24 frame judder

I'm aware of the risks posed with excessive motion when shooting 24 frame images. I just shot a commercial where the client asked for some moderately quick pans and tilts. It all looked smooth in the monitor while shooting, but when we got to post there was quite a bit of "stepping" on those moves.

Two questions: can anything be done about it now, post-wise? And in the future, how do I get around this if I want the film look of 24 fps and quicker camera moves? Do I settle for 30fps?
