Blocky noise problem...

MiyaDV · Post by **MiyaDV** » Tue Jan 22, 2008 5:49 pm

Ermm.. I've tried like everything to get it to go away, it's really bothering me lol (I have the same problem on Samurai X footage)

Right there in the middle of her cheek lol, and right around that lil ball of light thingy, You can't really see it too well, but durring motion it constantly moves and changes..

any idea how to fix that? heres the uhm script

Code: Select all

mpeg2source("C:\Documents and Settings\Owner\Desktop\ANIMU\VTS_06_3.d2v")
deint = TDeint(mode=2, mtnmode=3, blim=100)
TFM(cthresh=4, slow=2, clip2=deint)
TDecimate(mode=1) 
Deen("a3d",4,7,9)
Tweak(sat=1.1)
Crop(8, 0, -8, -0)
LanczosResize(704, 400)

Try the TTempsmooth() filter.
If you don't have it, you can grab it here: http://web.missouri.edu/~kes25c/

Also, virtualdub may be set to only display 16bit color, which can make what you see in virtualdub look considerably worse than what the video actually looks like. Check it out in a media player or your editing program as well.

I tried it out and it did help abit, it stopped it from going everywhere and stuff but it's still there grr (I want everything to look like the Haruhi DVDs lol)

Here's a little pack if you wanna look it over,
http://donut.x-fps.com/umg.rar

Theres
Deen.avi =

Code: Select all

tweak(sat=1.1)
Deen("a3d",4,7,9)

Deen+Temp.avi =

Code: Select all

tweak(sat=1.1)
Deen("a3d",4,7,9)
TTempSmooth(maxr=5, lthresh=7, cthresh=8, lmdiff=4, cmdiff=6, strength=5, fp=true, vis_blur=0)

Original(deinterlaced_.avi =

Code: Select all

mpeg2source("C:\Documents and Settings\Owner\Desktop\ANIMU\VTS_02_1.d2v")
deint = TDeint(mode=2, mtnmode=3, blim=100)
TFM(cthresh=4, slow=2, clip2=deint)
TDecimate(mode=1) 
Crop(4, 4, -4, -4)
LanczosResize(704, 384)

I don't think Deen is working properly or something.., I haven't had this problem before. Deen would always clean all the fuzz.
In the original theres normal fuzz, then when I add Deen it turns to crackly fuzz, then I'm adding that TTempsmooth() to fix the crackly fuzz that Deen caused lol

I guess it's not so bad, but I just really want to remove that lol

btw, that TTempsmooth filter is scary when you set the thresh's to 100 xD

I honestly cant see any noise in the filtered clip. Are you using an LCD monitor? Sometimes those can make noise more apparent in the video.

There's not much you can do for that. The whole picture is covered in fluctuating noise. If you remove it all you will just reveal moving DCT blocks and banding.

Maybe motion compensated temporal denoising would be the best place to start.

I do use a LCD monitor, but haven't had this issue before, or I wasn't aware of it.

Thanks for the help guys, it's not too much of a problem I'll just work with it lol

Also thanks for that TTempsmooth filter, I really need to go download some other ones and see how well they work, I've always used the ones that came with AVS / AMVAPP.
