i'm encoding an old anime caled escaflowne i have a problem that just eats the bit rate

the problem is the outlines of the anime it moves up and down alot its like every frame is difrent i can encode it but i still dont get the quality i want when i open the stats file of xvid it tells me the the size is 350 for a 20 min ep and i dont know how to fix it or what to use

clip: http://www.geocities.com/nightmare30002003/problem.avi
this is not from the source but it shows the problem

edit: I changed the title. Please use an appropriate title next time.

Looks like plain old analogue anime where the cel sheets have been placed by hand, causing slight offsets frame-by-frame. Would be nice if someone invented an anime deshaker for this.

What did you do to encodet the Vid? Please descripe the complete way. I don't think mf is right. It looks more like a problem with interlacing.

i used this with xvid

Telecide(order=1,guide=1)
Decimate(mode=2)
FieldDeinterlace()
LanczosResize(640,480)
Undot()
Convolution3d(preset="animeLQ")
aWarpSharp(15)

It looks like a problem with deinterlacing because the sheets moved so slightly that it's causing bad IVTC matching (same reasoning as why anime mouths don't match IVTC).

i dont know how but i instaled the old avs 2.5 insted ot the 10/11 version and it fixed the problem

i think decom 5.1 just didnt work well with the new version

Agreed, this looks more lika a problem with Deinterlace or IVTC, but the topic is interesting, nevertheless. 'Cause there are plenty of old anime that could really need such a treatment, where the cels have not been placed correctly and the picture eats more bitrate than it would need to.
Any idea how to correct this with Avisynth?

@Nightmare: You sure that is Escaflowne? Looks much like Ruin Explorers to me :confused:

that line flicker is on the source itself. anime dvd is commonly authored as such with poor telecine, especially from master svhs tapes. shows the most on horizontal panning. or it may be imperfect transfer, who knows.

you can try any version of ivtc or play it back on your pc and it will look that way with the shimmer. personally tried both legacy and 2.5 versions of decomb and either you end up with blurred ivtc or sharpened ivtc and shimmer remains.

Sorry, you could probably misread my sentence about "Problems with Deinterlace or IVTC" . I fully acknowledge that current filters give clean output if the sources are clean, too.
I was just wondering, if there is a way to correct bad masterfiles with moving lines, due to cel misplacement or whatever, afterwards in Avisynth ?

maybe bluring the lines would help cuz sharpning will make it worse

interlacing is a huge problem here too its heavy and if i get rid of it the shimiring becomes worse

the only ways to deal with it is to either blur luma or try and aggresively dup frames. or use temporalsmoother (a dangerously strong temporal filter)

you can get rid of most of that shimmer, just takes a more complex script.

maybe u can sugest a script with the filters needed

cuz i started to encode escaflowne and im up to ep8
it takes a long time to encode using xvid about 2 hours 30 min
