Like the Canon Kiss 2, the D5000 comes with Live View. Unlike the Kiss 2 however, the Nikon takes full HD video. Press the LV button and then hit OK to start filming.
Recording resolutions are:-
1280 x 720
640 x 424
320 x 216
You can record for only about 5 mins or so on 720p before the recording stops. Looks like its due to heat. SLR with video capabilities seems to be relatively new. There is no auto focus either meaning that you should kit yourself with a wide angle or learn how to manually focus as you record stuff. A sample below of the office taken a while back. Looking forward to SLR's having stereo video recording and auto focus. The D5000 records in mono - crap mono.
Now for some side by side comparison shots.
The Canon Kiss 2 has a kind of electronic bleep with a sharp crisp "kbleep!" for the shutter noise. The Nikon on the other hand is a dull "Kuroop!" From the shutter noise of the Canon alone, I can take a photo and know what settings I need to get the next best shot but for the Nikon I guess it will take some time to get used to.
I think this was taken on the highest ISO setting of 3200. The road was very dark but the D5000 managed to do a fair job of making out the surroundings despite the low light with no tripod.
I've only been using the Nikon for a wee bit and as I don't have decent lenses yet. I'm still using my Canon as my main SLR.
Right now I could invest in getting a 18-200mm, 10-22mm and a macro lens for the Nikon but I don't really see the added value of doing that as I already have those lenses for the Canon. I'd rather get a Canon Kiss 3 which can take videos so until some decent lenses fall into my lap, its unlikely that I would be using the Nikon much - but my waifu said that she wants to use it ^^
