I've been reading a lot about how different cameras implement their version of 24 frames per second.

And I've come across some suprising comments:

The Canon HV-20's 24p may actually look more natural than the XH-A1's 24F.

The Panasonic HVX200's 24p has less resolution than its competition.

Sony's CineFrame 24p-like implementation of decreases resolution considerably.

So what do you think? Which camera do feel does 24 frames per second the best?

Don't go for Sony's Cineframe, it's very bad bad bad. It doesn't look like 24p at all.
I think the 24p mode on their VU1 is sufficient, but I don't know for sure.

The HVX has lower resolution chips, but uses pixel shifting to get to HD resolution (I don't know the technical details about pixel shifting).
Some people say you really can see the resolution difference, others say the complete picture looks fine enough.

The JVC should have a good 24p option.

I think the CAnon's have the highest resolution 24p, but of course it's 24f, although most people seem to agree you can't see the difference between 24f and 24p.
