Free fall - value of g too big

Hi, I filmed a free fall of a metal ball and analyzed the movement with tracker. However, no matter what I do I always get ca. 11 m/s^2 for g (parabolic fit to y-t-data). What am I doing wrong? Do I have to keep a minimum distance to the scene to prevent distortion? I filmed it from ca. 4 m distance. free fall distance was about 80 cm. I use an Iphone 12 and the latest version of Tracker (6.0.10). Thank you in advance Christof
