Hey,

I've recently tried to backup an interlaced PAL movie (25 fps), but failed to do so.

I'm usually dealing with PAL material where no decimation or alike is needed, but don't know how to rip this movie.

For ripping I'm using MeGUI which identified the video as partially interlaced (automatic analysis). It then chose Yadif to do the deinterlacing.

The resulting video was indeed deinterlaced but was also jerky. Upon close inspection I saw that the resulting video has duplicate frames. Frames 1-22 were OK, the 23rd was a duplicate of 22, 24 OK, 25 a duplicate of 24. Don't know if this pattern repeats itselft throughout the movie, though.

How would I go about ripping this video ?

I've uploaded the sample here (http://www.mediafire.com/?sharekey=8f834c0c167fccaf07258ee67c679e4ac2219701373f5373ce018c8114394287).

The AVS script that MeGUI produced is the following...
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\VSFilter.dll")
DGDecode_mpeg2source("D:\!devils_pond\OUTPUT\devils_pond.d2v", info=3)
ColorMatrix(hints=true, interlaced=true, threads=0)
Load_Stdcall_Plugin("C:\Program Files\megui\tools\yadif\yadif.dll")
Yadif(order=1)
LanczosResize(720,576) # Lanczos (Sharp)

Any help would be greatly appriceated.

tdeint(mode=1) #or yadif
tdecimate(rate=23.976,mode=7)

This seems to work.

hmm, still doesn't look smooth to me :(

DGDecode_mpeg2source("sample_d.d2v")
tdeint(mode=1) #or yadif
tdecimate(rate=23.976,mode=7)

The stream has missing frames. You'll never make it smooth unless you interpolate the missing frames.

Thanks for looking into this, neuron2!

I'm guessing there's no easy way of doing what you suggested, right? :(
