Does Pal SDVD Need TDecimate ?

[Jeremy Duncan]

I wrote a walkthrough for how to use FFDshow.

This is the configuration that's causing Pal DVD users problems, they say it stutters on SDVD-pal, SDVD-NTSC works fine for me.

SetMemoryMax(1024)
tfm(order=1,chroma=false)
tdecimate(chroma=false)
FluxSmoothT(3)
ColorMatrix(Mode="Rec.601->Rec.709",clamp=false,threads=2)
MT("SeeSaw(NRlimit=0, NRlimit2=5, Sstr=2.22, Szp=1, Slimit=9, Sdamplo=16, Spower=1, sootheT=95, SdampHi=39)",3)
WarpSharp(depth=20, threshold=20)

I know in Decomb, Decimate isn't used for Pal.
But I don't know if TDecimate is the same.

:thanks:

When I change my refresh rate to 75 hertz, and use reclock to change my fps to 25, I get no stutter using tdecimate.
But when they do this, it stutters for them.

The times when you decimate PAL sources are extremely rare from the samples I've seen. 24->25 telecine just isn't done often, and if it is it'll be corrected by TDecimate(cycle=25), not the default. Almost all of the time it's sped up (or field-blended, natch), so there's no duplicates to remove.

I have no idea how you get no stutter when you're butchering a show that bad.

Thank you for showing me that.

Out of curiousity though, may I ask if Telecide(chroma=false) and apply pulldown are used by pal dvd's ?

[Jeremy Duncan]

I meen, can pal sdvd use telecide(chroma=false) ?

I googled if pal uses pulldown and found that only ntsc uses pulldown.

Testing this dvd, not this clip. But it's unprocessed source material.

Playing the dvd with mpc changes the filed order, so dgindex says it's tff, but mpc shows it to be bff. Tritical showed me this in my tfm thread: reply 8 (http://forum.doom9.org/showthread.php?t=129740)

This was my finding.
That without pulldown activated if ffdshow, telecide doesn't remove the combing/stairstepping seen in this clip: Link (http://www.megaupload.com/?d=GT6H5IJ4)

But,

The over canada clip with the whales, is affected is I use a field order and telecide(chroma=false).
If I set it to tff, it stutters pretty bad, but if I set it to bff it doesn't stutter noticably.

So telecide and tff() isn't only useful for ntsc.
Pal doesn't use pulldown, but it seems like t can use tff() and telecide to remove stutter.

d2v material (http://www.megaupload.com/?d=C12DHQJD)

The d2v I uploaded, if it's played using ffdshow and mpc using this code stutters pretty bad:

SetMemoryMax(1024)
AssumetFF()
telecide(chroma=false)

buffer back/ahead: 1, 15
Ignore pulldown selected since this dvd doesn't use pulldown.

However, if I use this code below, it does not stutter:

SetMemoryMax(1024)
AssumebFF()
telecide(chroma=false)

Telecide is not just for NTSC pulldown removal. It is a field matcher, so it's also useful for PAL clips with a one-field phase shift.
