Progressive or Interlace?

Can someone please make this clear to me?

From the manual (Vol2):

30P mode:
Shoot 30 frames a second in the progressive mode. For output and recording, the 30-frame-per- second signal is converted to 60-field-per-second interlace.
This mode gives you high quality images.

24P mode:
Shoot 24 frames a second in the progressive mode. The video signal will be recorded natively. However, the external output signal is converted to a 2:3 format, 60 fps interlaced signal

If in 30P, you will get interlace in camera (to card) plus out to HDMI/SDI and in 24P you'll get Progressive in camera (on card) and interlace out to HDMI/SDI. Am I correct?

If this is correct, then using a nanoflash with all its bit rate will be... interlace? Or is there a way around that? Or am I wrong about the whole thing?
 
As far as I know. All footage record in camera to card is progressive. All HD-SDI is interlaced and your recorder can make it progressive.
 
Going to the SD card , you can get 1080x60i .. the rest of the modes are progressive.
Out the HD-SDI, it's 1080x60i unless you've got the 24PsF option on .. and then it's progressive.
Lots of things turn off when you go 24PsF (HDMI, VFR, etc.).

Your SDI recorder should be able to happily slurp up 60i and convert it to whatever
internal recording formats it supports.

Has anyone compared the resolution interlaced vs. progressive? could it make sense to shoot 60i for that matter!?
 
Interlace is the original compression artifact. I hate on it. I have hours of Underwater footage from a recent project that is 1080 I recorded from the ROV camera and the interlace artifacts are downright awful in places.
