How can 1080i be recorded in 24p?

[Armaxle]

The HVX200 has a setting for 1080i/24p. But if the data stream coming into the camera is interlaced, how can it be recorded progressively?

If anyone can shine some light on this apparent paradox, it would be much appreciated.

It's not. It's progressive footage being recorded as interlaced, using pulldown, just like the DVX does with 480i DV. (And just like the HVX does with 480i DV, for that matter.)

For information on pulldown, see:
