You can't get VirtualDub to work with AVISynth scripts? It works fine for me. I've had no problem on 5 computers across 8 different o/s installations (Windows ME, Windows 2000, Windows XP SP1 & SP2). I've been using VirtualDub to test my scripts before feeding them to anything else since before version 1.4. The only time I used VirtualDubMod was when I wanted to edit an AC3 audio stream without decoding and re-encoding it.

VDubMod had it, Avery never felt like keeping it and fleshing it out. Ask him or fcchandler (vdub-mpeg2) what their plans in the area are.

Hi,
I hvave difficulty to run mvbob() inside the mvbob.rar package,
it always return error: "Scipt error: there is no function named: corrector"
anyone kind enough to give me a hand?
I also found a script mvbob1 seen work as good as mvbob as follows:

function MVbob1(clip c,int "blksize", int "pel", int "lambda")
{
order=(c.getparity==true)? 1:0

blksize=default(blksize,8)
scd=(blksize==8)? 300 : round(300/4)
pel=default(pel,1)
lambda=(blksize==8)? default(lambda,2000) : default(lambda,1000)

bobd=c.Leakkernelbob(order=order).verticalreduceby2()
fields=c.separatefields()
mvf=bobd.mvanalyse(blksize=blksize,pel=pel,isb=false)
mvb=bobd.mvanalyse(blksize=blksize,pel=pel,isb=true)

even1=c.separatefields().selecteven()
odd1a=fields.mvcompensate(mvf,mode=1,thscd1=scd).selecteven()
odd1b=fields.mvcompensate(mvb,mode=1,thscd1=scd).selecteven()
odd1=mergeluma(odd1a,odd1b,0.5).mergechroma(odd1b,0.5)

even2=c.separatefields().selectodd()
odd2a=fields.mvcompensate(mvf,mode=1,thscd1=scd).selectodd()
odd2b=fields.mvcompensate(mvb,mode=1,thscd1=scd).selectodd()
odd2=mergeluma(odd2a,odd2b,0.5).mergechroma(odd1b,0.5)

even=interleave(even1,odd1).weave()
odd=interleave(even2,odd2).weave()

interleave(even,odd)
}

what's the different?
also, someone send me a script, use whenever the edge not proper deinterlace, usage: mvbob().AAAFaster()

function AAAFaster(clip clp, bool "Scale2X")
{
Scale2X = default( Scale2X, false )
clp.Lanczos4Resize(clp.Width * 2, clp.Height * 2)
TurnLeft().SangNom().TurnRight().SangNom()
return Scale2X ? last : ReduceBy2()
}

Hi,

The filter "corrector" is not included in the last version of mvtools. Its now a standalone plugin, available at Fizick site.

See:

The most impressive thing about the Olympics was the outstanding standards conversion. The video was all 50i HD converted to 60i HD for American broadcast. I saw a few artifacts, but in general, the conversion was fabulous. I suspect on SD broadcasts, the artificacts would have been invisible.

Maybe someday this mocomp technique will approach that quality on PC-powered machines.

Hello everyone.
I am trying to do a standards conversion on NTSC(i) -> PAL(i), and i wanted to give a try to MVBOB.
I downloaded the Mvbob.rar file, and used this script.

#Import ("C:\Program Files\AviSynth 2.5\plugins\mvfpsscd.avs")
import("C:\Program Files\AviSynth 2.5\plugins\mvbob\mvbob.avs")
LoadPlugin("C:\DVD UTILS\dgmpgdec146\DGDecode.dll")
Mpeg2Source("G:\test\VIDEO_TS\test.d2v",idct=0)
mvbob()
lanczos4resize(width,576)
converttoyv12()
MVfps(50)
converttoyuy2()
assumebff().separatefields().selectevery(4,0,3).weave()

but i get "THERE IS NO FUNCTION NAMED MVFPS".
I tryied Avisynth 2.54 - 2.55 - 2.56, none of them worked.
I am sorry for the noobie question, but i am completly lost here.
Can someone suggest a script on testing the Standards Conversion with Motion Compensation?

Right now i am using other deinterlacers with good results, but not good results in panning camera.
That's why i want to test this aproach.
Any help will be welcome.

Kind Regards

try uncomment the first line that loads the mvfps function

[edit]

btw, if you want to try out a mocomp script, here's a simple one that gives good results on talking heads and such. deinterlacing isn't so important if your output is interlaced too - the artefacts aren't bad if your threshold is too low.

try leakkernelbob + clouded's "motionprotectedfps", then resize to pal and re-interlace. it's very fast, especially if you're used to mvbob + mvfps...

