Chihiro: http://i44.tinypic.com/25zqiqb.png
Chihiro encode has less dotcrawl, less noise, smoother lines, better colors, is sharper, and didn't miss 4 pixels of cropping on all 4 sides.
Their video has more character; their colours aren't on steroids (compare shadow colour), but the lines are more 'there' (look at Ritsu's hair line; Mio's hair and jawline), though I daresay their video isn't much filtered at all (besides logoaway or whatever).
You mean their pre-encoded raw they re-encoded. :p Only the japanese have a good filter to get rid of the logos. That's how you can tell that the chihiro is from a transport stream, perfect blue is from a pre-encoded raw.
The lines look like fastlinedarken(thinning=0) with some aliasing from poor h.264 settings from the japanese encoder combined with too low of a bitrate. This raw may have originally been like 140 MB by the looks of it.
FYI, the colors are correct on the chihiro version. It's a SD show, and as such it needs the standard def color matrix applied. If you don't, you get the Perfect Blue colors.
If you like it, then I'm not one to stop you from DLing it. But from my eyes, it has issues.
Their k-timing is off, and their logo bleeds at least 1/2 a second.
Their karaoke timing or effects are a bit slow.. the logo bleeds at scene changes.
It's the timing. You don't time school letter by letter. >.>
Perfect Blue also copied the Chihiro OP lyrics word for word, and at least the ED romaji.
The TL in the OP and ED is quite similar to Chihiro's but not word for word; I don't know If they copied and then modified it. The romaji, I haven't gone over it, but it should be the same for everyone now that the single is out.
I saw the following line in the OP
A "guys forbidden" notebook, a diary bound by love.
This line would never be able to be duplicated by coincidence, as it was here.
ED romaji I could tell because we made a mistake of writing Yaba as Yabai, and they did too.
It was a copy, maybe slightly modified.
