• If you have test program with video file use loop program function:
  • Click on menu Run→Run loop or on Run loop button on toolbar window
  • Dialog window for loop parameter selection display.

• Select “Start line in next loop to line 2. This parameter means that test program in loop mode start only on first loop from line 1 on test program and next loops started from line 2. Reason is that on line 1 is reading video file and it needs to be done only ones, in the next loops frame from this file will be read (and it starts on line 2)
• Select “Repeat loop time [ms]” value. This value sets time between loops. If you select 100 ms loop will be executed each 100 milliseconds, if you select higher value loop will be slower.
