Did Pulldown Change Progressive to Interlaced?

[Letricheur]

I captured Pal DV into Premiere, deinterlaced with decomb FieldDeinterlace() and converted to 24 frames per second (decimate [25]) in avisynth, and converted to MPEG2 with CCE 2.64 choosing progressive frames. Birate says this m2v file is progressive. After I run pulldown on it to make it 29.97, Bitrate says it is interlaced! Running it through DVD2AVI, the stats window flashes rapidly between progressive and interlaced and when finished seems to conclude that it is progressive.

How can I tell for sure whether it is still progressive after pulldown? I can't imagine that pulldown changed it.

Doh! The purpose of pulldown: change 23.976p to 29.97i

You are Telecining your content. Frames that appear progressive will be adjacent to frames that appear interlaced. www.doom9.org/synch.htm

Ouch!! Well, sorry to be so ignorant. Thank you for the information and next time I'll post my inquiry in the unbelievably stupid question from a newbie forum. Where is that again?

After pulldown you will get interlaced video, it's sure.
Reason for it is way how it works. Repeating each fourth field (half frame, each second line) will cause it. Actually some frames are combined from second field of first, and first field from second frame, and it is of course interlaced.
