How to remove ghosting for anime?

[rhaz]

Hi. I use MeGUI to encode from DVDs to x264/.mkv. I used this script:

LoadPlugin("Decomb.dll")
Telecide(order=1,guide=1).Decimate()

And got this:


The interlacing is gone and etc, but I noticed those strange artifacts. Can someone explain me how that is called and what is the solution, if any.

Also I noticed FPS from 29 dropped to 23.

Of course it did, you have performed inverse telecine processing.

To be exact from 29.97 fps to 23.976 fps. Most likely that ghosting effect was already in source before telecine conversion.

So in other words...?

If you apply SeparateFields() on the unprocessed original source, do you still see the artifacts?

In that case, the source probably has been subject to field-blending at some point during production and there is no way to simply "undo" this.

Though, something like Srestore might be able to reduce the blending...

[rhaz]

Yeah, I tried that and srestore but I get same result.

Next question then, why it has so many dupe frames? Or is it supposed to be like that for animations?

[LoRd_MuldeR]

Yeah, duplicate frames are not unusual at all in animations...

Now you need to post a link to an unprocessed source sample that we can use to duplicate the effect. You can cut VOBs with DGSplit.

Looks like it's a chroma offset thing. Here's a crude way to fix it.

#avisynth 

## requires AVSLib
## http://avslib.sourceforge.net/
LoadModule("avslib", "filters", "channels") 

C=ImageSource("UWUGuoa.jpg")
C=C.Crop(0,0,C.Width-(C.Width % 2),C.Height-(C.Height % 2))
C=C.ConvertToYV16()

Y=C.ShowY()
U=C.ShowU()
V=C.ShowV()

return StackHorizontal(C, MergeYUV(
	\     Y, 
	\     Overlay(U, U, x=0, y=2), 
	\     Overlay(V, V, x=1, y=3)))
