Dehaloing would definitely be a good idea. [/suggestion]

But since I have no idea what to do with such sources, that's about all I can say.

[Lyris]

There's not a lot you can do with that. Fortunately it's quite untextured so FFT3DFilter / FFT3DGPU to reduce the appearance of the compression artefacts shouldn't chomp through many genuine details.

Thanks for the help...
Ok, I'm using the script below and display error massage:
Script:

Avisource("oSerendipity.avi")
FFT3DFilter(sigma=2, sharpen=0.3, interlaced=true)

Error Massage:

Avisynth error: YV12 images for output must have a width divisible by 4 (use crop)!

How to fix this error. please ?!

[Lyris]

The frame size is 768 x 576, and it needs to be divisible by 4. So before FFT3D I would add:

bilinearResize(720,576)

Normally I don't like the idea of scaling, but this looks like it's been horizontally rescaled anyway, and scaling isn't really going to do any damage to this.

You might also want to have a look for SremoveDirtMC and add that in after FFT3D to take care of the dirt and scratches. The animation is quite limited so I doubt it will do harm to genuine details.

[FlaShow]

Thanks Lyris. Is it possible to provide a link for SremoveDirtMC filter. please ?!

Have a look here FlaShow : http://forum.doom9.org/showthread.php?t=134078

@FlaShow,

There is a search option at the top of the page (on sky blue bar) but it cannot find text in code sections,
but the below would even find it in code via google:

SremoveDirtMC Site:forum.doom9.org

[FlaShow]

Thanks StainlessS for the info & the only thing i found is RemoveDirt filter...?!

EDIT: You par Ruski (In a Sean Connery accent).

EDIT: Funny, google did not find this link, removeDirt, but see script in 2nd post.

Yes it can.

[StainlessS]

Did not used to do it (i've had trouble in past where it would not find in code, maybe they fixed it).

(can you take a look at ColorYUV2, just posted please).

[FlaShow]

Thanks StainlessS,
I put the script to an avsi file with the name of SRemoveDirtMC.avsi but when i call it with SRemoveDirtMC() it display
Script error: Invalid arguments to function "SRemoveDirtMC"
How should to call this function ?!

Best Regards,
FlaShow

[StainlessS]

Put Double quotes around "limit" in function definition.

EDIT:
As it is, 'limit' is not optional, but inside the function, it treats it as if optional, ie
uses 'Default(limit,6)'

EDIT: Same for RemoveDirt function arg 'limit'.

AVISynth open failure: Script Error: MVAnalyse does not have a named argument "truemotion":

[Bloax]

AFAIK It's on by default, so you can probably remove the "***,truemotion=true,***" parts.

[Didée]

Not good advice. The message about truemotion means that he (resp. that Avisynth) is using a stoneage version of MVTools. (Link leads to actual version...)

[Bloax]

I should sleep less in the middle of the day I guess.

Thanks guys it is work fine now and i got the best result with this script:

Avisource("oSerendipity.avi")
bilinearResize(720,576)
Deblock()
dfttest()
FastLineDarken()
deen("a3d",4,8,9)
Spline36Resize(last.width*2,last.height*2)
AddBorders(4, 0, 4, 0)
aWarpSharp(depth=12,blurlevel=4,thresh=0.2,cm=1)
FastLineDarken()
aWarpSharp(depth=6,blurlevel=4,thresh=0.7,cm=1)
Crop(14,10,-14,-10)
FastLineDarken()
DeHalo_Alpha()
fft3dgpu(bt=3,sigma=8,sharpen=1.3)
Spline36Resize(640,480)
Tweak(sat=1.1, bright=0.0, cont=1.1)
Dup(threshold=4)

Seems like too much filtering, particularly the excessive repeats of aWarpSharp and FastLineDarken. The picture itself does not look that awful. Like others have said, I would recommend halo removal (Dehalo_Alpha and maybe EdgeCleaner too). I would also add line thinning (aWarpSharp, which can also remove minor haloing) and some judicious light denoising (MDegrain if you're up to it, DFTTest if you prefer something simpler but quite effective too).

You might want to have a look at this thread for filter sugestions on a variety of situations.
