Just went through the Decomb Tutorial with decomb500b16.dll.

The results were:

Telecide(order=1,guide=1,post=2,vthresh=28,show=tr ue)
Decimate()

My script from MovieStacker is:

mpeg2Source("h:\wintvvid\film.d2v")
Trim(5476,42104)+Trim(48856,66436)+Trim(73961,9819 6)+Trim(105120,127739)+Trim(134815,150149)+Trim(15 7380,179084)+Trim(187199,202904)+Trim(210113,21965 9)
ConvertToYV12()
Telecide(guide=0, gthresh=30, post=true, threshold=15, dthreshold=9, blend=true, show=false, agg=false, reverse=false, firstlast=false, chroma=false, nt=0, mm=0)
Decimate(cycle=5, mode=0, threshold=0, threshold2=3, quality=2, show=false)
GripCrop(704, 480, source_anamorphic=false, dest_anamorphic=true)

decomb500b16.dll gives me avisynth errors. I have been using decomb_25_dl_20030327.dll with avisynth 2.52.

What should the decomb_25 dll line for Telecide() look like with the information generated using decomb500b16?

Also, how should I modify the decomb_25 Decimate() line?


Really confused.

Well there is a non beta Decomb plugin of 5.0 at http://neuron2.net/decomb/decomb.html but somehow the page is down.
But you can try SmartDecimate at http://forum.doom9.org/showthread.ph...threadid=60031
It is the rival of Decomb I think it is just at good....maybe better.

Hopefully that will help you, if you have anymore problems post what type of movie you are doing if its cartoon/anime or live action, a lot if its interlaced or not.

I just love the advice from Dial_Hot to use the internal smartdeinterlace function of the MPEG2Enc3.dll engine.
Just Add (in YUY2 Mode) ...

SmartDeinterlace(2,15,true,false,true)

To your script, its a very good and fast adaptive deinterlcing engine. But it doesn't performe a InverseTelecine.

I think that a crashbug was fixed before Decomb got off beta. Get the v5.0.0, it should work fine.

http://neuron2.net -> Mine -> Decomb Filter Package.

You don't need the ConverttoYV12 line, MPEGs are already in YV12 (make sure you use MPEG2DEC3.dll).

EDIT: your script should look like this:

Code:
mpeg2Source("h:\wintvvid\film.d2v") 
Trim(5476,42104)+Trim(48856,66436)+Trim(73961,98196)+Trim(105120,127739)+Trim(134815,150149)+Trim(157380,179084)+Trim(187199,202904)+Trim(210113,219659) 
Telecide(order=1,guide=1,post=2,vthresh=28,show=true) 
Decimate() 
GripCrop(704, 480, source_anamorphic=false, dest_anamorphic=true)

Thanks, Boulder!

"The package automatically adapts to any telecine/capture patterns, e.g., 3:2 NTSC or 1:1 PAL, and mixtures thereof, although if you want to decimate the recovered progressive stream, you have to specify the desired decimation ratio."

How do I find the decimation ratio?

The ratio is most likely one duplicate every 5 frames. Which means you can just forget it and use Decimate() which will turn your 29.97fps capture into 23.976fps, removing the dupes.

Great, and, thanks!

Seems to be working so far. I'm trying out my new PVR-250 capture board. I'm capturing mpeg's at 720x480. The best script seems to be the MA one, with high quality rather than motion estimate. The best template seems to be KVCDx3-2 reset to 704x480.
