The minimum crew
The minimum crew
At the very minimum you are going to need to following for shooting a short film on DV:
A camera operator to run the camera.
A boom operator to run the boom which should be plugged into your camera.
Two grips to move and set up the lighting for each set up.
Two PAs, one serving as a general assistant to the grips, the other serving as a general assistant to the camera op and boom op.
Now, if you don't know much about lighting you will also want to have a DP or lighting designer on set. A good script supervisor is worth their weight in gold, as is a good AD. Also, if you are filmming in several locations, working with a ton of props or extras, or have special requirements for shooting I would also suggest a UPM.
