Has anyone else noticed that the dithering in QT4 is not as good as QT3. For example, my desktop pic used to look good using only 16bit color under QT3, but after I installed QT4 there were fairly distinct blocks of color. Bit of a pain.

That's what I tended to notice when using QT4 too.

Mind you I don't exactly have the most lightning fast Mac in the world (5500/225). It's particularly noticable with movies that are particularly processor intensive (ie the Starwars trailer). While QT4 has improve the frame rate slightly and has made it a little less jerky I've noticed that the trailer becomes more grainy when you try to play the movie at douible size etc.

Oh well can't have your cake and eat it too.

I have definitely noticed this too - both on a 6500/225 AND a PowerBook G3 - so it's not tied to processor speed.

The StarWars trailer (25mb version) now seems pixelated while running at thousands of colors, which did not happen with QT3. Also, when I grow the window a bit, the movie looks even more blocky and pixelated, which didn't happen under QT3 either.

Looks like they've tweaked the Sorenson codec a bit? And not for the better. I'm not getting more performance out of it, just uglier.
