Fluxsmooth+blockbuster quality problem
 

Hi,

In several attemps to encode a movie with LBR template and using BB and Flux filters, the result had too many mosquito noise in high contrast areas, thing that never happened when I used the temporalsmooth filter alone in the same resolution :cry: (in the same kind of source), the source is a TV capture. Here is my script:

LoadPlugin("C:\PROGRA~1\DVD2SVCD\MPEG2Dec\mpeg2dec .dll")
LoadPlugin("C:\Program Files\DVD2SVCD\InverseTelecine\Donald Graft\decomb.dll")
LoadPlugin("C:\Program Files\DVD2SVCD\Fluxsmooth\Fluxsmooth.dll")
LoadPlugin("C:\Program Files\DVD2SVCD\Blockbuster\Blockbuster.dll")
LoadPlugin("C:\Program Files\DVD2SVCD\LegalClip\LegalClip.dll")
SegmentedAviSource("D:\captura.00.avi")
#
ConvertToYUY2()
#
LegalClip()
#
fielddeinterlace(blend=false)
BilinearResize(336,240,8,0,336,480)
#
FluxSmooth(temporal_threshold=7, spatial_threshold=7)
#
# ------ Auto Strength, proportional strength depending on resolution ------
## Remove only one "#" on front of the resolution that matches your encoding.
#
BB_Resolution = 352*240
#BB_Resolution = 352*480
#BB_Resolution = 528*480
#BB_Resolution = 544*480
#BB_Resolution = 704x480
#
BB_StrengthConstant = 352 * 240 * 20 # Base strength
StrengthValue = round(BB_StrengthConstant / BB_Resolution)
Blockbuster( method="noise", detail_min=1, detail_max=10, variance=1 )
Blockbuster( method="sharpen", detail_min=20, detail_max=90, strength=StrengthValue )
#
# -------------------- End Auto Strength ----------------
AddBorders(8,0,8,16)
LegalClip()
ConvertToRGB24()

Is there anything that Im doing wrong with my script:?: THX!!

I have noticed that too.
But my source is DVD Rip and I'm using 352x480 resolution.
Some parts are great, but others have many (many) mosquitos. :(
I think the reason could be we are applying too much sharp...
The scenes are not high action, but I noticed that it most occurred with scenes that have white and bright backgrounds.
Hey kwag, did you try the filters with a resolution above 352x240?

Another example
 

This effect also happens in the lobby scene of The Matrix, lots of mosquito noise around the policemans white shirts and in the green marble of the floor... It is far better to me in this scene, for example, the Temporalsmoother+unfilter conbination

Any suggestion :cry: :cry: ??

Re: Another example
 

Happens to my copy of Matrix too, and I get a lot of ringing in that scene also.
A REAL bad one, is the one where Neo sez: "Guns..lots of guns" scene,
and they all slide out and he talks to Trinity.

Another observation....
When I use "Motion estimate search" instead of "Highest quality" on
tests of those scenes, there is a noticeable drop in ringing AND artifacts,
in those scenes....Hmmmm....strange!... :?

mmmmmmmm I will try... Kwag, Sansgrip or anther expert need your opinion or advice :wink:

We're currently working on ways to reduce mosquito noise, but what might work for the moment is reducing the amount of noise you add to the clip. It'll make the DCT blocks more visible, but it should also reduce the mosquito noise. I'm afraid at the moment we can't get rid of both :).
