Hi all, I'm using Subtitle Edit on Windows. I have two .stl subtitle files for the same video - one is exported as EBU STL open subtitling, one is exported as EBU STL teletext with "double height for text" activated.

My client wants me to deliver these two subtitle tracks as one mixed mode .xif file. Whenever I try to merge the two files (Tools > Join subtitles), the teletext properties are lost and I just have a .xif file with all open titles.

I have also tried exporting both as .xif and then merging, but still the closed captioning turns into open subtitling.

Any way to mitigate this with Subtitle Edit or any other software?

Thanks.
