Need help with bad aliasing

[MysticFTW]

I'm trying to encode aqua teen hunger force dvds but the lines are jagged normally I would use daa for aliasing but it seems to have little to no effect on this, I've tried everything I can think of but nothing works.
Any help would be greatly appreciated.

This thing was encoded as progressive? This is direct from a retail DVD?

[MysticFTW]

Yes it's progressive and yes direct remux from DVD

I'd ask for a refund.
There are a few ragged lines, maybe drawn that way, but very little buzzy aliasing and it's not consistent.

[MysticFTW]

Is it fixable completely or at least partially?
Also I've had these for awhile just really got around to encoding them until so I can't get a refund.

Maybe you should tell us what you mean by encoded. They're DVD, so they're already encoded as MPEG2. I think you mean that if you want to work on the supposed aliasing, you need to decode them into unencoded video, filter them, and re-encode them again. Encode them to what format? You realize that there will be some quality loss through the re-processing. The amount depends on how it's done.

And don't convert to mkv from DVD in order to do this. Use DGindex to make your work copy directly from the DVD or use VOB2MPG to extract the video and audio from the original DVD disc -- or use any of several other ways of getting there, but converting to mkv first is kinda silly..

I didn't convert it to mkv, I used makemkv to remux the DVD to mkv.
How would generating a d2v file make a difference either way its the same file when opened in megui
By encoding I mean encoding the remuxed mkv with megui
Yes I understand there will be a bit of quality loss

Ok I generated a d2v from the raw video.
So what should I use to clean up the aliasing?
I've used daa and Maa neither work on this source

[LMotlow]

I suggest Santiag v1.6 (http://avisynth.nl/index.php/Santiag).
Try this, it worked tolerably well on your mkv and smoothed most of the sawtooth edges (the example uses your mkv):

aud = ffaudiosource("path\to\Aqua Teen Hunger Force Forever_sample.mkv")
vid = ffvideosource("path\to\Aqua Teen Hunger Force Forever_sample.mkv")
audiodub(vid,aud)
santiag(strv=4,strh=4,type="nnedi3")
return last

To use your d2v, try this (for the AC3 output file you can use the NicAudio plugin from http://avisynth.nl/index.php/NicAudio):

aud = NicAC3Source"path\to\AudioFile.AC3", channels=2)
vid = MPEG2Source("path\to\VideoFile.d2v")
audiodub(vid,aud)
santiag(strv=4,strh=4,type="nnedi3")
return last

There are other methods, but getting stronger and more complicated means more blur and loss of crispness. You can't have everything.

Ok I generated a d2v from the raw video.

The point is - when providing a sample - to upload the M2V and not an MKV which makes more work for those trying to help. You generate the M2V by using the [ and ] buttons in DGIndex to isolate a small section followed by File->Save Project and Demux Video. That gets you a D2V project file you can toss, the audio you can toss, and an M2V you upload here.

Nvm I got working.

[MysticFTW]

Thank you Santiag worked great.

I'm having the exact same problem with these dvds. Can you post your script?

I get the best results using santiag with qtgmc fast preset, but it just creates new issues that ruin other parts of the video. I'm starting to think its best to just leave the aliasing alone.

I just used what LMotlow suggested as a base but I ended up changing it slightly to get a better result.
I don't have the script since I've had to stop working on them because my motherboard is fried (2yr old spilled water on it ☹️).
If you manage to get better results please let me know.
