Any white-on-black text cut offs - when characters are looking directly at you :P

I think you are mis-understanding what ghosting is.

Ghosting is when you have like afterimages that don't completely disappear. So basically, you have semi-visible remnants of the previous frame/s blended into the current frame.

For a real life example, look at something extremely bright (e.g the sun), and then look away, you will have this semi-transparent image of (part of) the previous view burned into your vision for a while.

Don't think ef has any ghosting.

I think I know exactly what you're talking about. The thing which I did in fact point out to you.

That's a different phenomenon with a completely different origin to that of ghosting. It's called haloing.

But then you shouldn't have even close to 6 halos... (I still want that screenshot Sensei)

Talking about all that stuff made me slightly interested in trying to encode that said DVD (I've got it at home anyway). I'll see how I go.

Haloing hmm? [I only thought of it as ghosting cause that's what you said, but believe what you believe]

Well I used the incorrect treatment - but it still fixes it so I don't really care.

have fun encoding it I suppose~

Err....

No, I never said anything about ghosting. What I said, I remember, was something along the lines of "This DVD doesn't look authentic. Here's screenshot. Take a look at (around) the lines. Looks like someone extracted and remade it (and screwed up). That or the studio doesn't know what they're doing"

Look through the IRC logs if you don't believe me. I searched ghosting, there were 2 mentions, both by you. I never said that word. I always knew it was haloing, although I never specifically said the word "haloing' either.

Senseito Sakura Wrote:Well I used the incorrect treatment - but it still fixes it so I don't really care.

What did you do?

Well, if you attempted to fix ghosting, you would've probably also fixed haloing. Ghosting is much more serious, and extremely hard (like impossible) to fix, way harder than haloing.

Try this script

Code:

function DeHalo_alpha(clip clp, float "rx", float "ry", float "darkstr", float "brightstr", float "lowsens", float "highsens", float "ss")
{
rx        = default( rx,        2.0 )

brightstr = default( brightstr, 1.0 )
lowsens   = default( lowsens,    50 )
highsens  = default( highsens,   50 )
ss        = default( ss,        1.5 )

LOS = string(lowsens)

DRK = string(darkstr)
BRT = string(brightstr)
ox  = clp.width()
oy  = clp.height()
uv  = 1

halos  = clp.bicubicresize(m4(ox/rx),m4(oy/ry)).bicubicresize(ox,oy,1,0)
are    = mt_lutxy(clp.mt_expand(U=uv,V=uv),clp.mt_inpand(U=uv,V=uv),"x y -","x y -","x y -",U=uv,V=uv)

so     = mt_lutxy( ugly, are, "y x - y 0.001 + / 255 * "+LOS+" - y 256 + 512 / "+HIS+" + *" )
lets   = mt_merge(halos,clp,so,U=uv,V=uv)
remove = (ss==1.0) ? clp.repair(lets,1,0) 
          \        : clp.lanczosresize(m4(ox*ss),m4(oy*ss))
          \             .mt_logic(lets.mt_expand(U=uv,V=uv).bicubicresize(m4(ox*ss),m4(oy*ss)),"min",U=uv2,V=uv2)
          \             .mt_logic(lets.mt_inpand(U=uv,V=uv).bicubicresize(m4(ox*ss),m4(oy*ss)),"max",U=uv2,V=uv2)
          \             .lanczosresize(ox,oy)
them   = mt_lutxy(clp,remove,"x y < x x y - "+DRK+" * - x x y - "+BRT+" * - ?",U=2,V=2)

return( them )
}

function m4(float x) {return(x<16?16:int(round(x/4.0)*4))}

Don't worry if you can't understand it at all, just use. I don't understand all that either. Although I do get the main gist of it.

The HQ version of the ef visual novel OP. Because the streaming version I uploaded sucks. This is the least compressible thing I've ever encoded, and it just doesn't work at that size.

hehe, must be going nuts then

anyway - that 'dehaloing function' didn't really do much at all..

Maybe on other frames [though I doubt it], but I'm just working with one frame for now..

Frame 25 from DVD 6.

[The hilarious thing is that I haven't even tried my script on DVD 1 yet.. I got sidetracked by this PV and just continued trying to get somewhere, which I did eventually.. to an extent]

Spoiler for Version Frame 25 Comparison:

EDIT: Thanks for the up by the way :)
Really like that video

Increase strength.

I don't have DVD6 on me (only 1 and 2). So I can't do any testing myself.

... Halo. That's what a halo looks like.

That's some particularly strong haloing though.

Oh, by the way, HE-AAC is an extremely powerful codec (80kbps HE-AAC > 128kbps MP3). You would never really need 320kbps.

But then it's a very short vid. So I guess it wouldn't hurt the size much.

No I didn't.. I used Ghost-killing filters Hihi

Don't you think, like myself, it's extremely odd for the same thing to occur over MULTIPLE DVDs? Geneon or whoevers responsible should take note of this, this isn't right for the price Anime DVDs go out in Japan for anyway.

It just couldn't be the person who done the ISOs... I mean, it takes effort to inflict what appears to be 2 Main Levels of Haloing.. and like said, it isn't just a minor level. Rawr... I'll see if I can deal with the next (darker) level today..

I'll keep that in mind..... and HE-AACv2 for extremely low bitrates, right?

That's good. Because if you did denoise it enough to kill the halos, you just killed every detail that's there in the rest of the picture as well. Then I would need to stab you.

Ghost killing filters? Ghosting is generally extremely hard to remove, and even if you do, it won't be a perfect removal, since there is no way to recover what was lost (what was covered by the ghost). Mostly, it's very hard (for the computer) to detect what's a ghost, and what's not.

Which ghost removing filter? Ghostbuster? (« that I think attempts to do subtraction).

Could be that it's originally like that, when they produced it. (= studio doesn't know how to sharpen).

But if that's really the case, then wouldn't you think they'd try to remaster the DVDs to remove the halos?

Yes

Ghostbuster I tried already, it failed - doesn't work AviSynth 2.5 v_v

Also tried Exorcist through VDub Filter Loader - but it literally destroyed the image.

I'm using WarpSharp Package EraseGhost now.

Yeah

I'm trying to get this last layer and it's such a bastard lololol

S7* · 27/09/2008 05:10 AM

I've managed to improve my script.

The Second use of the filter was too weak - my bad.

After strength increment, the 'dark line' was gone and the difference was a lot more specific..

I'm going to see if modifiying again or adding a third line will solve it completely... hopefully.

it's all about trial and error isn't it ^^'

That's just on this frame (the only frame I have). Don't know it'll look on the rest of the video.

For filtering, yeah, kind of.

Of course, you need to know where you're heading to start off with, otherwise you'd just get lost.
