How to learn to use my Nikon D3100?

I want to begin recording and editing videos with my new camera; are there any videos online I can watch to learn the basics on how to use this specific camera? I have only the original lenses that came with the D3100. Any helpful information is appreciated.

Why did ya buy a camera then?

It should have a "guide" setting

Try reading & studying the Owner's Manual for your camera. This video tutorial will also help you:

1- Ready your manual

2- Take a basic DSLR course…
Some municipalities offer these for next to nothing through your local library (my city offers thousands of courses like bread baking, sewing, basic photoshop, portrait lighting… For about 150$ for a 5 session course)

3- Pick up some books…
Scott Kelby's 4 book box set is a good introduction to photography.
