I watched Nikons video of the 3100 and it that video it's not in manual. You can see exposure change here and there.

Sounds like manual controls to me

I had had an interesting talk with a Nikon's man a while ago -- posted @ reduser.net where this camera had actually been referred, here is.
It does seem promising:

* low bitrate H.264
* only 1080p24 and 720p30
* 230Kdots 3" LCD
doesn't look promising at all... unless...
* the encoder is good enough that it works well at such low bitrate
* it doesn't use line skipping (in my book that would be much better than having 720p60)
* it outputs fullres HDMI while recording (a 7" monitor is bigger but not much more expensive than a zfinder)
or maybe this is just a toy and we can only hope the D95 (or the 60D) is the one to get it right... (I really want something without line skipping, please)

Besides the Nikon color rendering, the best one of the DSLR realm IMHO apart our well-known issues with resolution/definition of before and poor encoding to be seen (at least, we'll be here to see the improvements), this does seem promising:
AF-area modes for live view and movies - four AF-area modes depending on the subject: normal-area AF, wide-area AF, face-priority AF, and subject-tracking AF.

Looking at dpreview there is shutter and aperture info in the display so manual seams possible. There is a flicker reducer 50/60hz which changes sample rate ( sensor readout? ) to reduce or eliminate screen/bulb flicker.
I miss 50/60p but it's nice to see Nikon stepping up the movie mode.

looking at the clip here...
http://imaging.nikon.com/products/imaging/lineup/microsite/d-movie/en/
I see no aliasing, but that could be because of the reduced res, or because someone successfully avoided it (I'm pretty bad at that game, but I know others are better)
what I see is an obscene amount of jell-o: a flower gently blowed by the wind should not wobble, period
in any case, we'll have to wait and see... and remember it's the cheapest Nikon model: if it comes close to the current D3000 prices ($450, instead of the D3100's suggested $700), or if it indeed isn't line-skipping, then it will be a serious option for some budgets/needs (I think I might be better at avoiding wobble than I am at avoiding aliasing)

To little to late nikon. The majority of the film industry is already on board with canon. I waited, and waited and waited with my d90 in hand waiting for a firmware or something that woudl allow me to stay a nikononian as i had been for nearly 30 years, but you didnt respond.
Canon, took the initiative and took control of a market that you created, and now you think throwing the market a small bone all this time later is going to make a difference?
All the people who ever cared, have already switched camps. I wont be switching back for this.
Sorry.
jon!

the bitrate is indirectly stated in the FAQ:
http://imaging.nikon.com/products/imaging/lineup/microsite/d-movie/en/faq/index.htm
1400MB/10min = 140MB/min = 2.33MB/s = 18.66 Mbps
that isn't necessarily insufficient, but the coder will have to be good, otherwise there'll be mud
(my "2001 A Space Odissey" BluRay comes at 13Mbps and looks fine; that's an extreme example, as there's so little image entropy in most of that film, but many others come close to 20Mbps and some of them are OK)

The bit rate there is because of the aspect ratio of 2001 - if it were 16:9, it would be far higher, maybe even double.

It's about time they went full HD, it's a low end camera so not expecting groundbreaking but would have liked it to have at least matched the T2i with 1080p 25p...
Hopefully this is a sign of a step up in the game for Nikon. What I want is full HD and that amazing noise reduction chip from the D3s

no, it's entropy: the bluray is VC-1 at 13.1 Mbps for 1920 x 1080 (1.778) at 23.976 fps
(I know VC-1 is not AVC, but in terms of efficiency it's basically the same)
EDIT: (not right, corrected below)

so far, only that it is totally needed: the LCD is 3" but only 230K dots (320x240 or so)
in any case, consider this size comparison, to see what this camera is supposed to be:
http://a.img-dpreview.com/previews/Nikond3100/Images/comparedtocanonsony.jpg
at current D3000 prices, I could buy one of these just to kill time for a year or two as I wait for some manufacturer to give me something like the t2i, but without line-skipping, for under $1000 (so far, my strategy has been to spend my money on lenses, tripods, mic, H4n, etc., and borrow the body; for $400, I could stop nagging my friends)
(did I say one or two years? I mean: I want the 60D to be that camera, and I want it for $900 in september, thankyouverymuch)

2001 is 2.21:1 - so most of the encode is black as it's not stored in anamorphic, it's a 16:9 file with bars. The black compresses to near 0 bits per frame.
