Need help filtering Jaggies

[LadyLiete]

Does anyone know a filter specifically for this? I have encodes for a cartoon that I want to fix. They are otherwise good quality but suffer from jaggies in certain scenes. I was wondering if there was a way to get rid of them. I don't have the original source, so basically this is what I have to work with.

Here is an example: http://www.freeimagehosting.net/newuploads/uzhgf.jpg

Any suggestions?

They are very hard to ameliorate. It's best not to get them in the first place. IVTC film sources. Use a better deinterlacer (if you really need to deinterlace). If your source has already been deinterlaced like that try to find a better source.

As a last resort try nnedi3_rpow2() in AviSynth. Before and after:

ImageSource("uzhgf.jpg") 

SeparateFields()
SelectOdd() # keep the better one

nnedi3_rpow2(2, cshift="BicubicResize", fwidth=640, fheight=480)

You'll still have some buzzing edges when in motion.

A better example would be some of the video. But as jagabo mentioned, if some idiot has already wrecked it, trying to find a better source is the best solution. You might even (gasp!) buy the DVD if you like it so much.

Thanks. Does this only work on avi? What code would be needed for video?

I'm a bit confused on how to use this program.

If a complete dvd existed I would.

AVI is video, last time I worked with one (the 3 letters stand for Audio Video Interleave). If all this seems completely unfamiliar, you might want to see some of the many samples on this page: http://www.animemusicvideos.org/guides/avtech31/post-qual.html

If that looks too advanced, try starting at AMV's main guide: http://www.animemusicvideos.org/guides/avtech31/

Most of us here have the same problem.

I have the .avs text file open, but I don't know what to type in to get it to filter the video the way he did with that image. I'm kind of dumb when it comes to this kind of stuff. The file resolution is 640 x 480.

Download and install AviSynth.

Download nnedi3.
http://web.missouri.edu/~kes25c/nnedi3.zip
http://web.missouri.edu/~kes25c/
Extract nnedi3.dll and put it in AviSynth's plugins folder. Might as well put the readme there too.

Create a text file with Notepad (or any other plain text editor) and make a script like:

AviSource("filename.avi") 
SeparateFields()
SelectOdd() # keep the better one
nnedi3_rpow2(2, cshift="BicubicResize", fwidth=640, fheight=480)

Change "filename.avi" to the appropriate name for your AVI file. Save that file in the same folder as the AVI file -- but change the extension from .TXT to .AVS.

Open that AVS script in an editor encoder that supports AviSynth scripts.

Encode.

Thanks so much!

By the way, I recommend using VirtualDub to view the results of your scripts.

[LadyLiete]

Okay ill do that.

[jagabo]

Oh, and because many people get confused, in VirtualDub use File -> Open Video File to open the AVS script, not File -> Run Script.

[LadyLiete]

I got it working, also downloaded Simple x264 Launcher to recode the videos. It takes a while to encode them but I have seen a definite improvement in the episodes, the jaggies are vastly reduced

[jagabo]

Glad it worked for you. If a video looks blurry try changing SelectOdd() to SelectEven(). Odd was better with the sample image but even may look better with some videos.
