quality has increased/decreased between kvcd templates?
 
I'm currently encoding 'The Sixth Sense' with the brand spankin new x3 template. At first I was a wee bit dissapointed with the time estimate in Tempgenc, but after 4 hours I'm looking at only 150 megs for 30 minutes of video!! 8O !! This will easily fit one CD! I did most of it overnight, so I wasn't able to eyeball quality, but the source is a Divx file, and not the best Divx file, at that. Kwag, care to chime in here on whether the quality has increased/decreased between this and the 'old' x3 template?

P.S. This encode marks my first foray into Avisynth. It's not as hard as I thought. Sansgrip, thanks for your help. Couldn't have done it w/out ya...
This clip will have Fluxsmooth and Blockbuster anti-crap countermeasures applied to it :)

P.S.S. Does the new x2 Plus template incorporate this technology as well? I'd like to compare the two, side by side....

Well, I got antsy, stopped the process, and looked at my output. I'm pretty sure I whizzed on the electric fence as far as Avisynth is concerned, because it looks terrible. Blocks, artifacts, mosquito noise, the works...

Here's the script in question -
What did I screw up this time?
------------------------------------------------------------------------------------

LoadPlugin("C:\Program Files\Fit CD and Avisynth Filters\MPEG2DEC.dll")
LoadPlugin("C:\Program Files\Fit CD and Avisynth Filters\blockbuster.dll")
LoadPlugin("C:\Program Files\Fit CD and Avisynth Filters\legalclip.dll")
LoadPlugin("C:\Program Files\Fit CD and Avisynth Filters\sampler.dll")

AviSource("C:\Documents and Settings\Steve\Desktop\Patch Adams.avi")
LegalClip()
BilinearResize(448,318,14,0,692,436)
Blockbuster(method="sharpen", detail_min=20, detail_max=90, strength=6)
AddBorders(16,129,16,129)
LegalClip()

BB_Resolution = 528*480

BB_StrengthConstant = 352 * 240 * 20 # Base strength
StrengthValue = round (BB_StrengthConstant / BB_Resolution)
Blockbuster( method="noise", detail_min=1, detail_max=10, lv=1 ) # Apply noise if complexity is <= 10%.
Blockbuster( method="sharpen", detail_min=20, detail_max=90, strength=StrengthValue) # Sharpen only if complexity is >= 20% AND <=90%.
------------------------------------------------------------------------------------

Thanks in advance,

Steve the bumbling moron.

Check out the Guide to convert Divx (avi) to KVCD.
Your avs script is way out of date.

Awesome, Black Prince!

I'll use your script from the guide (with His Majesty's permission), and try again!

Have you tried the new templates? Can you voice an opinion on the quality vs. size?

Also, I've found the Blockbuster sharpen filter to do bad things with most DivX sources. FluxSmooth() is your friend, however.

@Reno,

I followed the whole development project and did some testing to
help with the final new GOP and Q-Matrix. CQ gives the best
picture quality. It's downfall is predicting file size. The new
templates not only improve picture quality (e.g. artifacts, flashing,
Gibbs noise, DCT noise or blockiness, etc) it has also reduced file size.
My guide points to the link for the new templates, so you are using
the most current updates in filters and templates. When you finally
get throught the process with great picture quality and it fits on 1 or
2 CD's, you'll use KVCD for all your backups like I do :D
