Nikon D7000 Flickering Problems

Hi all --

So far my new Nikon D7000 is doing a good job -- but there's a BIG problem: most of the footage shows "flickering" (going brighter and darker all the time). Even time lapse photos have a noticeable different exposure for every frame. It doesn't show on the live viewfinder. Here's a short clip where you can see what I mean:

Any ideas what causes this? I am pretty upset that the camera ruined a lot of shots that I cannot recreate.

Thanks!
 
Forgot to mention:

All movie setting were in "manual", but ISO settings were in "auto". Camera had an AIS prime lens and I shot in "A" (aperture priority) mode.
 
what kind of light was this footage shot under? Was it flourescent lights by any chance?I had a similar issue recently. I was shooting my daughters ballet class in the dance studio. I completely forget to take into account the flifkering of the flourescent lights and ended up with scan lines on the footage as a result. All down to setting the wrong shutter speed. I am still a novice at DSLR video but I will take more care in future.
 
Just regular light bulbs, no flourescent light, so it can't be the light.

I also did some time lapse (sunset over a building for 45 min until it was dark) and every individual exposure is so different that the final movie looks awful.

To be honest, I'm pretty upset and think I made the wrong purchase.

I think it's too early for that - Use manual ISO for one thing. Also like jc01108 said...once you have your settings use AE lock. Make sure to set it up in your menu so the lock holds with one press of the button.....so you don't have to hold it down constantly.
Same goes for timelapses....you want manual everything for those...otherwise the camera will adjust itself for every little change in lighting, and it will be noticeable.
 
In still mode, set you exposure, press AE lock, which I set to just lock exposure, not focus and , yes, as pulpfiction007 mentioned, to stay locked after a touch of the button and then go to the live/video mode. Do this and there will be no flickering. Just remember to press the AE lock to release it when you change the shot or lighting.
