It feels to me as if 24p has a slower shutter speed (ie more motion blur). If I were filming a movie that required more camera movement (like following a rollerblader down a hill), could I get away with the 30p setting? The goal is still to look like film, but 30p looks like it has a fast shutter speed which would be easier to use with fast moving shots.

One more thing on the piano... did you do the reverse telecine or is that just straight from the HV30?

In the electronic world 30p is easier to deal with. But me, I like messing with 24p. Remember that all action movies are shot in 24p and seem to cope well enough with fast action.

The piano clip above was shot in 24p and then reverse-telecined.

Shutter speed and frame rate are not the same thing. You could shoot at 24p and have the shutter open for only 1/1000s. Or you could shoot at 30p and have the shutter open for the whole 1/30s.

The most movie-like footage seems to occur when the shutter is open for half of the frame duration. So at 24fps the shutter should be 1/48s.

There are various tricks to get the HV20 to into an optimal filmlike mode.
