Topic: Kinnovea more accurate than Hand Timing
I was a High school and Elementary Coach in Track and Field of Sprinters. We couldn't afford an electronic timekeeping system. So I was using an IPad and iPhone to do video analysis of my athletes. In training and time trials for distances below 250m, we would use Kinovea. Kinovea was particularly handy if athletes blanket finished closely in races.
I got a very good comparisson when I used the software to compare against electronic times.
I started the timer from when the smoke came out of the gun. Its a good video cause you can clearly see the smoke coming out of the gun and a good view of the finish line. Although the camera had a straight view not on an angle.
Hand Times for this race were 11.9, 12.2
Kinovea Times were 12.20, 12.34, 13.06, 13.16, 13.26
Electronic Times were 12.26, 12.42, 13.06, 13.16,13.44
So not bad Kinovea guessed #1 and #2 within .10 seconds and #3 and #4 accuratley. Compared to hand timing which was .36 and .22 off.
