Well, judging from the 35mm scan, they are still not fat enough and I don't think that this has much to do with it being a print - making them a bit less blurry may be a good idea though - it's just that when they are too sharp, they start looking digital, so I'm convinced, that some amount of blurring is necessary.

But yeah, that fading effect got all screwed up by the matte choker effect, so I had to let it go - I might still try a different approach.

Are you, by any chance, using the wrong composition from my project? "TESB Credits Comp" would be the right one, and it already has a "Roughen Edges" filter on the text for the blurring.

If you're using that comp, you could just insert a slight "Fast Blur" after the "Roughen Edges", then a "Levels" correction after that, affecting the alpha channel to adjust the blur. This would keep the color change during fades intact.
