Okay i went with TFM() as it worked well, donīt know why though;S
But wonder, i got a DVD source of a movie, and itīs shaking all the time, like it was VCR or something, but it isnīt of course.
So wonder, is there a way to prevent this, without damaging the picture. -
That's not a DVD source. Why give the much bigger Lagarith AVI when the VOB or (better yet) the M2V would be smaller in size? Anyway, the AviSynth filter Stab is designed for that kind of thing. DePan can stabilize it. The VDub filter DeShaker can also fix it.
http://avisynth.org/mediawiki/External_filters#Stabilization -
When people ask for samples or you provide samples without being asked, it's a sample from the source we want - from the DVD. Not an x264 reencode, not a lagarith reencode. Who knows what kinds of filtering has been done to it, intentional or not, that may cause it to differ in significant ways from the real source.
-
Take it easy, yeah i know but i currently donīt have it, will get it and sample it if i canīt work it out.
Thanks -
Thanks, well got another thing i want help with.
Itīs about cartoons having blended frames, and i wonder if i can delete and remake those?
As from VCR source it may make a better result, problem is making it the same.
Can show you an example, but canīt splitt the vob file, how do i do that?
Thanks -

SRestore()

http://forum.doom9.org/showthread.php?t=95924
It's not perfect, though, with that crappy source. -
This only Revert it back to the NTSC form right?
I wanted to remake the blended frames.
First remove them with srestore() maybe, them recreate them, as i think it will make it look better?
Thanks, itīs just a theory of mine though -
What is best if the volume is pretty low on a captured VHS, increase the line in volume. or increase the volume on the WAVE?
-
Increasing the line in volume with a good analog amp is preferable. But unless the volume is really low, you probably won't notice a difference.
-
Does the Volume Meter in VD mean anything, as i thought everyting over 0db is erased. But when i look at the wave file in the end, itīs not even near 0db;O

Is this TFF or BFF?
I think itīs TFF as itīs PAL, but there is a thing which makes me wonder.
There is a Fault line that appears in this clip. If i use QTGMC() with TFF it appears for Some frames. but with BFF It appears in One frame.
Anyone know why? -

Well "fault line" is the line that is black, i just call it that.
But why does it appear in one frame (which is acceptable, i mean 1 line per frame etc), normally and Deinterlaced BFF.
But it is delayed with TFF?
And how can you be sure itīs TFF or BFF?
Is it just, PAL or NTSC?
Canīt they fail on that, and make NTSC TFF as a bad convert from PAL or something?
Thanks -
Because QTGMC uses multiple fields/frames to piece together complete frames from individual fields. It doesn't know the black line isn't supposed to be there.
Apply a simple bob filter and step through the video. If you see jerky back and forth motions you have the wrong field order. For example:
Code:AviSource(...) AssumeTFF() Bob()
-
Okay will try the Bob thing out to see if i can understand it.
But is that good?
I mean, it sound like QTGMC my delay all kinds of stuff (though i havenīt seen any Bad stuff except the line and the Game Fail.) -
True indeed. But just want to know if it totally breaks stuff, but doesnīt seems that way.
I usually go frame by frame and compare the original to the Filtered, to see if i can see anything that shouldnīt be there, and it seems like itīs the way to go most of the time.
EDIT: Could you guys please try to Clean up the latest clip i sent, i want to know if you can do a better jobb than i have done. Which you probably can. Will post mine.
Code:AVISource("F:\Desktop\tff bff.avi") AssumeTFF() clip = SeparateFields() even = clip.SelectEven().assumeframebased odd = clip.SelectOdd().assumeframebased even1 = even.SeparateFields.SelectEven() odd1 = even.SeparateFields.SelectOdd() clip_even1 = MergeChroma(even1, odd1, 0.5) clip_odd1 = MergeChroma(odd1, even1, 0.5) out1 = Interleave(clip_odd1,clip_even1).weave even2 = odd.SeparateFields.SelectEven() odd2 = odd.SeparateFields.SelectOdd() clip_even2 = MergeChroma(even2, odd2, 0.5) clip_odd2 = MergeChroma(odd2, even2, 0.5) out2 = Interleave(clip_odd2, clip_even2).weave interleave(out1,out2) assumefieldbased() weave() ChromaShift( -2) ConvertToYV12(matrix="Rec601", interlaced=true) QTGMC("placebo") SelectEven() lsfmod(20) santiag(0,5) fastlinedarken() #DeHalo_alpha(rx=2, ry=1, darkstr=1, brightstr=1.5, lowsens=150, highsens=150, ss=1.5) # Motion compensation on frames -2...+2 super = MSuper () vf2 = super.MAnalyse (isb=false, delta=2, overlap=4) vf1 = super.MAnalyse (isb=false, delta=1, overlap=4) vb1 = super.MAnalyse (isb=true, delta=1, overlap=4) vb2 = super.MAnalyse (isb=true, delta=2, overlap=4) cf2 = MCompensate (super, vf2, thSAD=400) cf1 = MCompensate (super, vf1, thSAD=400) cb1 = MCompensate (super, vb1, thSAD=400) cb2 = MCompensate (super, vb2, thSAD=400) # dfttest on motion-compensated clip Interleave (cf2, cf1, last, cb1, cb2) dfttest (sigma=50, sigma2=50, tbsize=7, lsb=true) SelectEvery (5, 2) # Gradient smoothing presmooth = last SmoothGrad (radius=20, thr=0.15) SmoothGrad (radius=10, thr=0.25, ref=presmooth) # Back to 8 bits, ordered dithering Smoothtweak(saturation=1.15) #~ HQDering() #~ mergechroma(awarpsharp2(depth=10, type=1, blur=1, chroma=4)) #~ dehalo_alpha(ry=2,rx=2,darkstr=0.6,brightstr=1.0) Ditherpost()
But here is the entire code i have used.Last edited by zerowalker; 26th Feb 2012 at 20:51.

