I suppose you wanted to reply to my comment...
I don't know why those people use field coding for interlaced H.264 in
HD-camcorders, but the fact is, they do. I've checked with Panasonic,
Canon and Sony camcorders. They all seem to produce field-coded
interlaced movies (i.e., each frame is coded as two separate field
pictures).
My Panasonic camcorder can also record in 25p cinema mode. In this case,
it produces frame-coded progressive movies (i.e., it uses frame picture
in H.264 instead of two field pictures per frame).
Anyway, since I want to use it, I'm going to fix it somehow. Just don't
know really how, since both solutions I thought about are not
particularly good.
Regards,
Ivan
