Deinterlace/Restore

[Ryo94]

Hi,

I would like to know which is the best way to deinterlace or restore this scene so that the building and stairs in the background don't don't look so ugly?

Thanks in advance.

Looks like it's standard 3:2 pulldown.

mpeg2source("sample.d2v")
TFM().TDecimate()

should do it.

Thanks for reply Didée, I did what you said,

LoadPlugin("C:\Program Files\StaxRip 1.1.7.0\Applications\AviSynth plugins\Decomb\Decomb.dll")
LoadPlugin("C:\Program Files\StaxRip 1.1.7.0\Applications\DGMPGDec\DGDecode.dll")
LoadPlugin("C:\Program Files\StaxRip 1.1.7.0\Applications\TIVTC\TIVTC.dll")
mpeg2source("C:\sample.d2v")
TFM().TDecimate()
Crop(18,102,-18,-108)
Lanczos4Resize(704,304)

but the results are the same, I mean, the duplicate frames are removed but the background (building and stairs) still looking ugly :(

If you use separatefields() you can see that the that the aliasing is within the fields. Looks like a bad case of hard telecine.

Thanks for reply, do you know any way to fix it or at least improve the scene. I'm now using Telecide (guide=1).Decimate(cycle=5) to remove the dupes and searching in decomb help for a postprocessing line that helps a little, but I had no luck till now.

tdeint(mode=2,mthreshl=2).tdecimate()

Deinterlacing with TDeint makes the aliasing less annoying by blending the fields together, and then decimating with TDecimate brings it down to film rate. It's the only thing I can think of to try to get a decent picture out of it.

Wow, using TDeint improved it a lot the picture, thank a lot ;)

I don't know why but if I use TDeint and TDecimate with 2pass Xvid I get an oversized output file (1.62GB instead the 1.45GB that I set as final size). If I use other deinterlacer like Yadif or Decomb this doesn't happen. Does anybody know any solution for this? Thanks in advance.
