user516: In fact the question is the other way round:
I shoot a HD video with my Nikon-D7000, and along the way things happen, such as I change zoom, focal length, light levels change such that the D7000 adjusts its sensitivity during the recording...
Is all this data available for reading somewhere, and if yes how?
I could not find the information on regular websites (Nikon's, www.imaging-resource.com, general google search).
I tried exiftool, but it seems to only show general metadata that is true for the overall video recording.
So is this data recorded somewhere, and can I read it on my Linux system?
Any answer or hint appreciated.

user-1: No. Standard video formats do not work like that and the D7000 is no exception to this.  Conceivably it can be done but I am sure it is not on anyone's priority list. I worked for 9 years on video processing and rendering software and there are more important problems to solve. Indexing and managing that data would also become a problem. When working on functions that process video from a series of still images, it makes it vastly simpler to assume the metadata of the first frame applies to all subsequent ones.
Obviously I understand why it would be desirable but this is the same on all cameras. GPS is another perfect example. On cameras with built-in GPS, only the location of at the time video recording starts is recorded while you may be shooting from a moving vehicle and cover some ground while recording.
