what kind of filtering is it ?

@All
The question come up in the process of testing LiveForIt's UAE changes, when i test AGA demos.

Elude group (ex MadWizzards from the past), make a demo 10 years ago called "We come in peace", and that was the demo i test it few time while LiveForIt upgrading our UAE.

I start to check Youtube just to see how it was on original amigas, and find out something interesting.

See this version (original look, and the same as i have on our UAE too):



And see this version (seems some filters used):



On our UAE i have first variant now, so everything blocky-pixels, etc as we may expect from the 320x256 resolution or how it was, but low enough.

Then on second video it looks clear much-much better and more real.

What i want to know, is what kind of the filter were used there. As probably it was WinUAE used with some filters applied, IMHO. But correct me plz if i wrong, and this is something else. Or, if you know what kind of filter it is (and if it WinUAE at all), speak up as well please

Thanks!
