I have noticed a brightness around the edge of letter boxing that seems to shimmer but I always thought it was just because my very old TV couldn't handle the brightness/contrast...because on darker scenes I don't notice it.

It might be the result of the borders not being a multiple of 16. If they aren't they'll occur in the middle of a macroblock, and artifacts will appear.

I found it most prevelant in animation ie: disney, almost to the point that it is unwatchable not so much in normal movies. I think I might do some more testing with the new matrix etc as this was early on in my kvcd experience.

I don't know if it's the same thing, but if I burn a 352x288 clip as SVCD, there's that shimmering. I suppose it's caused by the standalone player (Pioneer DV-343) which thinks that the clip is SVCD and therefore 576 lines and doesn't stretch the picture correctly. If I burn a 352x576 clip, it plays like a normal SVCD.

Burning as SVCD is the only way for me to get rid of audio clipping. It's really of no use to make a 352x288 clip with a minimum bitrate of 700 or so. I'll rather go for a larger resolution and use a minimum of 150 or 300 (150 does work fine for me).

Did you find it necessary to use Cnr2 with a DVD rip? I thougth it was more useful with captures from analog (tuner or VHS).

Kwag,

what's the latest prediction formula? You've been talking about a factor of 0.98 but I'm not sure where it should be in the manual calculation.

I was just testing denoisers

. I've since stopped using that one because it seems to produce visible chroma ghosting.

@All,

Just encoded "Blood Work", 1hr 40minutes, using KVCD-LBR (352x240),
GOP 1-24-2-1-24, Q-Matrix Notch (Beta-1a), CQ = 80. The result,video
file size 688MB, audio 160kb, final A/V file size 798MB. Picture
quality is Fantastic

, EXCEPT for Gibbs, Gibbs, Gibbs.

This is the best LBR by far that I've made

Flashing was gone, no
artifacts, DCT noise was gone, but Gibbs was good but still noticable.

What can be done about Gibbs noise.

Do you have a preference for any other Chroma stabilizing filter? (I like flaxen's VHS, but it's in for vdub).

Why use LBR for 1h40m?

Not a lot. It might be possible to tweak the matrix, but the compression has to come from somewhere...

Could someone provide a link to these filters? I have looked everywhere, searched these forums and doom9...

must be missing something somewhere

thanks in advance

http://www.doom9.org/index.html?/software.htm

after click in "(show me more)" in the page,ok?

dreamhost · #**615** 01-28-2003, 10:40 PM

thanks, I found the first one, but can't find the vobsub.dll
I downloaded everything that said vob, unzipped but still no vobsub.dll
help

Hi everybody!!

I just wanted to know wich is the latest high quality script and the latest prediction formula, anyone knows or have an aproximated idea?

Any help will be appreciated!

Saludos para todos,
DaDe.

kwag · #**618** 02-14-2003, 12:13 PM

Hola Dade

Here's a script I'm using:

Code:

LoadPlugin("C:\encoding\mpeg2dec.dll")
LoadPlugin("C:\encoding\GripFit_preview.dll") 
LoadPlugin("C:\encoding\blockbuster.dll") 
LoadPlugin("C:\encoding\legalclip.dll") 
LoadPlugin("C:\encoding\sampler.dll") 
LoadPlugin("C:\encoding\dustv5.dll") 
LoadPlugin("C:\encoding\temporalcleanerold.dll")

Mpeg2Source("K:\S1M0NE_WS\VIDEO_TS\simone.d2v")
LegalClip() 
GripCrop( width=528, height=480, overscan=2 ) 
GripSize() 
SpaceDust()
TemporalCleaner()
Blockbuster(method="noise", variance=.3, seed=1 ) 
GripBorders() 
LegalClip() 
Sampler(length=24)

## MPEG size = ((Total frames/MovieTimeInMinutes)/24) * MPEG sample file size * .98 ##

If you want a sharper picture, you can try GripSize(resizer = "Lanczosresize")

i "think" this is the last Kwag's script:

LoadPlugin("C:\encoding\mpeg2dec.dll")
LoadPlugin("C:\encoding\GripFit_preview.dll")
LoadPlugin("C:\encoding\blockbuster.dll")
LoadPlugin("C:\encoding\legalclip.dll")
LoadPlugin("C:\encoding\sampler.dll")
LoadPlugin("C:\encoding\dustv5.dll")
LoadPlugin("C:\encoding\temporalcleanerold.dll")

Mpeg2Source("x:\xxx\VIDEO_TS\xxx.d2v")
LegalClip()
GripCrop( width=528, height=480, overscan=2 )
GripSize()
SpaceDust()
TemporalCleaner()
Blockbuster(method="noise", variance=.4, seed=1)
GripBorders()
LegalClip()
Sampler(length=24)

ok?

oops....... hello Kwag.....
i'm posting with you again!!!
