The build in flash, will be useful within several meters (15 to 20 feet) if it is really dark.
Your camera should be capable of taking pictures in poor light conditions. Try to shoot in automatic mode. The mode dail to AUTO. (green camera symbol). Then view the picture with info. There you can see the ISO, Aperture and shutter time. From there you can experiment for darker or lighter pictures. For this you can choose M, A,S or P.
In each of these modes, you can use the following steps.
On top of the camera, close to the shutter release button you see a little knob with a +/- sign. If you press that button, you should see a 0.
If you see a - figure, this means the picture you shoot all be darker than normal. If you see a + sign with a figure it means the picture will be brighter. While pressing that button and turning the command dail, you can choose -3 to +3 EV. That is much darker and much brighter.
If you shoot many pictures in bad light conditions, you could buy an external flash. A Nikon flash will work very good and automatic, with your camera, because camera and flash will communicate and help each other to make better pictures. Cheaper external flashes can work too, but most of the time you must change settings manual on the flash. Never use old flashes, that were build for analog cameras. They sometimes switch with a voltage higher than your camera can handle. The camera can be damaged by such a flash.

In either mode, you're zooming by turning the zoom ring on the lens? In live view mode, if you zoom in by pressing the magnifying glass button, all you're doing is zooming the display, not the image itself.

Rotate the Live View switch to the LV position. Focus by pressing the shutter release button halfway. Start recording by pressing the movie-record button. Stop recording by pressing the movie-record button again.

Full details are in the "Recording and Viewing Movies" section of the manual (page 107 in my copy). If you need a manual, you may download a copy here.

If your lens has a Nikon mount then yes, you can use it on the D5100. You'll have to switch to the Manual exposure mode and you won't get any exposure help from the camera's light meter.

The normal mode for this camera, as it has been for SLRs for half a century, is to use the viewfinder to compose your pictures. If you want to use the Live View feature, you need to activate it by rotating the Live View switch beside the mode dial. Full details are in the "Live View" section of the manual (begins on page 99 in my copy). If you need a manual, you can download one from

yes by using some burning tool that convert it. or used video converter

The Nikon D5000 must be set in "Live View" mode before you can use the rear monitor to take photos. There is a button that says "LV" to the right of the LCD screen that sets Live View to on or off.

if you are new to DSLR. set the menu setting default.
however there is lv button to see in live mode.

If your screen works in playback mode, the screen and flexible circuit boards are intact. To shoot an image using the LCD screen you must first activate the "live view" function in the setup menu, and then press the live view (Lv) button to view your image on the LCD.
