Deinterlacing Artifacts, Ghosting ?!

[darkwolf]

Hi,

Source Bluray NTSC
Scan Type: MBAFF
Frame rate: 29.970 fps

Can't seem to deinterlace this source without artifacts or ghosting.. anyone could help me out please.

I tried almost all the pluggins i knew for deinterlacing without success.

This is the best i could get:

Check the red line ...

Some kind of black line\shadow around the plane and both guys.



Best result i could manage was with this:

DirectShowSource("C:\x\1\test.m2ts", fps=29.970, audio=false, convertfps=true)
Load_Stdcall_Plugin("C:\Program Files (x86)\MeGUI\tools\yadif\yadif.dll")
Yadif(order=1)
crop( 4, 0, -4, 0)

LanczosResize(1280,720) # Lanczos (Sharp)

ConvertToYV12()

End result is for a mkv...

If needed i could upload a small sample of the m2ts (If i could find a place to send it)

Thanks

First of all, get rid of DirectShowSource. It looks like an incorrect YV12i<>YUY2i conversion has happened already upon loading of the source. Figure which codec is used for the video track inside the *.m2ts, then use a dedicated decoder.

This is what look like the source:

Any sugestion on what i could try to get a proper deinterlacing .. or how i can fix this source.

As sugested i used LoadPlugin("C:\Program Files (x86)\Haali\MatroskaSplitter\avss.dll")
dss2("C:\x\1\test.m2ts", fps=29.970)

But still have the same issue.

posting a video sample of the source might help

free hosting sites: mediafire.com, sendspace.com

There a sample file:

Well seem like i fixed it using dgavcindex.

LoadPlugin("C:\Program Files (x86)\MeGUI\tools\dgavcindex\DGAVCDecode.dll")
AVCSource("C:\x\1\ciboire.dga")
Load_Stdcall_Plugin("C:\Program Files (x86)\MeGUI\tools\yadif\yadif.dll")
Yadif(order=-1)
crop( 4, 0, -4, 0)

LanczosResize(1280,720) # Lanczos (Sharp)

Seem perfect now.

I would really like to know what I did wrong when i used directshow or dss2.

I would suggest you demux it to H.264 > then create a .dga file with dgindexavc (Megui > tools dir). Decode with AVCSource(). I tried "yadif(order=1, mode=0)" and it looks nice.

EDIT

I was typing while you replaced with a .dga :).

[poisondeathray]

what decoder were you using for directshow? that might have been the culprit

e.g. using directshowsource + ffdshow worked fine with your sample

beware of blocky decoding artifacts when using dgavcindex with some PAFF streams - this is a known issue

[darkwolf]

graphedit show me "Microsoft DTV-DVD video decoder" as video renderer for the m2ts.

might be why my directshow wasn't working right.

But still doesn't explain the weird behavior with dss2 using haali media splitter...

I'll install ffdshow.

[poisondeathray]

on win7 you need clsid's codec tweaker to override MS filters

Yah i knew how to get them working and override M$ one.

Installed ffdshow & did another test with directshow all working fine now.

Moral of the story don't use M$ codec !!

thanks guys...

Try also ffvideosource and ffaudiosource.
