storyboard

I'm not sure if this is the right board to ask, if not just tell me.

I have never done animation before, I'm used to ''real'' movies, where my poor drawing skill isn't that much important since details (like how much steps a person do in a scene) can be overlook, and the camera angle is the most important thing (mostly). But I'm trying to do a storyboard for a short test movie and I'm asking myself how much details people usual put in such board.

I'm sorry I'm rambling again but I'm not English and I just can't ask right away what I want to know. Let me try again.

If you use 15 frames/sec, will your draw every frames or just the start and the end of the scene, like I usually do in a ''normal'' movie?

I hope you understood... :? Thanks! 8-)
