I know there are a lot of documented issues about blurry text and titles after rendering. I am encountering blurry titles within the Titler interface, and on the timeline in Premiere Pro CS6. It is just white text on a black background, nothing has been scaled up or transformed or anyway, but the text is just totally crappy looking. It will probably look ok when you look at the small screenshot cap below, but if you look at it at 100%, you can see that the text is blurry and there are broken horizonal lines.
Perhaps it will render out ok, but I'm still mystefied why Adobe would put out such a sub-par program.
