:D

I have made good experiences with xlogo

If the Logo partly overlaps into the border, i've used a litte skript:

Code:

LoadPlugin("d:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\MPEG2Dec3.dll") 

LoadPlugin("d:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\UnDot.dll") 

LoadPlugin("d:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\BlockBuster.dll") 

LoadPlugin("d:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\xlogo.dll") 

LoadPlugin("d:\PROGRA~1\DVD2SVCD\AVISYN~1.5PL\asharp.dll") 

#open Source 

clip=MPEG2Source("o:\24_2_15Uhr.d2v") 

wav=MPASource("o:\24_2_15Uhr MPA T01 DELAY -564ms.mpa") 

clip=AudioDub(clip,wav) 



#cut out commercials 

clip1=clip.trim(0,13672)+clip.trim(24046,36859)+clip.trim(37331,45804)+clip.trim(48497,61831)+clip.trim(62432,74910) 

clip=clip1 



#Denoise 

clip=clip.Undot() 

clip=clip.TemporalSoften(3,10,12,15,2) 

clip=clip.Asharp(1,3) 



# tricky Xlogo 

clip=clip.ConvertToRGB32 

mirr=clip.Crop(596,445,74,54) 

mirr=mirr.FlipVertical()    

clip=clip.Layer(mirr,"add",255,596,499,0,true) 

clip=clip.XLogo("o:\Logo_RTL2_x_606_y_455_2.bmp",606,455,0) 



# Blockbuster 

clip=clip.ConvertToYV12 

clip=clip.Blockbuster(method="noise",detail_min=1,detail_max=10,variance=0.3,seed=5823) 



#trim to 704x576 

clip=clip.Crop(8,72,704,428) 

clip=clip.AddBorders (0,74,0,74) 

clip=clip.letterbox(16,16,16,16) 

return (clip)

the "Logo_RTL2_x_606_y_455_2.bmp":

I have vertically reflected the range of the logo (and a little more around), which was in the picture, and inserted it into the black range below the logo.So no parts of the black border where blurred into the picture.

You can find a little (german) Workshop here:

If the logo is semi-transparent you can try NoLogo. Pretty simle to use but takes some tweaking to get working. (http://www.kvcd.net/forum/viewtopic....ghlight=nologo)

If the logo is solid, MSU has some VDUB filters that seem to produce some impressive results:

There is a "nologo" filter also in ffdshow now. If you want to try some parameters before to implement it into a script.

@Dialhot

I downloaded ffdshow from the project page but I cannot find any information about a logo filter. Could you provide a link?

The Logoaway FIlter from ffdshow is a simple 1:1 port of Vdubs logoaway - easy to use and a simple anti-logo-interpolation, means qick'n dirty.

The Filters in ffdshow can be set in the decoding section. Or when doing encoding, then in the "input" section.

:wink:

how do you know if the msu logo remover has worked? I try to r=preview in v/dub after loading it and it still shows.