I use dfttest very much, i wonder is there any denoise that is better, or is better in some cases (maybe on realistic surfaces and stuff).
As dfttest can cause this, anti-realistic smooth look, but itīs extremely powerful, i really love how it works, itīs just that smooth look that isnīt that good all the time.
Though i am far from an advanced user, i just pretty much play around, and always use the motion compensation script. -
Okay i am trying to figure out a proper way of filtering and encoding a PAL VHS tape to DVD.
I need to keep it interlaced as itīs 25fps, and it becomes 50i, so i canīt deinterlace as MPEG-2 donīt allow 50p (if i am correct).
So there is the problem, as itīs very flickering and wavy, the QTGMC can deinterlace pretty neat and stable, while if i keep it interlaced it will fail on deinterlacing here and there, and also be a bit too unstable so to say.
Here is the script one got me at Doom9 with some small modifications from me.
Code:SetMTMode(2, 5) AVISource("Z:\Sandra 1 År\Sandra 1 År.avi") AssumeTFF() Mergechroma(SeparateFields().Blur(0,1).Weave()) source=ConvertToYV12(interlaced=true) bob=source.nnedi3(field=-2,threads=4) super = bob.MSuper(pel=2, sharp=1) backward_vec2 = MAnalyse(super, isb = true, delta = 4, blksize=16, overlap=8, chroma=false) backward_vec1 = MAnalyse(super, isb = true, delta = 2, blksize=16, overlap=8, chroma=false) forward_vec1 = MAnalyse(super, isb = false, delta = 2, blksize=16, overlap=8, chroma=false) forward_vec2 = MAnalyse(super, isb = false, delta = 4, blksize=16, overlap=8, chroma=false) bc2 = bob.MCompensate(super, backward_vec2) bc1 = bob.MCompensate(super, backward_vec1) fc1 = bob.MCompensate(super, forward_vec1) fc2 = bob.MCompensate(super, forward_vec2) Interleave(bc2,bc1,bob,fc1,fc2) dfttest(sigma=35.0,tbsize=5,sbsize=16,sosize=12,threads=4,lsb=true) Ditherpost() Edibob=SelectEvery(5,2).nnedi3_rpow2(2,nsize=4,cshift="Spline36Resize",fwidth=720,fheight=576,threads=4) Edibob.SeparateFields().SelectEvery(4,0,3).Weave().AssumeTFF() #QTGMC( Preset="fast", FPSDivisor=2, Ediext=Edibob,EdiThreads=1 ) Trim(0, 90632)
But as said it doesnīt work to well interlaced.(it looks stable with placebo QTGMC for example)
I am trying to figure out why, but itīs not going to well so i thought i would ask here again as i have gotten some serious help all the way before.
If you need more information or a clip before or after filtering just say the word.
Much appreciatedLast edited by zerowalker; 6th Jun 2012 at 03:46.

Without a sample of the original unprocessed capture, it's impossible to comment.
