Please somebody help me figure out what is going on with this clip there appear to be dropped and duplicated frames. Is there any way to restore smooth movement?
Thanks.

This is the state of the DVD release, OK it is public domain material but why treat it like this?

Yes there do seem to be duplicate frames. I'm guessing it's because of the decimation process. What did you use for your script?

What is the title and region of the DVD? Is that a direct rip? If not, how did you encode it?

It is an Australian release of "One step beyond". It states that it is region free. The video is PAL but I wonder if it has been converted from NTSC by some very dirty process.
The series has fallen into public domain and there are several different versions about, varying in quality, but all poor.

The clip that I posted is simply a few seconds of the vob cut out using womble mpg-vcr with no re-encoding.

Thanks for the help...

The duplicates you could decimate, but there are missing frames as well, so it's a lost cause IMHO.

Thanks. Pretty much what I thought but its best to ask those who know about these things...

The mvtools2 docs give this example for interpolating bad frames:
AVISource("c:\test.avi") # or MPEG2Source, DirectShowSource, some previous filter, etc
super = MSuper()
backward_vectors = MAnalyse(super, isb = true, delta=2)
forward_vectors = MAnalyse(super, isb = false, delta=2)
inter = MFlowInter(super, backward_vectors, forward_vectors, time=50, ml=70)
# Assume bad frames are 50 and 60
trim(0,49) ++ inter.trim(49,-1) \
++ trim(51,59) ++ inter.trim(59,-1) ++ trim(61,0)


MFlow can give really funky results, though. So it may look bad if you're missing a lot of frames. Might be worth a try.
