Filming with the D7000 / exposure time / LO Setting
Heyo, i have kind of a technical problem.
For various reasons i only film in M(anual) mode (since i do not want the camera to interfere by adjusting lights / etc.).
Within this mode i can only go down to a exposure time of 30 - apparently because that is logically the minimal needed fps for HD film.
In night situations this can be quite dark. However - when i select AUTO mode it switches to "LO" in dark situations.
Is there any way I could select that in Manual Mode?

"Lo" is not a mode or shutter speed. It is just the camera telling you that it is really dark where you are taking movies/stills. The camera is still picking one of the existing exposure settings, but not telling you which one while it says "lo".

You will not have as much flexibility for setting random shutter speed in video...you can but the images will suffer. A rule of thumb is to set a shutter speed twice as fast as the reciprocal of the frame rate so if you are shooting 24fps, 1/24 divided by 2 is 1/48 and the closest to that number is 1/50 which you can set. Setting is lower will blur movement and setting it faster will result in less smooth movement.
The 3 variables you control exposure with are lighting, ISO and Aperture when shooting video. Higher ISO adds noise and wider apertures make the DOF narrower. So which of the 3 or which are used in combination is where exposure for a scene become more of an art than technology since each element has artistic influences on the results and it is up to the videographer to decide how they want the scene to appear.
If you have seen a movie set during shooting, you probably saw a lot of attention to lighting and lots of equipment to control the light. This is because they are selecting light the way we still shooters select shutter speed...to give the desired exposure for the aperture desired(DOF).
