Hi there,
Getting a movie less than 110 minutes on a single CD-R is what I have been trying to do for a very lone time. Due to thousands of failures, I use 2 CD-Rs instead of 1 since a long long time ago. But I really want to know what have I done wrong.

My source is always DVD, the original aspect ratio is 2.35:1 (which is the shortest in height available in DVD, I guess), sometimes the aspect ratio is 1.85:1. I used SKVCD but change the resolution to 480x480 instead of 352x480 but it is still smaller than 544x480. I convert audio to 128Kbps (MP2). I tried every script combinations including the latest script thread in the forum. I did set TV overscan to 2. I just don't know why I can't set CQ anything higher than 50 to keep video stream under 700MB (the quality of 50CQ is not acceptable to me). I set the min. bitrate to 600 and max. bitrate to 2200, still fail. What CQ value do you people have to fit a FULL movie onto 1 CD-R? What is your script? Thanks in advance.

Raising your min. bitrate (600) is going to be pretty though to fit all in one CD I would think. Thats why you are at 50%CQ.

Hi syk2c11,

Have you tried processing your .avs script with ToK
Do you get the same results

Hi Kwag and others,
Here is my script for your reference.

LoadPlugin("D:\Working Programs\Fit CD\MPEG2DEC.dll")
LoadPlugin("D:\Working Programs\Fit CD\legalclip.dll")
LoadPlugin("D:\Working Programs\Fit CD\sampler.dll")
LoadPlugin("D:\Working Programs\Fit CD\DustV5.dll")
LoadPlugin("D:\Working Programs\Fit CD\UnFilter.dll")
LoadPlugin("D:\Working Programs\Fit CD\STMedianFilter.dll")

Mpeg2Source("F:\Ripped VOB\007-2\007.d2v")
LegalClip()
Unfilter(50,50)
BilinearResize(448,416,69,0,582,480)
STMedianFilter(8, 32, 0, 0, 8, 32)
Temporalsmoother(1,2)
Mergechroma(blur(1.5))
Mergeluma(blur(0.2))
AddBorders(16,32,16,32)
LegalClip()

#Sampler(length=24)
## MPEG size = ((Total frames/MovieTimeInMinutes)/24) * MPEG sample file size ##

I purposely increase the height as you can see above, but it is not that much, I don't think it is the cause of the problem.

I think ovg64 hit the nail on the head. At 110 minutes, the average bitrate can only be something like 850, so a minimum of 600 is way high and will knock your CQ value down. Try using the standard template values of 300/2500 and see what happens.
