle of the frame, it doesn’t go down 
I thought that could be a problem of range so I tried to change the resolution on the movefilein node, but it didn’t work.
The circle has TY values from -.5 to .5 in fractional mode
you should put a “MATH CHOP” after the select, and set a range for the TY.
Look at the input value of the leap, it will show you values in millimetres.
So for example if hand-down is like 10mm and hand up is like 50 mm
you will make a math CHOP that ranges these outputs

Thank you! But how can I visualize the input value of the leap in millimetres?
