Need help to clean this "terrible" DVD source.

[maximo]

Hi all, this is my first post on this forum... sorry for my bad english.

I am trying to convert my DVD collection to mkv file whit x264 codec... whit LoRd_MuldeR's "Simple x264 Launcher".

Vob sample:

Source 1 - http://www.mediafire.com/?876b6fu25ftew3b
Source 2 - http://www.mediafire.com/?ef24me0ef62z4ma

How to clean this source from grain? blocking? noise? (especially in black or blue area of the video frame)... I don't know how to call this imperfection!!!

If I'm not wrong, the source is TFF Interlaced... I have tried to go progressive and denoise with this avs code:

AssumeTFF()
QTGMC( Preset="Medium", EZDenoise=3.0, NoisePreset="Fast" )
SelectEven()

This is the (poor) output... banding? haloing? ringing? (especially in black or blue area of the video frame)... I don't know how to call this imperfection!!!

Output 1 - http://www.mediafire.com/?kfxcchhyq72bxv8
Output 2 - http://www.mediafire.com/?s2upjcjeg33vu9p

Someone can help me?

Someone can suggest to me a script that I can try?

Thanks, maximo.

Strange video.

On the first VOB, when I bob it to 50fps using Yadif and step through, every 4th frame is duped. Basically it's frame,frame,frame,dupe,frame,frame,frame,dupe.

Is this a fieldblended NTSC 2 PAL video?

I don't know this... on DVD cover I read PAL.

However, the main problem for me is how to clean this source.

Any suggestion?

Thanks, maximo.

There's two separate issues.

The "blocking issue" which you report, is simply caused by the denoising. 8-bit YV12 is quite prone to show "banding" (that's the term for this). In the source, you can't see it because of the noise. After you remove the noise, you see ..... the banding.

Moreover, yes it's a NTSC>>PAL normconversion. Seems like 24p has been blend-interpolated to 48p, and this was convertet to 50i via field repeats. Theoretically this could be resolved with an appropriate SelectEvery(...) command after field separation, but that's very likely to run out-of-phase and require much manual correction.
I'd give a try on Srestore for this, it should do the job nicely.

Please, can you post me an avs script that remove this "banding" definitively?

yes it's a NTSC>>PAL normconversion.

Whit the QTGMC avs script that I've posted in the first post, I have not converted correctly to a "progressive output" the "TFF interlaced source"?

Thanks, maximo.
