HOW DO I EDEIT VIDEO FROM A D800

I can't tell if this is a troll or not.

That said, all dslr footage is edited in the same manner. Go to Bing/Google, search for "how to edit dslr video".

You are essentially asking for a book series worth of information in a single forum thread. No one can provide the full spectrum of information you are in need of, but you can find all of the information you seek out there already on the net.

But, I'll try to start you off: You can edit D800 footage in Premiere Pro. You edit D800 footage in it like any other footage, and like most other NLEs.

If you don't know what an NLE is, go to Bing/Google, and search for "what is non-linear editor".
