I re-encoded Van Helsing from VOB again in order to test the new encoder.
The first time I ran Van Helsing, this was my info...
Code:
KVCD Format 704x480 - 1.40gb (NTSC) 
DVD2AVI v 1.76 Forced Film 
Target 2 CD's - 128k CBR Audio 

MPEG-1 
Max Bitrate 2376 - Min 300 
CQ-Value 70.49 
High Quality 
TMPEG Ver. 2.521.58.169 
23.976 FPS - Progressive 

AVISYNTH
Mpeg2Source("D:\Video\Rips\VH.d2v") 
BicubicResize(672, 336, 0, 0.6, 0, 9, 720, 461) 
FaeryDust(limit=2) 
UnFilter(50, 50) 
TemporalSmoother(1, 2) 
MergeChroma(blur(1.58)) 
MergeLuma(blur(0.2)) 
AddBorders(16, 72, 16, 72)
The second time I ran Van Helsing with the new encoder, I used this...
Code:
KVCD Format 704x480 - 1.50gb (NTSC) 
DVD2AVI v 1.76 Forced Film 
Target 2 CD's - 128k CBR Audio 

MPEG-1 
Max Bitrate 2376 - Min 300 
CQ-Value 59.78
High Quality 
TMPEG Ver. 2.524.63.181 
23.976 FPS - Progressive 

AVISYNTH
Mpeg2Source("D:\Video\Rips\VH.d2v")
UnDot()
FluxSmoothST() 
TemporalCleaner(5,10)
BicubicResize(672, 320, 0, 0.6, 0, 8, 720, 456)
AddBorders(16, 80, 16, 80)
Now I know that the borders and filters are different, but should it change the CQ value by that much?!?!? Plus the file size is bigger.

Also, ol Kwagster there encoded Red Planet (About 90 minutes) into 1 CD at about 70CQ.

The ratio just doesn't add up... Am I doing something wrong?

Hi Shibblet,

In order to make a proper comparison, your scripts must be identical.
They are not
And that can make such a big difference.

Well Poo!

Did you notice anything when you did Red Planet?

I'm working on a new version of CQMatic
I haven't really done any file size comparisions between versions.
My goal is to be able to take any source with CQMatic, with no matter what filters, and produce a very close to desired final file size.
I've been coding ALL day

Just stay tuned
