a lot of it is in the lighting.
^ This. People overlook lighting. It's not just a matter of using bright lighting but controlling every aspect of lighting to make conditions optimal for the sensor (or even film) used in the camera.
I'm a noob when it comes to video.
Then take some classes and/or read up on video and lighting. You're not going ot pick everything up from reading discussion forums.
If the regular iphone cam shoots in 1080 then wouldn't the quality be the same as the GoPro? Is 1080 all that counts
No. Again, you need to educate yourself. Resolution is just resolution. There are many factors that affect image quality. Just as with digital still cams, MP tells you nothing about the entire image quality of a camera. Does HP tell you everything about a car? Does GHz tell you everything about a computer? Does your age tell you everything about a person? One metric isn't going to accurately describe anything.
Even if you know nothing about video, think about it. If 1080 was all that mattered then why wouldn't all 1080 TV shows be shot with the Go Pro?
or do cam corders have special features that make their picture even more clear? I'd rather not spend more money if I can get the same results with my iphone. I thought that perhaps I was doing something wrong since my recordings didn't turn out great, perhaps didn't focus it enough or too much light etc...
Yes and no. Better cameras help but even the best tools won't produce quality images in the hands of the inexperienced. You can certainly Google around and find excellent photos (as an example) taken with iPhone cameras by professionals. You'll also find countless horrible photos taken by amateurs. Again, it's a matter of knowing your equipment and how to produce the best images given the characteristics of the camera.
