I would have to redo all my texts cards! NooOOoo

Well if you'd be interested TMBTM, I'd be willing to lend a hand for things like this and I'm sure that others may well be. Might i also suggest adding the name of the person speaking to cards? - you could do the names in grey and the dialogue in white.

That might be handy for scenes like the end of TPM where yoda and mace both speak quickly and you cut to a dialogue card showing Mace's dialogue before we've even seen his mouth move...it could be assumed that all dialogue shown could be attributed to the one character, Yoda.

even cropping the video to a full frame 16:9 ratio may help give it an 'old' style.
