I am asking these questions for a friend who uses the D800 for topside photo work. He has not shot video with it and was asked to shoot video in a somewhat dark club. After speaking to him, and not knowing the camera myself, I had some questions for the audio. I can lend him a shotgun mic and use the 1/8 in plug but do not know whether the D800 allows for or has any metering for the audio levels. He also wasn't sure what ISO he should use and I suggested that 800 or 1000 might be the best chance for getting a clean shoot but I very well could be wrong on this.
I did download the Nikon manual and did a very quick scan of the index but saw nothing. Also assuming that the D 800 will shoot video in both 1080p as well as 720p. He doesn't know and neither do I.
Anyone have any answers for this? Suggestions would be appreciated.
