An actor should be able to repeat the same action, over and over and over again.
With something like a cigarette, yes, but there is always some discontinuity. Rusty's hand motions screwed continuity (on wide shots) and I had experienced actors. In fact, you've probably seen my actor, Rusty Meyers, in movies like SILVERADO (Rosanna Arquette's husband) and Wendy's commercials like this one:

Another thing, I suggest is the "Cutaway." An example would be a shot of the bartender or ex-wife watching the couple. If the continuity was something I was having trouble with, I can cut to a cutaway, at that point. A cutaway can be a dog, cat, bird or anything else near the conversation or action.
So this leads me into my next question, how do I get these multi-shot sequences with one camera in an action sequence when someone is running or jumping? Then do I have to film from different angles multiple times?
Does it look professional for a camera to be moving or zooming at all?
Again, I use one camera for action shots. I don't make people fall down too many times, but the key is to get "overlapping action," so you can cut it together. Yes, you get a running angle from the front and from the back.
I suggest you write down or storyboard what shots you need, before going out on location. I try not to do multiple angles of the same action, as much as overlapping shot A into a further point that begins shot B.
In today's movies, people don't need to see every single second of movement. For example, a cop is at home and he gets a phone call about a crime. Do you need to show picking up the phone, putting it down, walking to the door, closing it, getting into his car, starting it and driving it away? No. This can be done in two shots:
1) Phone rings, cop pulls out his cell and looks toward the door or exit.
2) His car starts and speeds away.
If you've seen the car in previous shots, it's no problem. If not, be sure you can see him in the driver seat, and it pulls away.
There's a chase in my short,
THREE STRIPE. Start around the 3:45 mark.
Another chase in
ROADKILL. Start at the 5:45 mark.
When deciding what shots to use, think of whose Point Of View you are trying to emphasize. In the ROADKILL clip, Devon starts running, as we track with him from the side. Then, we track with the faster Camaro, as it enters the shot. As the Camaro closes in with Claire aiming the gun, I want to have her point of view (aiming) - tracking in closer, from behind Devon.
Once you decide on who would be seeing what, you can visualize the scene.
Zooms used often come off as "video-ish." Most movies use dolly in and out shots, like when 2 guys are at a standoff. Of course, you can zoom in, but cut it like a movie. Don't hold the shot for the whole zoom. Zoom into one guy for a second or two, then cut to the zoom of the other guy. (The motion should be in the editing, as you mix in closeups of gunholsters, people scattering, etc.) You can also try whip zooms, where the action is very fast. (I usually speed this up, in editing -speed ramp - so I don't have to jerk the camera doing it.)
