Animation XviD to x264

[pub]

I want to encode some old XviD encodes with x264, but I noticed some artifacts like dot crawl, ringing, grain and ghosting (probably because of the deinterlacer I used back then). This looks like it clean up most of it:

ffVideoSource("clip.mkv")
Cnr2()
MCTemporalDenoise(settings="medium", AA=true, edgeclean=true, useTTmpSm=true)
TemporalDegrain(HQ=2)
AwarpSharp2(depth=5)
Toon(strength=0.8)
LSFMod(defaults="slow", strength=140)

x264.exe --profile high --level 3.1 --preset veryslow --crf 17 --tune animation --output clipoutput.mkv cliptest.avs

I'm not sure if they're in the right order and it seems that some chroma noise is still left or somehow uncovered because of the degraining. Also, I can't get rid of the ghosting. It looks like it's still interlaced but a bit faded away. Am I doing something wrong with this script/what should be added to get rid of the ghosting?

You need to post a sample of the source that's not reencoded. Include shots which show the problems and a longish medium speed panning shot.

chroma.mkv
After using my script (or any other strong degrainer/denoiser I've used), the background color gray somehow flickers (the red boxed area). This isn't very noticable on my computer, but it is very on any other device (lcd tv, crt tv, laptop, tablet, phone). Looks like Cnr2 reduces the flickering a bit, but not ideal.


lines.mkv
In this frame, there are some lines in the middle of the screen (see the red box). QTGMC didn't get rid of it.


morelines.mkv
When speaking, this sometimes happens. Again, QTGMC didn't get rid of it.


movement+chroma.mkv
These artifacts occur during movement.



And the background flickers again, like with chroma.mkv. It looks again like Cnr2 reduces the flickering.


And the entire video has some what looks to be unsharp edges if the edge isn't black and grain.

Unfortunately the video was resized and compressed with those comb artifacts so they will be hard to remove completely. You'd be better of going back to the original source. But if this is all you have a sequence like this reduces them quite a bit:

BicubicResize(720,480) # back to the original frame height
TFM(order=0, mode=5, slow=2, cthresh=9, blockx=8, blocky=8) # TFM again with more sensitive settings
vInverse() # reduce combing in remaining ghosts
BicubicResize(720,544) # back to the starting frame size

You might also try using a mask to overlay the fixed video in areas where comb artifacts appear. That would protect the rest of the image from resizing artifacts.

Those TFM() settings should also work better if you go back to the original source.

Thanks, looks like it worked!
