Problem Encoding Anime in H264

[Tatsukun]

I'm trying to encode anime for the first time. I'm attempting to use MeGUI with the x264 codec and some avisynth plugins. Occasionally throughout the show, usually only in black or darker colors, boxes appear.

I was wondering if maybe I set something wrong in either the codec settings or maybe if one of the filters I applied in avisynth caused this?

My avisynth script looks like:

Load_Stdcall_Plugin("C:\Program Files\megui\tools\yadif\yadif.dll")
Yadif(order=1)
mergechroma(blur(1.3))

:thanks:

Encoding settings? Source images in addition to pictures of the encode? x264 version?

Sorry my bad...

x264 version is 1057 Skystrife's Patched Build, I think.

Settings for it are: http://img522.imageshack.us/img522/687/settingssd4.th.jpg (http://img522.imageshack.us/img522/687/settingssd4.jpg)

you can just post a command line, by the way.

This, folks, is why disabling AQ on anime is a retarded idea.

lol I think I could have said it more politely, but I agree completely :D. The lack of AQ was the first thing that came to mind, but I refrained from posting as I wasn't completely sure. With super-duper clean, digitally-processed animes with fine edges, it's still nice to have some level of AQ. I usually use 0.2 or 0.3.

Look at the "Advanced" Tab and go to "Adaptive Quantizers." Change it from "Disabled" to something else; I don't have MeGUI handy atm but I bet the last option is probably preferable. Change the strength to 0.2 or 0.3 instead of the default 1.0. Tell us how it turns out :).

Thanks I will definitely try that. I've been reading a lot of tutorials and whatnot but most of them were just for general encoding and not anime specific.

Hopefully this will help =]

Edit:
Thanks turned out great. Fixed that problem perfectly.
