The graphics chips on the dedicated 24bit video cards are usually MUCH more powerful than a M68030 (TI 34020?) and is clocked much faster as well. >It was interesting though, that the frame rate slowed down >considerably when any kind of mirroring or colour adjustments were made >(on the fly). -stuff deleted- That "real live FX" that you spoke of was being 'helped' by some pretty expensive video cards and laserdisk players. QuickTime is a part of Mac OS 7.1. It is SOFTWARE/STANDARDS that will be able to run on every MAC that has that software in it. Nowhere did Apple say hardware (laserdisk,24bit boards, etc.). I have seen/worked with QuickTime and can tell you that as soon as you get larger than that small 180 pixel screen, "IT SLOWS DOWN CONSIDERABLY!". There is nothing "close to TV" about it. Even on an FX! -- William "Art" Warner //\ CBM Amiga Student Rep. \X/--\miga makes it happen.......... wwarner@en.ecn.purdue.edu IBM, Apple, Sun, & Next make it expensive!
