I am currently in the middle of the encoding the new Finding Nemo DVD to KVCD.
TMPGenc hasn't finished its thing yet, but CQMatic is telling me I can only get a CQ value of 50. This seems very low to me! (although in about 8 hours I will know whether it is acceptable or not to the eye )
I am using the optimal MA script.
Size: 480x480
NTSC 23.976
For some reason, I always have to include the line:
ConvertToRGB()
as the last line of all my Avisynth 2.5 scripts. Could this have anything to do with the low CQ?
Has anyone had any success with this movie at higher CQ values?
Many thanks!
Icarus

This is a VERY low value even for that movie. Can you give your script ? And the length of the movie ?

Dialhot:
Results turned out terrible! I think I will try with 2 CDs at 544x480.
This is the script I used:
Quote:
## Defined Variables and Constants ##
#
MaxTreshold = 1.50
nf = 0 # Current frame.
#
####
## Main section and static filters ###
#
Mpeg2Source("D:\My Documents\My Videos\Finding Nemo\Finding.d2v")
#
undot()
Limiter()
asharp(1, 4)
GripCrop(480,480,overscan=1)
GripSize(resizer="BicubicResize")
STMedianFilter(3, 3, 1, 1 )
MergeChroma(blur(MaxTreshold))
MergeLuma(blur(0.1))
#
#
## 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:
SwitchThreshold = (Width<=352) ? 4 : (Width<=480) ? 3 : 2
ScriptClip("nf = YDifferenceToNext()"+chr(13)+ "nf >= SwitchThreshold ? \
unfilter( -(fmin(round(nf)*2, 100)), -(fmin(round(nf)*2, 100)) ) : \
TemporalSoften( fmin( round(2/nf), 6), round(1/nf) , round(3/nf) , 1, 1) ")
#
#
#
GripBorders()
#LetterBox( Your_Values_Here ) # Depends on situation. Use MovieStacker!
Limiter()
#
#
## Functions ###
function fmin( int f1, int f2) {
return ( f1<f2 ) ? f1 : f2
}
#
####
converttorgb()

I also used a GOP value of 15. Is that right?
The movie is 101 minutes long.
Thanks,
Icarus

You don't need to use a tighter GOP with Computer Animated movies. Use the standard KVCD GOP of 24 max frames. That'll give you a much better compression and a higher CQ too!

I hate to be a quitter, but I eventually gave up trying to fit it all on one CD.
Two CDs @ 544x480 with a CQ of 88, and audio of 256 looks and sounds amazing - very hard to distinguish from original DVD!
There is so much detailed animation in this movie that fitting it all on one CD with the same quality is beyond my level of expertise.
Has anyone actually managed to get this movie on one CD? If so, please share your experience!
Thanks,
Icarus

I had no probs putting this on 1cd and it looks great aswell. Plus i'll defo watch the film again 'cause i thought it was really good. :P
Heres the details for ya:
File : 812 MB (812 MB), duration 1:40:23, type DSH, 1 audio stream(s), quality 40 %
Video : 697 MB, 971 Kbps, 23.976 fps, res. 352*480 (0.73:1), = MPEG Video, Supported
Audio : 114 MB, 160 Kbps, 44100 Hz, 2 chan., 0x50 = Mpeg-1 audio Layer 1, Supported
Can't remember exactly but i think i had bitrate set to MAX-2300 MIN-300 kbps using a MAF script.
Note, this was not encoded direct from a dvd but from a 1cd avi.
Hope it helps

Deva:
Can you post your exact script?
Also, what CQ did you end up with?
Thanks,
Icarus

Sorry Icarus but i did it a few weeks ago now and cant remember what the cq was. I can tell u i try not to encode anything with less than cq 65.
I dont have the log either, as far as i can remember i used the latest MAF script but just changed it from Temporalsoften to Temporalcleaner.
If i get time i will do another test for u

Very cute! but seriously, this is a popular movie, there must be someone else out there who tried to back this up on 1 CD?
My 2-CD version looks fantastic, but I'm still curious if anyone was able to get it on one CD with a resolution of 544x480, or would I have to go to 352x480 to make it fit?

I used SKVCD 352x480 and optimal MA template on one cd with 128 mp2. Results were very good. I don't remember CQ, but it was adequate.

That is generally true but... Most of this movie takes place underwater... Even if it's computer generated water that's not the easiest thing to compress.

I'm the last one to say that underwater scenes are easy to compress
However that will not change the fact that a tighter GOP with this movie will not be of any help!

hi,
I've gotten it on one 90min CD, file was 930 MB audio 128 kbps, video
mpeg2 480x576, 25 fps (pal), cq 63, max bitrate 2100.
The quality is the same as the source, but the source video wasn't really great quality. But the result is satisfactory....
It isnt a very high cq value, but the movie is difficult to encode due to the water-scenes...
