Anyway, thanks for pointing that out. Removing QTGMC will boost the encoding speed by a lot.
24p film is converted to 25p PAL by speeding the film up 4% so each film frame becomes one PAL frame. Nothing like the 3:2 telecine NTSC countries have been cursed with.

So, the broadcast was probably interlaced, and the bitstream is probably flagged as such. But the actual frames themselves are progressive source, and with MBAFF are made entirely of progressive macroblocks.
