Choppy footage of fast moving subjects

I have found that I am getting choppy footage for fast moving subjects. I tried changing the shutter speed, frame rate (in the scene file), and rec format. I have tried various combinations, and the one I've settled on is 1/24, 1/24, and 720/24PN. It makes sense to me, and seems to look as good as any other combination. Is this the best way to get smooth footage in 24P?
 
If you want smooth video, shot 60i
Barry DVD shows how 24P works.
Post a clip, so we can check your "choppy" footage

I was speaking with a post production person today, and it looks like I was just panning too fast. He stated that everything, including 35mm film, would give me a bit of choppiness when you move the camera too fast. Does this make sense?
 
Correct. Filmmakers figured this out shortly after film was invented, and made a chart of how fast a pan could be made. But that was at 24fps. Go to 30 and you can pan faster, at 60 even faster. But you start losing the look of film.
 
Barry's book gives exact information for pan times necessary to avoid choppiness in various formats. The more of a film look that you try for, (i.e. shooting in 24p) the slower you have to pan. There's just no getting around it. Keeping a moving subject as the focal point while panning will draw attention away from background chop but it's still there. Look for it in films and you'll start to pick up on it and be able to decide what is acceptable for your application.
 
I got the book. Wow, my question is answered right there in the first few pages...

Now, what about using 350degrees shutter with 24P. You get a nicer blur, but I suppose that is not really a 'film look'. I actually prefer it.
