PAL Interlaced

[tengo6dedos]

Hello, can someone help me with this source, is in very bad state. Is a anime PAL and i have no idea what to do with it, is possible to fix this?

sample



thanks and saluts

It's field blended. Look at the deblending filters.

[tengo6dedos]

Thanks, ive tried Telecide but it has so many blended frames that maybe is pointless?

The other way would be like a FieldDeinterlace().Tdeint(tryweave=true) but still ends very bad.

On top all guides are in english and i dont know it very well.

Is the original source also NTSC ?

[thewebchat]

You need to use SRestore, not Telecide or some other IVTC (because it is not telecined).

[tengo6dedos]

So also a bob before Srestore? something like

YADIF(mode=1, order=1)
#edi=NNEDI(field=-2)
#YADIFMod(mode=1, edeint=edi)
SRestore(FRate=25)


Is this the way to handdle this? What others tweaks may i do, the blending will never disappear completly right?

Also Is there a problem if i use mt on the script, setmemorymax(512).setmtmode(2,0)?



thanks

Whether the blended fields will ever completely disappear is dependent on how many/what kind of conversions the original film stock went through before it reached the DVD. For single conversions, there is no theoretical reason why the blending couldn't be removed, but SRestore will probably not detect them all, especially in parts with lower motion. For any other type of conversion, there is no hope of removing the blending completely. Also, you can't use MT on decimation filters. That's just Not A Good Idea (TM). You could use MT on the deinterlacer though.

Thanks for the info, so i guess this is on the "other conversion" cathegory because even after the lines i put back in #5 the film keep having lots of ghosts/blends on high motion scene, is there a tweak for srestore or other line advice you can give me to try hit more blends on my source?

[thewebchat]

The only "tweak" I know of is to decimate the blends by hand using Yatta or similar. If you can find a cyclic pattern, this shouldn't be too bad, but if you can't, now's a good time to give up.

The only proper solution is of course to buy the NTSC DVD since PAL is garbage.

[manono]

That one won't ever completely unblend as there are just too many blended fields to begin with. However, you can improve things a little bit by getting the framerate correct. You'll get your best results when using the right framerate, and it's not 25fps. It was converted from NTSC film, so a better choice would probably be SRestore at default settings (and framerate).

And as thewebchat said, if you really like this series, get an NTSC version.

[tengo6dedos]

Thanks all for the help, one last thing, can you tell me how to know when the first source is NTSC?

[neuron2]

For NTSC DVD, frame rate = 29.97.

[tengo6dedos]

Sorry i ment how to know when you have a PAL dvd thats been bad converted from NTSC and is not just interlaced, fieldblending PAL always means that?

[neuron2]

always Can't commit to that, but "usually" would be good. :)

[tengo6dedos]

Can't commit to that, but "usually" would be good. :)
je yes always seems to be very rare here


Also, you can't use MT on decimation filters. That's just Not A Good Idea (TM). You could use MT on the deinterlacer though.

So where should i put the setmtmode line in this script?

edi=NNEDI2(field=-2)
YADIFMod(mode=1, edeint=edi)
SRestore()

[Didée]

Nowhere. NNEDI2 is already multi-threaded internally, speedy Yadif doesn't need it, and SRestore should/must not be multithreaded for technical reasons.
