Maybe it says "Hi Quality" because it's meant as a salute? Like, "Bye, quality?"
But really. Super is a Very Bad converter, and you should Read ErMaC & AbsoluteDestiny's Friendly AMV Guides Lovingly Overhauled Largely by Zarxrax
to learn how to convert properly.
Most specifically, you should not use wmv as files to import in your editor: the quality will get lowered by a notch, and since it's lossy, editing won't be the most comfortable and accurate either.
We generally suggest doing lossless clips, possibly using utvideo as the codec, by using a combo of avisynth+virtualdub. But again, in the guide I already linked, everything is explained.
