Import TTML with IMSC 1.1 Japanese subtitles to later render with film

Hello!

I need help to correctly hardcode 3 different TTML with IMSC 1.1 subtitle files in Japanese into a film.

Each of the files has different elements, like dialogues, title cards and names, and we need to separate them to avoid overlapping. Some of the titles are located at the bottom center, others are vertical, on the right.

The subtitles are created with Ooona, and I was told that the TTML files support all the Japanese features.

But we are having problems when importing to Premiere, as the positions are not saved correctly.

Can you help if there's a way and format to import directly, without having to manually adjust many lines into the correct position?

Thanks!

Cheers!
