The Amber chip based ff's (A3000 & A2320) and the PicassoIV's ff output bright right away, just like normal 15KHz Amiga video modes. I think the PicassoIV's is a little better overall, if I were to judge by picture quality and absence of any visible scan lines, etc. There are three other AA video slot ff/sd's out there for the A4000 (Video Magician, Petsoff's and Power Computing's); they are probably all pretty good and better than the external ff/sd's I've read about.
