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.
