Hybrid NTSC -> PAL conversion script...

For shows that were shot on film, then telecined, then edited in NTSC, clean conversion to PAL is... well, a compromise between different ways of screwing it up. However, I've been thinking of what might be the least bad way to do it, and this is what I've come up with:

Code:
mpeg2source("106.d2v")

loadcplugin("c:\yadif.dll")

A=yadif(mode=1).selecteven()
B=yadif(mode=1).selectodd()
C=Tfm(field=1,mode=0,slow=2,cthresh=2,mthresh=2,clip2=A,micmatching=0)
D=Tfm(field=0,mode=0,slow=2,cthresh=2,mthresh=2,clip2=B,micmatching=0)
Interleave(C,D)

tdecimate(mode=1,cycle=6).spline144resize(720,576).separatefields().selectevery(4,0,3).weave().assumefps(25)
Obviously, it starts out as my boilerplate "field-match what you can, bob the rest" script. You can replace all that with QTGMC or whatever else you want. Did I do a good job overall?

EDIT: added assumefps

If the hybrid source is 29.97 fps the script delivers 24.975 fps. You may want to speed it up to 25 fps for PAL compliance.

SRestore aims primarily at unblending field blended crap due to poor framerate conversions. The result is progressive video.
From the heading ("Hybrid") I assume that her source is rather a mix of true interlaced video and telecined video with perhaps broken telecine pattern and orphaned fields. Her script with reinterlacing may preserve the temporal resolution of the video part.
Just speculating.....

Yeah, I realized that a little while after I posted. Didn't get around to correcting it until now. Thanks. Anything else?

Yes, exactly. Stuff that was shot on film or digitally at 24 frames per second, then telecined, then edited in a natively interlaced medium with 60z effects and crap added.
