shooting from a helicopter

About 3 weeks ago, i went on shoot in a Helicopter to shoot some scenics for a indie film we are shooting. The pilot insisted on using a borrowed Sony Z-7u which was mounted in his pan tilt unit on the front of the JetRancger. (I wanted to use my Panasonic HMC-150, because it would more closely match the HPX-170 we're shooting the majority of the footage with. I set up the camera to shoot at 720 24p. The results looked terrible with a high frequency jitter in the picture. The pilot recorded a 488i feed of the composite out of the camera, onto a Sony deck, and he says the footage looks gourgeous. Bottom line, the pilot says the issue is the 720 24p, and that I should have shot it at 1080 60i. Is there any truth to this?
