Determining Field Order

Okay, I'm trying to figure out whether a bit of 29.97 Interlaced footage is Upper Field First or Lower Field First, and have no idea how to do it. If anyone has an answer, please let me know!

I honestly don't worry about it and just tell TFM to use order=-1, which relies on AviSynth determining it.

From the read-me:

order -

Sets the field order of the clip. The field order must be correctly set for
accurate field matching to occur. Possible values:

-1 = auto (use avisynth's internal parity value)
0 = bottom field first (bff)
1 = top field first (tff)

Default: -1 (int)

If I notice something's gone wrong I'll go and correct it, but sofar with TFM it's not been necessary.

Qyot27 .. a question along those same lines. I have, for quite some time, been trying to un-mux an interlacing problem with three DVD Series. They seem to have been originally encoded in PAL then MUXxed into 29.97
.. Through a DVD Player and my 36" TV they play-back "just-fine" ^_^
.. After ripping them, I find it impossible to reconstruct the interlacing for Editing.

.. I've gone as far as using PAL Smart Deinterlacing, frame serving thru a field splitter, re-timing the PAL and then using a standard Field-BOB to do final Deinterlacing. This works on 98.7% of the frames but, any movement to the right -or- left looks like a jig-saw-puzzle T_T

.. I'm most likely doing this wrong; I've been at it for over three years X_X .. what's going on here?!?

I have no idea - I don't have any of those discs and the only tangible example of bad interlacing/telecining I have is Ranma ½, which I haven't used since long before I switched to TFM.
