Best input format for PPro 2.0?

Hello,

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.
