I have a similar problem. I am recording in HD which plays back perfectly on the camcorder. However, when I capture any footage as HD which has a pan or zoom in it then the footage is jumpy and this effect is carried through to the final output medium. It is most frustrating and I would love to get rid of it. I am a newcomer to PPRO and any complicated jargon will only make my eyes glaze over. I am using CS4. Can anyone explain my problem in words of one sylable?
