Hello, I am trying to analyze videos recorded at an at angle. To know software if was giving me correct results i recorded a ball thrown in the air with a camera perpendicular to the ball and another camera at an an angle. Since the ball follows a projectile motion V(x) should be constant and V(y) would be varying. But when i compare results on the two videos with same (frame rate). They give me different numbers. Wanted to know can this software calibrate videos at an angle? If yes Could someone tell how to go about doing it?
