Does it actually change the final exposure or does the shutter speed change then the gain changes to keep the exposure the same? Definitely confusing, but also a little fun to dissect.

Check out the screen caps (they are from the D3 review). Looks amazing, but that is for still images. No idea if they apply any compression to LV out. The frame rate should be 24.
See, THAT is why it's confusing. Because I have no solid idea of what the camera is doing once the AE-L is off. That's why I asked Joe to go outside and set the shutter then tell me if it actually does anything, because if you do it indoors then lock it THEN go outside then it's at the right shutter to begin with.
On first and second look: Easy Exposure adjusting changes the shutter speed. Aperture mode kinda reflects that in that on the readout as well. I'm gonna keep testing it and do some more recording right this second to see if I can see the shutter changing in manual mode.
Does the easy exposure adjustment do anything when AE-L is on? If anything it would most likely cancel the lock.
Ok so again - we seem to have aperture set in a controlled manner, even with a modern lens. Shutter speed MAY be controlled by this easy exposure adjustment (knock on wood). What about gain? No choice but auto? Can you do exposure compensation (not the easy one, the regular one) with AE-L? With auto gain off (however that works - same as auto ISO?), you would be able to control gain with regular exposure comp, since aperture and shutter are already supposed to be locked.
The other thing is, why would they call it easy exposure adjustment if it was used with auto gain? There would be no exposure adjustment in that case. So there must be a way to turn auto gain off. On all Nikon dSLRs with auto ISO (goes back to ~2002), if you use manual mode and set aperture and shutter, it will still adjust the ISO to meet the exposure it wants, and you can also apply exposure comp which just biases the meter. Works well if you NEED a certain depth of field AND shutter speed, as long as you are within the ISO range. It would be neat to turn this on and off in movie mode because frankly I could see the same dual necessity there, as well as stills.
Is this the same easy exposure adjustment that's available in still mode? Or is it a liveview only thing?

Nope. It actually doesn't even Cancel the lock. I just went outside and recorded video going back and forth with the AE-L and the Easy Exposure. Engaging and Disengaging the lock so that you guys can see what I see.
Uploading.
VIMEO ETA: 30 Minutes which means about an hour, sadly.
Same Easy exposure adjustment that's in Still Mode. It works with video mode, never thought to try it because I actually never use it in still mode. Just happened to go "Hmm I wonder..." last night and it worked. Go figure. And, I don't think this is listed in the manual!
I also just activated auto ISO and set it at a max of 400. Gonna go back and forth between 3200 and 400 to see if this actually effects how much garble is in the image.
I just registered here to say huge thanks to Kholi and you guys for taking the time to test the movie mode so extensively because as purely still shooting Nikon user, your video expertize is invaluable for video illiterates like me.
I found this thread through dpreview and it seems many of the still shooters there are very happy about your testing.
Keep up the good work here and looking forward to more of your testing and analysis.

charging my battery. i've officially enlisted in the D90 army.
Thanks alot. I seriously wish that it was just as straight-forward as all of us had hoped. Just about nothing that applies in DSLR mode applies to Movie mode. =(
And, I think that's what we were all hoping for.

One thing I like over at DPReview is the guy that's talkin' like he's put his hands on the D90. It's clear that we were all expecting the camera to be able to act, in video mode, just like it does in still mode.
It doesn't.
And I'm not trying to get a grasp on the STILL mode. I'm not ASKING how ISO works, I'm askin' how it's applied to the damned camera in Movie Mode. I don't give a damned how this camera works in Still Mode right now, I want to know what effects WHAT in Video mode. Love having my word misconstrued, WISH loudmouth people would pony up their own money and put their fingers on the camera before yappin'.
Pfft.
It doesn't.

kholi how much shooting time were you able to squeeze out on a single charge?
That's hard to say. I haven't been straight shooting at the moment. Just fiddling with menus to see what works with D-Movie and what does not. When I actually start shooting at a constant rate I'll let ya know what I'm getting.
The really worry is the auto-shut-off feature for LV mode and exactly how much noise the 'overheating' adds to the image.
As far as SD cards: one 4gb, haven't deleted any footage yet and I still have over half the card left.
Yum.
Vimeo says still converting, sadly. I'm gonna H.264 compress it right now and throw it up on my site. Vimeo's not being a good kid at the moment.
Kholi, if you put it on Blip tv, you can give us a link to a quicktime page. Then you don't have to worry about your site getting killed. Also, Blip doesn't do any compression.
