Best input format for PPro 2.0?


For HD can anyone tell me what the best file format would be for PPro 2.0? It accepts my gopro video but runs like a dog. It’s a little better with iPhone video but not much better. I’d like to be able to edit smoothly like I do in SD. My laptop has lots of CPU so I don’t think that’s the problem.
