Anybody familiar with adobe premier pro

So i'm trying to edit a video and i'm using a nikon d3100 and when i import a video its not showing all the frames or scenes. Its like skipping frames but you can hear the whole audio. You know in the beginning where you choose the settings for like the type of sequence or something what am i supposed to choose?

Added (1). I'm using cs4

Which version of premiere are you using? If you are using CS5 or 5.5 skip the section in the beginning when you have to choose settings. Adobe made it much easier for people who don't know which setting to chose. When you skip that option, your new project will open as usual, bu there will be only blank sequence tabs. That's ok. Import your footage from your Nikon into your project bin. Drag one of the files on to the new item button located at the bottom of the project bin. It automatically creates a sequence with the right settings for your video. Takes all the guess work out.
