I've had my D7000 a couple months now and taken 3-4000 shots. Recently I started using it to take some video and all was well until today.
While shooting a video, it literally just 'froze' and refused to do anything. Switching it off...no effect. I popped the battery for a few seconds and the camera started up again. I noticed the "ERR" flashing on top display after switching the camera back on. I'd click the shutter release button a time or two and "ERR" would disappear.
However, each time I tried to resume shooting the video, same thing would occur (i.e., the green "Info" light would go nuts and then everything would freeze). I must have popped the battery 3 times. In the middle of all of this, there were 3 or 4 segments where I could shoot 5-10 seconds of video before it would stop recording (but not freeze).
Finally, I gave up with the video and tried shooting stills. The shutter would release and I would get an image preview on the LCD however, after importing the files to my computer - none of said stills were on the card. In addition, many of the video segments were of an "unknown format" - no doubt corrupted by whatever was going on and/or the yanking of the battery.
Some additional items: - Shot video 30 minutes earlier without any issues whatsoever. To the best of my knowledge, no setting changes were made. - Camera was in P mode. - Battery was about 31% charged. - Nikkor 18-200mm VRII lens. - Sunny and about 80dF outside in a beach setting. - Camera is set to AF on Faces in Movie-mode. However, it was having a heck of time focusing at all (the little yellow boxes rarely were showing up). There was a large crowd and the main subject was a sea turtle (lol). - I was manually zooming the lens in/out. - I have 2 identical 16GB Class 10 memory cards inserted and configured to be duplicates. The cards had maybe 30 stills and 1-2 mins worth of video - so basically empty.
What happened? Card failure? Camera failure? Battery issue? User failure?
Any chance you overheated the sensor in the prior takes? There is a 20 minute video limit because of overheating. Especially if the sun is beating down on it. Beach environment, the camera should probably be covered so it is in shade when not in use.
Overheating should not lock up the camera as it just drops out of live mode. I think a corrupt card (or two) is the likely explanation of the symptoms. A different card should allow the camera to operate properly. I it does not work with a different card (known good card) than I think a cal to Nikon for service is in order. The situation you describe does not sound like a common failure mode but it does seem to be related to the way data was attempted to be written to the cards.
Before the beach we were a hundred yards away in an outdoor setting shielded from the wind and it was stifling hot. I shot stills for probably 30 minutes straight there - including maybe 2 mins of video.
What I then noticed at the beach was that after pressing record, maybe less than a minute later it had stopped recording - but still in Live mode. I kept forcing it to record and it kept refusing after a few seconds. That's when the sequence of locking and battery removal started.
Seems like the camera should be able to handle these conditions. Was I really pushing it that hard?
In live view, the sensor is being accessed continually and it will self overheat if left on too long. Nikon has put time limits on video to help prevent overheating.
The first issue is hot pixels as the temperature rises. There have been firmware updates for detecting and removing them so they are less prevelant than before.
However, if the sensor gets too hot, the camera will just suddenly drop out of video mode to protect the sensor. I had a D90 with a five minute video limit and after several recordings, would start dropping out of recording with no warning. This was in an air-conditioned living room. On a sunny hot beach, I can see solar heating to be a factor in the original problem.
In the future, I would see the camera is shaded/covered when not actually in use on the beach, for minimazation of hot pixels if for nothing else.
I had a similar thing happen but I was not in Live View or shooting video. We were on the train on the way to NYC. I handed my wife my D7000 to take a shot, she took the shot and when she handed it back to me, it was frozen with the mirror up and ERR displaying. The only thing that worked was pressing the shutter again. The next shot did the same thing, then I pressed the shutter again and it was fine. It was fine the rest of the day.
It hasn't happened since so I'm just hoping it doesn't happen again.
Those were older class 4 cards. I am now using new Sandisk class 10's.
What cards where you using? I had a similar err when I was using a supposedly Class 10 card and trying to write Raw with a lot of continuous shooting. After reading some reviews on the card came to find out a lot of people had issues with them in DSLRs. I would expect video to be pretty taxing as well.
Anyway I just got my D7000 a couple days ago so am learning a lot myself.
Fer crissakes...Same thing happened again on a shoot yesterday. How frustrating. Yes, it was warm out but I was shooting in the shade.
My data cards are identical 16 GB Class 10 from Transcend. Starting to think they are somehow to blame as one of the recent posters hypothesized.
Would it help matters to only load 1 card in the camera and thus give it only 1 location to write to for video? My normal config is both cards are in the camera writing identically to each card ("mirrored disks" essentially).
I felt somewhat relieved but then I checked reviews on Amazon and it seems I am not alone. Many many folks complaining about their cameras locking up when shooting video. Ok, seems the mystery is solved...now a SOLUTION
What cards are people using for HD Video on their D7000 *without* issue and you are willing to endorse?
I'm using Transcend 16Gb Class 10. I do a lot of burst shooting on a daily basis, filling the buffer, never have had a problem.
I shot some HD video the other day, and no problem. The clips I shot were somewhat short - 10 or 15 minutes was the longest, most were in the 3-4 minute range, but I shot 10 or so clips of that length. I only had 1 card in the camera.
What length videos are you shooting that causes the problem? I can try to duplicate settings, and see what happens.

I've shot close to 4,000 stills with these cards - never an issue. When I try to shoot video - it typically won't go more than a minute, sometimes as little as 1-4 seconds, before crapping out.
I'm sure it's not an issue with ALL cards from Transcend - but mine are definitely suspect.
SANDisk seems to be a very highly regarded brand for SDHC cards. I think I'll pop one of those bad boys in there and see what happens. At least it will tell me if the issue is the camera or the card.
