FWIW, I don't trust the frame rate of any video too precisely. It really depends on the equipment. In my work I have carefully analyzed some footage and found time stamps from individual frames deviated from the average frame rate by a few percent. With proper analysis you can quantify the effect on what you are really trying to measure. Or just take your results with a grain of salt.
