I dont know why this is happening, it seems kinda odd, since most problems have to do with getting the file smaller ^_^;; But anywho..

I am encoding Read or Die (anime) and, since its 3 eps, i am using 233 for each of them (1 CD). And for some reason, after about 6 tries, i can not get the first episode to about 210mb (need room for audio) its maxing out around 130, which is terrible quality. Here is my .avs:

----------------------------------------------------------
LoadPlugin("D:\mpeg2dec.dll")
LoadPlugin("D:\decomb.dll")
LoadPlugin("D:\warpsharp.dll")

mpeg2source("D:\_Read or Die\1\readordie_1_30fps.d2v")
Telecide()
Decimate(cycle=5)
crop(4,0,712,480)
BicubicResize(640,480,0,0.5)

Tweak(Sat=1.4,Bright=10)
WarpSharp(depth=128, blur=2, bump=150, cubic=-0.6)
----------------------------------------------------------

I'm doing a 2-pass, and i have tried different sizes in the 2nd-pass int thing too, nothing seems to work. Even tried making the avg bitrate way higher, nothin. Any help is great, thankyou ^_^

Please post your XviD settings also (including all the settings and destination size) otherwise we cannot help. If you search the forum for undersize or similar you'll find some posts with similar issues and how to improve them.

Infact there is a thread just underneath this entitled "XviD Filesizes" (or similar). Please search before posting and your comments to similar threads before creating a new thread.

Looks like I should add a "What to do if your encodes are undersized" to the FAQ.

^_^ ...and the first thing that springs to my mind would be 'drop the noise-filters'.

in Xvid to get bigger files
*you might want to turn off LumiMasking if you enabled it (LM ON can decimate anime to half the size)
*try with QuarterPel ON/OFF (on has always given me smaller anime videos, OFF is much faster)

for AVS you might want to try
Mpeg2Source("..d2v", cpu=6, iPP=true)
# i use TomsMoComp(0,3,1) right after, but dunno bout NTSC stuff #

i.e. NO warpsharp et all. the cpu=6 in Mepg2Source i can highly recommend, it does a good job in removing mpeg2 artifacs and you most likely wont need denoisers for DVD anime - have you ever looked closely at trees/weed etc in anime with strong denoise? it looks horribly flat. if cpu=6 is too strong or slow lower it. if it's too weak add the unfilter:)

there sure is more, i am fighting against undersize since i use koepi 2003-05-14 , it seems to drastically increase compression efficiency - i had to completely drop the complex filter chains i used before ;)

There are several things that you can do to make your anime harder to compress, but I find the best way is to use the custom QM "CG-Animation", which you can find in another thread. That will make your files much bigger than using the h263 QM.

Also, you might as well plan to fit all three episodes in that 700MB of space on a (compression ratio * firstpass size) basis rather than fixed 233MB/ep size, since each episode will compress differently.

If that doesn't make sense to you, then here's a rundown. 1. Encode the audio stream for all three episodes 2. Do a firstpass for each episode. 3. Calculate 700MB / (audio stream total + firstpass total). 4. Then compress each episode by that value.

The only time you want to be using fixed sizes is for fansub releases, since you can't tell in advance how three/four episodes will compress.