Thought so? I thought the complete opposite. It looked like a blocky mess to me.

Realy appreciate you help.
I did uncomment the first line of the above script, but it didn't make any difference.
I am trying now this script:

Import ("C:\Program Files\AviSynth 2.5\plugins\mvfpsscd.avs")
import("C:\Program Files\AviSynth2.5\plugins\mvbob\mvbob.avs")
LoadPlugin("C:\DVD UTILS\dgmpgdec146\DGDecode.dll")
Mpeg2Source("G:\test\VIDEO_TS\test.d2v",idct=0)

leakkernelbob(order=1,threshold=2)
motionprotectedfps(50)
lanczosresize(720,576)
assumetff()
separatefields().selectevery(4,0,3).weave()

I am encoding right now.
It is a clip from XXX movie NTSC Interlaced that has a lot of outdoors movement.
I hope i will see better results than with simple kernelbob + convertfps.
Do you think that MvBob gives better results?
I wish i could make it work, so i could try it to the same clip.

at least use securedeint() instead of leakkernelbob() since securedeint() avoids severe interlacing artifacts especially with handycam footage. Also it gives you better definition due to EEDI2 interpolation.

mvbob() would be even better, but it needs a lot of time to process.

scharfi,

could you update MVBob to use MaskTools v2 alpha?

Would it also be possible to add the option to input YUY2 data in MVBob and then output YV12? I understand that it must convert the colorspace to YV12 at some point so it would be nice if the colorspace was left to YV12 in the end to avoid having to do another YUY2->YV12 conversion.

I have plans to update it.

But not in the near future due to lacking time.

I've try the clip i mentioned before, and the panning is almost excelent using motionprotectFps, but i have some observations.

Using Leakkernelbob (order=X, threshold=1), gives me very good speed.
Using, Tdeint, i get much lower speed, but i get many many artifacts and lines (allthough i try to alter the threshold).
Using Securedeint(), i get wrong field, but sloooow speed (how can i change the order?).

These are the observations for the deinterlacers, but my main problem is that i have some tearing effects in the background.
For example, i have a small clip with some metalic curtains in the backround (i am sorry but i don't know how to call these).
You know, the metalic horizontal curtains everybody has in offices.
So, there are 3 White Ropes going vertical the curtains.
When the camera moves, these ropes get very very distorted.
What function can i call in MotionprottectFPS, to alter this?

Kind regards
George

you may try the raising the iterate parameter of motionprotectedfps().

also place an assumetff() or assumebff() before securedeint to ensure correct handling.

I can update it, since MT2 conversion is simple and adding an option for boulder is quick, but I'm in no way implying this is the way it'll work in scharfi's future releases. I added a yv12out boolean parameter.

Code:
		getparity(i) ? i.separatefields().eedi2(field = 3) : i.separatefields().eedi2(field = 2)
I believe this should be simplified to
Code:
i.separatefields().eedi2(field=-2)
In addition most of the isyv12 protections are useless, as ianb says a spurious ConvertToYV12 takes 0 time and no memory copies. (Just a pointer copy.)

Anyway, I, uh, have no interlaced material to test, so I just chopped up some cg video with one of your bob-to-interlace lines. It seemed to work the same, and was marginally faster... don't expect miracles though. (Looks very very good with cgi, btw.)

I submit the modified mvbob to your vetting. As usual, masktools2 is at its thread.

@kle500
Ugh, venetian blinds are going to be hard, if they're near the limit of pixel-differentiation. Many high-frequency patterns like that cause trouble for bobbers.

@scharfis_brain
Even if i raise the Iterate, there is no difference.
I tested the Mvfpsscd(50), and i see lower distortion in the above clip i mention.
But, way slower than with MotionProtectFPS(50).

Forgive me for my ignorance but, do you suggest to use Mvfpsscd in my clips?
As i mentioned before, i have NTSC interlaced videos that are all shot with camera (a lot of panning).
Any good suggestions?

@scharfis_brain:

Hi Scharfis! I'm having some trouble getting MVbob() and SecureDeint() to work with the latest MVtools (1.3.0). Could you please take a look at http://forum.doom9.org/showthread.ph...637#post838637 and let me know if I'm doing something obviously wrong? Thanks!
