Ben Ko 3 years ago I occasionally video runners with a GH2. I find that if i stick the camera on a tripod and photograph the runners coming towards me, the closer they get, the more their heads seem to "bobble" or wobble. I assume this is a variant of the jello-effect people write about when panning, except in this case i am not panning but the runner's are constantly moving forward and up and down. Anyway, any suggestions on how i can eliminate this? Thanks in advance for any advice.
