Thanks for the prompt reply.....Please explain your last instructions (turn off all automatic features in Video View). Where is this?
Also I have an old 4S, would I be served better using that for my lap timer/video work?
Thanks,

I have been using petrolhead for a couple of years. Always good video, using Ram mount to windshield with suction cup up and arm down, until today. The video image is best described as wavy, and pulses in and out of focus. Help what am I doing wrong?
