ghost effect on anime video

[loa-ash]

Hi guys!

I've this question for you to help in my rip, please...

I've upped 3 differents samples of my video to rip

http://loalainhtp.altervista.org/preview.avi [762KB]
http://loalainhtp.altervista.org/preview2.avi [1.54MB]
http://loalainhtp.altervista.org/preview3.avi [1.08MB]

this video would be cropped as best...then I must use ymc (yatta metric collector)with SClavc function selected to find the scene change for freezeframe, the last video artifacts are ghost frames I suppose....
I've read that the ghost frame is a problem about bad deinterlacing/IVTC or an eccessive temporal filtering...so the solution would be to do another IVTC???

ghost frames, freezeframe, bad crop... in your opinion there are other video artifacts?

Do you have any suggest please??

Thanks to all in advance. :)

Without seeing the original source material it's hard to guess why this progressive XviD encoding is showing blends. It could be that the original was field-blended. Or maybe the creator just used a blend deinterlacer. scharfis_brain is usually very good at guessing the causes based on the clues. Perhaps he will weigh in.

You may have some success with deblend filters. Do a search with "deblend".

Ok thanks for the reply!! :D :D
I've found the scharfis_brain posts in which he helps for removing blend fields; and I've also downloaded removebled 0.2.2 and Deblend plugins. This night I'll have so many free hours to test it on my videos and I'll await also the reply from scharfis_brain..

Thanks a lot
bye

I'm trying to using these filters:

LoadPlugin("C:\Programmi\AviSynth 2.5\plugins\decomb521.dll")
Loadplugin("C:\Programmi\AviSynth 2.5\plugins\unblend.dll")
avisource("file.avi")
unblend(threshold=5, dthresh=0.03, show=false)

but the problem remain... I've also try to do this:

avisource("file.avi")
DGBob()
unblend(threshold=5, dthresh=0.03, show=false)
Decimate()

nothing...

I really think that is useless to deblend because I haven't the original unprocessing source of this video :(

you could always try to decimate the ghost frames.

yatta is a very long process if your into doing frame by frame rebuilding. try using toms filter and see how well that works out for you.

Hi Xndo,

with yatta I must telecide and Decimate, so this is my project.avs

---------------------------------------------------------------

LoadPlugin("C:\Programmi\AviSynth 2.5\plugins\decomb521.dll")

function Preset0(clip c) {
#Name: Default
c
return last
}
AviSource("preview3.avi")

Telecide(hints=false,order=0,post=2,blend=true,ovr="preview3.avi.tel.txt")

PresetClip0=Preset0()
PresetClip0.Trim(0,82)

Decimate(cycle=5,quality=3,ovr="preview3.avi.dec.txt")

Crop(0,0,-10,0)
LanczosResize(640,480)

------------------------------------------

but I have the same problem....

No, he can't, becauseI really think that is useless to deblend because I haven't the original unprocessing source of this video(Unless he makes a VFR file afterwards of course, but I doubt he wants that, cause if he decimates frames away, his video will get out of sync).

I guess you only have a avi as source, right? Well, do as you did before, no Decimate, no telecide, but only sclav. Use project type 0 in yatta. Now you can have a happy time manually scrolling to the video and freezeframe all the frames you need to to. However, the ghosting is in motion, so if you freezeframe everything, your motion might get jerky. You need to play around. And some stamina to freezeframe thousands of frames.

Yes, I've only avi source, I've tried with YMC to detect scene change in preview3.avi.. in yatta I can't choose project 0 becuase it has not selectable but it is just in 0 option..
With freezeframe I must change one frame ghost (for example B) with A or C???

A B C
ok no ok

what's the best? after or before ?

Is impossible to do this work!!! :eek:

[lamer_de]

what's the best? after or before ?
I usually choose the one after the bad frame, but I guess that's personal preference.
Is impossible to do this work!!!Yes. But some sources are just bad. So you can either get another source, leave it as it is or try to make a botched repair.

Ok, thanks for all!!! I don't want wast my time with this source... I'll try another way... :(
