Filter to remove this noise

[towerblocks]

Hi

I'm currently backing up some of my dvds to XviD,But most of the time i end with this type of noise wavey lines http://www.savefile.com/filehost/files.php?fid=4041032 <--sample,It's most visible on the brown part of the ramp by where the guy is lying,What filter should i use to remove this and what's this type of noise called.

Thanks

What noise do you mean. The pictures look really smooth and flat for me. Or do you mean the edge enhancement on the ramp. Was it interlaced before, a better interlacer can solve this probleme. What resizer you use, best is using lanczos. If you want a softer look just use parameter like 0,-0.5 or so. Maybe blinddehalo3 could also help for this case. Or is there a type of noise I can´t see?

Thanks for the reply,Yes the source is interlaced i used Seperatefields() Selectodd() then resized to 640x272 with lancozs,Maybe it shows up more on my crap monitor hehe,But the more i sharpen the video the worst it gets.

provide the original VOB instead of the already filtered one!

Use tdeint with the ela algo (type=3, I think) or just try leakkerneldeint (much faster) to deinterlace and then rezise the movie, this should be a better solution. Tdeint should work better.

this looks like 'reservoir dogs' although I've never seen this film.
So I thuink it is progressive, so deinterlacing is nonsense!

to use telecide or tfm will be the best choice.

Good guess, scharfi. It's Reservoir Dogs. And, like you, I also don't believe it to be interlaced.

Yes the source is interlaced

How do you know that? Did you just get that information from DGIndex (which tells how it was encoded, and not whether or not the source is really interlaced), or have you seen actual combing? If you've seen combing, then most likely it has shifted fields, and, again, as scharfi said, either Telecide or TFM should be able to fix it up.

Hey Towerblocks, post that same clip after you process it so we can see the changes. :)

DGindex preview showed it as interlaced,I'm not an interlacing expert has you can see has i thought it was noise,I did try Seperatefields().Weave and it seems to have eliminated the problem, Or maybe it's the wrong way to go about it im not sure? ,I've included 2 sample's first encoded with Seperatefields().weave and second is the original vob.

separatefields().weave() is nonsense, because it does nothing except wasting CPU-time!

the result will be still the same (bit-identical!) without separatefields().weave() !

dgindex says interlaced, because the encoding-scheme is interlaced, but the video-content is still progressive!

[scharfis_brain]

this script will be fully sufficient (WITHOUT any deinterlacing!):

640x264 pixels:

mpeg2source("blah.d2v")
lanczosresize(640,264,2,72,718,432)

OR
704x296 pixels:

mpeg2source("blah.d2v")
lanczosresize(704,296,8,72,704,432)
