Huh, I'd just use Aegisub/TextSub/Avisynth for that. o.o;

Just to clarify, the hard part is not the compositing of the text, it's making a clean plate in HD using the regraded bluray and a "patch" from the textless dvd release. Which is what I've been doing so far. It's not perfect yet, the patch still needs stabilizing, it doesn't look good in motion, but it's a step in the right direction I think.

Besides, as powerful as Aegisub is (I've used it) I'm not sure how feasible simulating gate weave on it would be. I'm guessing not very. The intent of this project is to try and recreate the italian version, and that entails making it look as authentic as possible, gate weave included. I'm not talking huge amounts, but it will be there, it has to be there to help "sell" the effect.
