Hey everyone! I need to make my sub an EBU-TT-D 1.0 (Tech-3380) .xml. With Subtitle Edit I can save it as a Timed Text 1.0 .xml and I think it's kind of what I'm looking for, but not exactly the same.

I don't know how to code and don't understand even a line of Phyton. I tried following the BBC's "easy" instructions to make an EBU-TT-D, but don't understand them. I need some way of saving it directly like that or converting it with a free tool. Please help!

Thanks in advance!
