Nikon D3100 stops taking pictures long exposure?

Adobe Premiere Pro CS5.5 Sequence Presets for Nikon D5100?
Can someone tell me what Adobe Premiere Pro CS5.5 Sequence Preset to use for footage shot on a Nikon D5100?

I'm a beginner photographer and have a recently purchased Nikon D5100. I bought the kit lens (18-55mm) with it as well.
I'm helping a friend out with some portraits. They know I'm a beginner and aren't expecting unbelievable quality, nonetheless, I myself want decent quality photos.
Like stated, the only lens I own is a 18-55mm. So what are the best settings and options for setting up my camera for single portraits of people and a few group shots? I'm going to say mainly outdoors for this situation.
So how should I set up my camera?

Canon t3, Canon t3i, or Nikon d3100?
I'm an 18 year old girl who has a love for photography. I've been using a Sony DSC-HX1 and I'm ready for a DSLR.
The three cameras I've narrowed my search down to are the Canon t3, Canon t3i, and the Nikon d3100. And now I really can't choose between the three. I have basic knowledge on ISO and aperture and whatnot. The Sony camera I have now is pretty bulky, so I don't have an issue with bulky cameras. My original plan was to buy the Nikon and buy accessories with the extra money. But then people started telling me that Canon was "better".
So anyone who's worked with any or all the cameras, can you give me your input including pros and cons?

Is there any video editing software not compatible with a Nikon camera?
I'm thinking of getting the Nikon D5100 as my first DSLR camera to do my film and media AS level work on, because the cameras in my college aren't brilliant. My first piece is for Film Studies and needs doing in December, I have to create a film. However we have to do the editing in college after Christmas. So before I go buying the camera I have to make sure it works with all types of editing software (so I can edit at home as well as in college, for when I make my new YouTube videos) so is there any out there, that are not able to work for Nikon cameras?

Ok well there's this professional camera "Nikon d3000" it's really good and it's good for pictures and videos, I was thinking if I buy that, I can take cute pictures and make YouTube videos!
But I might want the Xbox for minecraft, that's it, lol kinda dumb I know. I'm not sure which one I want, but I can't get both. So which one should I pick?

Shutter speed decreases in live view?
Hi, I'm using a DSLR (Nikon D5100, to be precise).
Suppose I set the shutter speed to 1/30, when i shoot using the optical viewfinder everything turns out fine.
But when I shoot the exact same picture ( same light, aperture, zoom, angle etc.) in Live View, it changes.
Manual Mode:
Optical Viewfinder: Shoots fine at 1/30.
Live View: The shutter speed still SAYS 1/30 but it visibly takes much longer. Hence, if my hands shake a little the picture is blurred. But if they don't shake, the picture turns out the same.
Auto Mode:
Optical Viewfinder: Shoots fine at 1/30
Live View: As soon as i switch to live view, the camera changes the shutter speed to 1/8 (or whatever it wants).
Basically, it seems that the camera needs to make the shutter speed longer in Live View for the picture to turn out the same way it would have when using the viewfinder.
Why does this happen?

Why do pictures I take with my Nikon D3000 come out blurry?
I don't have vision problems and I don't suck as a photographer, but every photo I take without Autofocus comes out blurry. I don't like using auto but if I don't my pictures are always slightly off. They look great small, but then I blow them up and it looks slightly blurry, making them unable to be enlarged without looking bad.
I tested it and when I use auto focus, my subject looks slightly blurry, but the photo comes out clear. What could be causing this and what steps could I go through to fix it? Is it worth repair or should I buy a new camera/lens and how can I troubleshoot on which to purchase?
