I use Word, and WordPerfect for Titles, but am more often creating those in Photoshop, for Import into PrPro.
I use the Copy/Paste method, but as the formatting is code, specific to the wordprocessing program, do not bother even doing that, in Word/WordPerfect, and do it in PS. The same hold for PrPro.
I know of no way to get the formatting code to be read in either Photoshop, or PrPro.
Good luck, and maybe others have a neat trick - then we can both learn something.
I thought I used to be able to copy out of Word and paste into AE and retain the formatting but that doesn't work anymore, if it did. I'm a little foggy on if that was Word to AE or AI to AE.
One problem with the Premiere titler I can't seem to figure out is if I have a very long block of text, there seems to be no way to scroll down in the titler window. Am I missing something?
Now, AI to AE, or PrPro will be different.
Personally, I liked the Rasterization with PS, from AI, better than PrPro, but have not tried it out in PrPro CS5.5, so that might have improved.
