No, slowing the shutter speed does not cause your image to stutter (neither does increasing the shutter speed). Instead, slowing the shutter speed will create more motion blur because the image sensor remains sensitive to the light for a longer period of time. So if the HFS100 had a maximum shutter speed of 1/6, and the HFS200 has a maximum shutter speed of 1/2, all they’re telling you is the HFS200 is capable of shooting at a slower shutter speed. That’s all. It’s just plain irrelevant when determining 24p capability. Make sense?
Your source is correct in saying that the shutter speed should generally be twice as fast as the frame rate, though, unless you have a reason for changing it.
I’m not sure what else to tell you, though. B&H seems pretty clear – one mode is Native 24p and the other mode is 24p with pulldown. Isn’t that what you wanted to know? What unanswered questions are you left with?
