Framestor encodes suck anyway; despite the massive size of their releases, they still have not found a way to prevent hideous pixelation, banding, smearing, and a ton of other artifacts. Flawl3ss tends to over-sharpen theirs. Eureka, despite their encoder being a total egomaniac and a general dick, still produces the best quality encodes.
The above is not merely an opinion but indisputable fact.
