Chinese Closed Captions - Help Needed!!

Hi Guys,

I need some major help please. I have played around with FCPX for home stuff and now started editing a few things for work, nothing fancy at all. I have been asked by my work if I can add Chinese subtitles to an existing company video.

What I am trying to do, is add multiple languages as closed captions so that our English sales people can go out in the field, run the video in front of a customer and if required select the appropriate closed caption.

I cannot for the life of me work out how to export the movie with these captions embedded. I also cannot get the captions to work in CEA-608 format. If I select CEA-608, Simplified Chinese, Create a Caption and then cut and paste my translated text from a xls file the caption box is red. Is this due to the language being used?

Any advice or guidance would be great.

Thanks

Paul
