KVCD: Can only encode with CQ of 40?
 

hey guys hope you can help!

i'm trying to encode a 100 minute pal dvd rip onto one 80min cd
but when i use tok it encodes at CQ of 39.1!!! :roll:

why am i getting such a low CQ :?

Maximum bitrate is set to 2500 and minimum is set to 300, the audio is 128kb .mp2

here is my script, i am new to using avisynth and filters, i usually just load the templates into tmpgenc :oops:

## DLL Section ##

LoadPlugin("C:\Documents and Settings\Ben King\Desktop\kvcd encoding tools\filters25\MPEG2Dec3.dll")

## Defined Variables and Constants ##

## Linear Motion Adaptive Filtering ##
#
# ( Portions from AviSynth's manual ) - This will apply temporalsoften to
# very static scenes, and apply variable blur on moving scenes.
# We also assign a variable - and this is why a line break is inserted:

ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf > 2.5 ? asharp( -(fmin((nf/30), 1)), 0 ) : \
TemporalSoften(2,7,7,3,2) ")

#
#
#

GripBorders()
#LetterBox( Your_Values_Here ) # Depends on situation. Use MovieStacker!
Limiter()

#
## Functions ###

function fmin(float f1, float f2) {
return (f1<f2) ? f1 : f2
}

With the motion adaptive script, it's not a bad thing to get such a low CQ value. It's not an absolute value for quality, CQ50 with a higher resolution may look better than CQ70 with a lower resolution. Examine the sample clip and you'll see if you like it or not.

However, you can try lowering the resolution to 480x576 or 352x576 and see how that comes out.

i watched the sample clip and the encode was very blurry and blocky, much worse quality than most vcd's. I've heard of people getting very good encodes with 100 minute movies on one cd and am wandering what they do! :roll:

any pointers guys??

thanks

Looks to me that you'll just have to lower the resolution or use two discs. You could also post the ToK log file so we'll see if there's anything wrong with it.

Can you give us the length of the sample and the length of the audio file ? And if possible, copy the log of Tok.

hey guys, sorry for the late response!

the audio size is 91.4mg encoded with headache
the sample video size is 1.04mg

this is the Tok log file:

thanks for your help! :lol:

Okay...

It seems that you find the perfect example where Tok + PAL + New adaptative script leads to a complete disaster :-(
