iirc the directors cut has additional scenes that are of poorer quality... most of the film looks great... except those

I've never seen the cut version so couldnt guess if this is one of those scenes... I only checked the start of vob1 so I'll check a bit further along & see if its still present :)

Sucks though... whole thing should be prefect for an awesome film like this. :matrix:

Post subject:  Re: Filtering Help Required Please
I'm wondering if theres a way to clean these scenes up though? There cant be many of them & I suspect that they'll all be the same quality & with zone options I can switch the filters at each point in the film.
Wonder where to ask? Lux is AWOL atm so need to venture further afield :wacky:

You could try RemoveNoiseMC with LQ or MQ_Filter. Seems to clean up muddy VHS sources reasonably well.

Post subject:  Re: Filtering Help Required Please
Thanks for the tip Visceral, unfortunately I've not tried either of those filters before (I've not tried very many in fact).
Do you have any links to the filters or sample activation scripts? or even cheekier, could you post a sample script I could try?

Thanks :D

Obviously that's using mq_filter, you can comment/uncomment out as necessary. Also check out AvsP for real time comparisions of filtering

Post subject:  Re: Filtering Help Required Please
you'd want to split by frames too, so you are only applying the noise filter/cleanup filter to the required segments of the movie.

Hey. Could you elaborate on how that is done? I already asked this over here http://forum.dead-donkey.com/viewtopic.php?f=2&t=16962 and nobody told me. :evil:

i'm not quite sure elchupacabra, i don't know where the framesizes would come into it on that particular script.

Thanks for the script Visceral :mrgreen:
Unfortunately it didnt help so I'm gonna stop worrying about that for the timebeing as I have a more serious one...

I've cut a cleaner section from the source & tried all the basic deinterlacing options for it & they all produce the same result...
Stuttering.

Using this code created a 50fps rip that ran smooth:
LoadPlugin("C:\PROGRA~2\GORDIA~1\DGMPGDec\DGDecode.dll")

#  SOURCE
mpeg2source("F:\GK CRAP\split.d2v")

assumetff().separatefields()


I'm not sure what a blended field is but I'm guessing it means this (Cap from the 50fps clip):
Image

Doing some research I tried a few things with decomb.dll that are suggested in the documentation. This is the recommended one if I read it right:
LoadPlugin("C:\PROGRA~2\GORDIA~1\DGMPGDec\DGDecode.dll")
LoadPlugin("C:\PROGRA~2\GORDIA~1\AviSynthPlugins\decomb.dll")

#  SOURCE
mpeg2source("F:\The Wicker Man\GK CRAP\split2.d2v")

#  DEINTERLACING (3) - special requests
AssumeTFF()
Telecide(blend=true)

#  CROPPING
crop(16,14,688,548)

#  RESIZING
spline36resize(704,384)


This doesn't help. Its more like a slideshow during movement. Can anyone suggest a filter for this please?

I'm about ready to give up on this :voodoo:

You have blended fields from a standards conversion.
You'll get better support at Doom9 for this. I have zero interest in recovering field-blended garbage.

Nice bloke. :prat:

Do you get blended fields if you don't convert to 50fps? I found that fucks things up in circumstances like this. You'd need to use a better deinterlacer that doesn't blend.

Post subject:  Re: Filtering Help Required Please
I'm not entirely sure what you mean spud :?

The vob sample above (http://www.mediafire.com/?cfztnor5yey) is uncompressed, only 6.87mb & 10secs long.

This is what neuron2 came to his conclusion with.

Could you have a go at it please? I'm new to this filtering & like with every other rip I've done, theres been something new to fix although this one has hit a brick wall. I've kept logs of all other filters that I've used or been suggested to me so I can go back & try them on future rips with similar problems.
I could easily just rip it as an AFR but the end result would be crap & being a perfectionist I'd rather not do it unless I can get it as good as possible. :suicide:
I've got a compression of 88.3% with SoulhuntersV8 with no filtering at 1.44GB so this could be good if you or anyone can help fix this stuttering. :watchingyou:

Thanks :D

check the Ripping/encoding/releasing Q & A thread at SBiG, there are tons of samples how to deal with field-blends:

fieldblends don't have anything to do with deinterlacing

erm, yes it does, if your source isn't blended and your outcome is, it can very well be your deinterlacing method... run any deinterlacer with "average", "blend" or "combine" in its title; that is a field blend operation to return a progressive frame.

Examples a plenty:
