OK, will try that.

I have an antrociously poor quality source, grey-washed, interlaced:

Lord of filters, what can be done with this? :watchingyou:

elguaxo

upload a sample! :beerchug:

spudthedestroyer

grrr... you with your samples :wacky:

i doubt it will do any good... but here's a snippet:
VTS_01_1.VOB (38m)

DxaKrator

Heh...when you are done with that one I got a couple you can look at :twisted:

....fucking horrible...If you can fix these then you are indeed a guru :lol:

elguaxo

well... I don't see problems with the interlacing! what filters are you using?

Code:

DGDecode_mpeg2source("I:\videos\spud\VTS_01_1.d2v")

Interp = nnedi(field=1)
TDeint(order=1,field=1,type=1,cthresh=5,chroma=true,edeint=Interp,emask=TMM(order=1,field=1))
Vinverse()

crop( 2, 94, -2, -116)
Spline36Resize(672,288)

TDeint & TMM: http://forum.doom9.org/showthread.php?t=82264
Vinverse: http://omploader.org/vbTh5/vinverse.7z

If you see interlacing artifacts at some other part of the video, then post a sample that includes that part.

and then maybe something like this will help you a bit with the macroblocks/mosquito noise and all the other crap:

Code:

DGDecode_mpeg2source("I:\videos\spud\VTS_01_1.d2v")

Interp = nnedi(field=1)
TDeint(order=1,field=1,type=1,cthresh=5,chroma=true,edeint=Interp,emask=TMM(order=1,field=1))
Vinverse()

crop( 2, 94, -2, -116)
Spline36Resize(672,288)

source = last
deblocked = Deblock()
backward_vec2 = MVAnalyse(deblocked, isb=true, delta=2, pel=2, overlap=4, sharp=2, idx=1, truemotion=true)
backward_vec1 = MVAnalyse(deblocked, isb=true, delta=1, pel=2, overlap=4, sharp=2, idx=1, truemotion=true)
forward_vec1 = MVAnalyse(deblocked, isb=false, delta=1, pel=2, overlap=4, sharp=2, idx=1, truemotion=true)
forward_vec2 = MVAnalyse(deblocked, isb=false, delta=2, pel=2, overlap=4, sharp=2, idx=1, truemotion=true)
mask = mvmask(kind=1, vectors=forward_vec1).UtoY().Spline36Resize(672,288)
smooth = source.degrainmedian(mode=3).fft3dfilter(bw=16, bh=16, bt=3, sigma=4, plane=0)
source2 = maskedmerge(source, smooth, mask)
MVDegrain2(source2, backward_vec1,forward_vec1,backward_vec2,forward_vec2,thSAD=300,idx=2)

Its not the deinterlacing so much as how atrocious it looks, its just NTSC and interlaced because of the way it was translated and i think it fairly straight forward to zap.... however the gray levels, the fussy moving edges, etc.. i'll try your filter set and see how it goes although there doesn't look to be much improvement and i doubt you can do anything.

methinks a lot more processing maybe needed :lol:

color/gray levels may be easy to improve, at least a bit with Levels and/or Teak, but a lot of manual tweaking will be required. I recommend you AvsP so you can see the results in realtime.

The moving edges... that sounds VERY hard. My script deals only with the huge macroblocks and ringing.

fuEgo

I got a demuxed ac3 (via DGIndex) that has a delay of 88526ms. First time I experience that.

In VirtualDubMod I set Audio Skew Correction to 885ms and Preload to 96ms and Interleave 96ms... that seems to work, but I get this info with GSpot:

Interleave.............: 96
Preload................: 32
Audio Alignment........: Split

Why isn't Preload 96ms then...?

-----
Another question is about vobsub, they are also out of sync about ~ 00:01:43... very weird.
I've tried offset with VobSub Configure with no luck. Also edit the .idx file with notepad, but don't know how...?

elguaxo

Weird Interleave/Preload: I got this twice, one time it was a b0rked AC3 track. FFDShow Audio had no problems handling it, but everything else did. The second time I don't know what happened but playback was absolutely fine. I tried every software and Standalone I could and everything was fine. So it's not necessary a bad thing. Anyone else some experience with this?

Delay for subs. It happens a lot. Insert somewhere at the beginning of the IDX file:

Code:

delay: hh:mm:ss:ms

(replace hh:mm:ss:ms by your delay)

fuEgo

Thank you elguaxo.

But it don't work or I'm doing something wrong...

Quote:

# To repair desyncronization, you can insert gaps this way:
# (it usually happens after vob id changes)
#
# delay: [sign]hh:mm:ss:ms
#
# Where:
# [sign]: +, - (optional)
# hh: hours (0 <= hh)
# mm/ss: minutes/seconds (0 <= mm/ss <= 59)
# ms: milliseconds (0 <= ms <= 999)
#
# Note: You can't position a sub before the previous with a negative value.
#
# You can also modify timestamps or delete a few subs you don't like.
# Just make sure they stay in increasing order.

delay: [-]00:01:43:000

I've also tried without the [].

Tried this, but the encoding got stuck twice. It only completed one pass and didn't even make an avi (only the fake one without sound). Here's the log:

@fuEgo: I checked and you must place the delay above the first timestamp line for each language stream. Read more here: http://forum.doom9.org/showthread.php?t=38955

What about Heini doing only one pass? Thanks in advance for any useful remarks.

I'm experimenting with SubResync now, it's a little better but some of the languages behave differently, even with the same time codes...hmm?

Edit:

@slayer --> can you please edit the very long line in your log, thanks.

Done.

Which do you prefer, guys...?

or

elchupacabra

The second.

RedVeil

Can't tell it without seeing the actual resulting image. The cropping is different in these two settings. Could it result in overcropping or undercropping?
I don't like Zoom ratios above 100%, because that means the image is unnecessarily stretched horizontally or vertically. Aspect error should be as low as possible - so the second settings win that round though.

fuEgo

THX, I'm beginning to learn that AR and zoom is more important than the infamous 720 resolution.

A new movie was driving me crazy, regarding correct AR... see pics.

VOB

xvid

Here I thought, that a telescope sight is completely round... I guess my test encode is okay then.
Please comment.
