MeGUI is also ABANDONED BY ITS OWN DEVELOPER AND DOESN'T SUPPORT HALF THE NEWER THINGS IN x264 THAT ZARXGUI DOES. If you want a full featured x264 GUI, you should be looking at sx264. Otherwise stick to CLI like a man (it's actually easier than GUI once you learn the presets) or just use Zarx.

sorry for digging up old threads but i thouhgt it was senslseess to create one for one scene : p
http://i51.tinypic.com/1zwkcjt.png there is it upscaled Last Exile but that's literally the only scene that annoys me -blocky heaven and i can't get rid of it : P deblockers dont like me , or something (need an update of avisynth...i guess-can't load i.e. deblock qed) but some hint might be uselful it looks even more horrible when it moves : p

On the screen of the netbook I'm on atm I can only see banding, not blocking (there might be some and this screen might just suck enough to not show it). I'd say check the avtech 3.1's avisynth filters section, there's a part about debanding.

I also only see banding. It's so blurry it's difficult to notice though.

sorry about bluriness maybe it'd because i set high denoise on my graphic card : p
i was pretty sure it's some weird lively blocking (since it looks like blocks-but it shows up where the color is a bit changing to darker)
anyway i will seedebeanding helps ty:o

I'm positive the blurriness is due to the upscale, actually, but since you'll be making the vid at SD res (RIIIIIIIIGHT?) it's fine. :P

50 is BATSHIT INSANE, did you even read the suggestion of the guide on the filter's usage? Going over 2 will be already too much with most sources and most likely a detail killer in any case!
Anyway, give blockbuster a chance (try to call it as blockbuster("noise") and if that doesn't work, check the readme). And don't forget to scale back to 480p since it's just an upscale, I think that might actually help out ─ I'd say call blockbuster("noise") before the resize and gradfun2dbmod(1.05) after.

heh okey after render it looks a tad better with gradfun and some deblock at least it's not moving that much and looks more like white thing which is kinda acceptable (i guess puting there some keyframe and replacing it with gradient/or clouds would be much faster tho : p) but yeah in worst case somebody will slain me :uhoh: :dino:

I'm just going to point out that a debander adds dither. This is what causes banding in the first place. Throwing a lot of dither and then compressing it gives you even MORE banding, hence why 50 didn't work.
