Are the JVC cameras recording at a true 24fps or at 23.976 fps.
To explain what I am talking about, here is a chart about the differences:

23.976 (aka 23.98)
All 24P video formats that use 60Hz (59.94fps or 29.97fps) as their base will actually be 23.976 in a pulldown. This includes film to tape telecine transfers. The exception is a PsF systems like HDCAM which can actually clock itself to exactly 48Hz if needed, but it would still need to playback at 23.976 for DVD or broadcast, just like film transferred to video.

It's true 24p if you're set at 50Hz right?

You can't shoot 24P in 50Hz mode... only 25P, but 25 is 25 and 50 is 50.

But 30P is true 30P and not 29.97?

No, it's 29.97.
Keep in mind guys that "true" in this case is pretty meaningless. The fractional differences in speed exist so you can work within the digital video world without having to worry about losing sync with all manner of other devices.
It's a good thing, not a bad thing.
The only devices in the world that are locked to only 24.00fps are film projectors.

I'm so tired of hearing "true" tacked onto everything lately.
It begins to make everything meaningless unless its also true.

But I can understand the question. Some NLE's will literally cut 24fps or 23.98 video. Let's say you're working with a "true" (sorry) 24fps targa frame sequence.
