I'm pulling my hair out here!!!

For some strange reason that I cannot figure out, when I go to render a 3 minute plus video with effects, title sequences and a music track it's only taking the computer one second to do it.
WTH?

I thought I was maybe just doing a render on the instructions and not the actual video, but when I went through the entire process again I know that I am selecting the video. This machine is powerful but not THAT powerful, I have rendered video before and it takes 10 to 15 minutes for a 2 or 3 minutes video, not 1 second. I am stumped, not sure what is happening. HELP!

Oh, and when I do pull up the "one second render" it says that it can't play it. :-(

Well, I think I figured it out. Under render as, I had several boxes checked that I had not had checked before, plus I had not matched media at the very beginning. On the plus side I put this video together in 1.5 hrs the first time, but had it down to 30 minutes the last time! lol

Geez, I panic so easily.
