easy:
choice the template here(352x240lbr):
http://www.kvcd.net/dvd-models.html

and use this script(change what you need):

[AVISYNTH_LanczosResize, Fluxsmooth, Blockbuster, Legalclip]
0=LoadPlugin(!FluxSmooth.dll)
1=LoadPlugin(!Blockbuster.dll)
2=LoadPlugin(!Legalclip.dll)
3=LanczosResize(^TargetWidth,^TargetHeight)
i4=FluxSmooth()
5=Blockbuster(method="noise",detail_min=1,detail_m ax=10,variance=.5,seed=1)
6=Legalclip()
7=AddBorders(0,^BorderTop,0,^BorderBottom)
!FluxSmooth.dll=C:\xxxx\FluxSmooth.dll
!Blockbuster.dll=C:\xxxx\Blockbuster.dll
!Legalclip.dll=C:\xxx\Legalclip.dll


ps:
i use this script in dvd2svcd

gulp i knew it would be that equation, have had bad experiences with that equation which involve a waste of many hours

Question (lol yeah sorry i ask so many)
why do u divide by 24 in that equation to get the wanted mpeg sample size?
when using skvcd do i want to take a cd as 700mb or 800mb? i wouldve thought 700 cos its svcd

extract part of :

http://www.kvcd.net/forum/viewtopic.php?t=2102

read thisstep 2)

"...so a 700MB data CD-R will actually fit ~800MB in VCD format. So we'll use an 80 minute CD-R for this example."

in the same thread in next page:
http://www.kvcd.net/forum/viewtopic....e60eef7dd3398d

the BETA-1a notch :
8 9 12
9 10 14
12 14 18

GOP 1-12-1-1-24

change this values in the template, or in setting(tmpgenc).

ok i done that(u told me to change matrix and gop), heres my maths
from this post: http://www.kvcd.net/forum/viewtopic....92b3230f1a671a

i took cd size as 813,019,155

813,019,155 * 3cds = 2,439,057,465bytes or 2326.06646060943603515625 megabytes - audio size (167mb) total video size = 2159.06646060943603515625mb

movie is 208896frames long and 139.2667 mins long

using formula
208896/139.2667/24 = 62.498803255146002872187649593107

2159.0664606094360351562/62.498803255146002872187649593107
predicted sample size = 34.545724848446016218147225796569
managed to find cq_vbr value of around 22.0956
that sound ok?
