Click the 
Set Impact
 button once you have advanced the video to the proper impact 
frame. Once the Impact Point has been set, you will see the 
Key Position
 buttons: 
To immediately advance the video position to any one of the key positions, click the 
desired 
Key position
 button. 
Setting a new position 
If you wish to change the Impact Point, or any other position, first advance the video 
to the appropriate frame, and then hold down the desired 
Key position
 button until a 
“new point has been set” message is displayed.  Certain V1 features either require or 
work  more effectively if  the important key  positions  (address, top-of-backswing, 
impact, and follow-through) are set accurately.  These features include 
Tempo
, 
Video 
Synchronization
, 
Trace
, and 
Multiple Exposure
. 
Key positions are required to be sequential (that is, 2 must follow 1, 3 must follow 2, 
etc.).  If you reset a position, the V1 will automatically redistribute other positions to 
enforce this requirement. 
Golf tempo estimation 
When  impact  is  set  for  a  swing  belonging  to  or  assigned  to  one  of  your  existing 
students, the V1 will “estimate” the other positions based on the student’s most recent 
swing.  If the swing does not have a student assigned to it, the V1 will estimate the 
other key positions according to a default “average” swing tempo. 
Non-sport-specific positions 
If you’ve selected to see the 8 non-sport-specific position buttons, you will not see a 
“set impact” button. Instead, you will see these buttons: 
Initially, the 8 non-sport-specific key positions are evenly distributed through the video. 
Position 1 corresponds to the beginning, and 8 to the end of the video. 
Comparison 
The V1’s video window may be split to allow you to open and control two 
videos simultaneously.  The 
Compare
 button will activate Compare Mode.  
Click the 
Compare
 button again to exit Compare Mode and return to use of 
the entire video window for a single video. 
In Compare Mode, the video position slider will split into two, and there will be three 
new buttons placed between the sliders.
