Help Deinterlacing anime clip

[_E_]

Heya.

I've been trying to deinterlace an anime episode encoded into 29.971 FPS. After a few tweaks, It became apparent to me that using

Telecide(order=1,chroma=true)
LanczosResize(720*2,480*2)
SangNom()
BicubicResize(720,480)

eliminates interlacing and the ghosting present in the clip. However, There are some scenes where the chroma seems to be shifted/out of place. I have tried different settings with Telecide , I even tried TomsMoComp and KernalBob/Blend but without any luck. Can anyone suggest a solution for my problem? Attached are a few pics of corrupted scenes along with a link to a 45 sec clip ( Please download it if you feel you can do something, I don't have much spare b/w atm ). Any help would be appreciated. Thanks~!

could you give a sample vob?

All I see in your highlighted areas is mosquito noise. But given the artifacts from your red circling, that may have come from the JPEG compression. So I second the request to provide a VOB fragment.

I'd wish ^^;; To make things short, a friend asked me to encode a DVD source re-encoded into DivX ( which is what I have atm). I've been trying different techiques till now and still no luck, so I am guessing this source is hopeless, huh? I could have gone back to the original dvd and be done with, but I found this problm to really wierd, hence why I am seeking a solution. *edit* I ll upload a sample vob anyway*edit2* : Original Source sample (http://elly.flaretech.net/VTS_13_1.VOB)

That's quite true, some artifacts come from the lossy jpeg compression, however if you look closely ( especially into the white coat in the first pic ), you ll notice the red/orange colour from the tail tainting the man's white coat, which is what's making me go crazy.

P.S. Your VOB link is dead.

i don't see it either. only the interlacing stuff and the mosquito noise. I wish I was always working with those great sources.

EDIT: neuron2 that's a good comment. we should have a "who has the crappiest Anime DVD source" contest.

Guess you would win the contest then... ;) :D :p

Next time better use PNG instead of heavy compressed JPEGs !!!

_E_ , to save your mind: I do see color ghosting there. In the first screenshot, it is even obvious. Although the red circles are more like hiding of the artefacts than spotting them, that's true ;)

But your source is beyond my current bandwith. So, question: are these color ghostings "one frame" artefacts, or do they last longer? If they're as short as one frame, one could probably trick something with clense().

[scharfis_brain]

the sample clip is encoded with divx (or something else MPEG4-like) without paying attention, than the clip is interlaced.

This is the reason for the chroma ghosting!
Interlaced video, that has been encoded with a progressive codec will look fine at first view, but the chroma is BLENDED between two fields!

There is no way to fix this.

So get the original DVD. There You won't see any of those artifcts.

Delete this AVI-File!

One Frame artifacts. A chroma ghosting gets repeated every 4-5 frames or so ( I've thought of decimating every 5 cycles, which got rid of some of the bad frames, but ofcourse, that's not the way to do it ;) ) What you say sounds interesting though, care to share your thoughts? ^^;


But yeah, I already deleted the avi ( The sample is still up for anyone to see though). I was hopeless when I posted in here, but at least I got the reason why is it causing that, thanks scharfis_brain :)

kk, next time I'll post in pngs...

[ChronoCross]

can you post the vob? the link seems to be broken.

What, no mind reading today? :)

"Hmh, one could try to do a temporal sharpening effect until the ghost colors fall outside of [ color{N-1}, color{N+1} ], and then clense it .. .. apply result only if clense() actually did something, else keep original."

All about laser eyes. If you can't shoot eye beams from your eyes, you can't see the artifacting.
I properly roasted the postman the other day while looking at those pictures. He wasn't ready for it. Today I saw him coming down the road with a radiation shield just in case I was encoding again when he delivered my post :P
