I edited a movie in final cut its about an hour long and has a lot of text in it i just found a new font i want to use is there an easier way to change all of the fonts at once, than just doing each one individually?
It's a little fiddly, but essentially you export an xml of a timeline with a single sample title in the font+style that you want to change everything to. With that xml you create a template in Title Exchange Pro.
Then export all your subtitles on one track as an xml, and use TEP to convert the xml, to an xml, but using the template you created. That will change the font - and any of the parameters in the text generator - of all the subtitles. Then reimport the new xml into FCP.
