Determining Field Order

Postby SrgtWilco » Mon Sep 17, 2007 11:02 pm

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!
Murphy's Constant: If outcome may = A or B, where A=Good and B=FUBAR, anticipate B as most probable result.

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.
