MeGUI - video output pixelated

Hello everyone!

I was wondering if there was a way to re-encode anime to a smaller file size (80mb perhaps? / 400-500 bitrate?) without the output being pixelated?

In my output the pixelation is very noticeable specially on:
• Dark Scenes
• Raining/Foggy Scenes
• Fast motion scenes (sometimes)
• Dark colored parts
Here is an example:




(there are much worse scenes than these)

I've seen many animes from various encoders whose outputs are not pixelated at all but just a bit of blur (not really noticeable) and the filesize is around 60-80mb!

is there a trick behind this?

I'm using MeGUI by the way and here are my encoder settings preset:
Video Encoder Settings: x264: DXVA HD-Anime_Toons HQ
Audio Encoder Settings: Nero AAC: NDAAC-HEPS-32kbps

No. Ok, I don't like the idea at all. Why would you do this?

Make sure you start with your original DVD, bluray, or TV capture; recompressing an already compressed source will give lower quality. I assume by "pixelation" you mean macroblocking not a bad resize or some other type of pixelation?

There are all sorts of ways to get it looking different, most involving Avisynth. Have you tried playing with the --nr option in x264? Also resizing to a lower resolution helps with lower bitrates.

i'm not really good with the codes used in avisynth
mind helping me?

also i added an image about the pixelation thing... see if its the same thing as what you meant.

thanks for the responding
