All tx3g subtitle formats in mp4 files appear flat

Italic and other custom lines of timed text tx3g subtitles in mp4 files appear flat. QT shows correct but Infuse shows them all as a straight line (bold, italic does not distinguish)

Infuse

Is there anyone who can be interested?

I wonder if no one can look. I think it will take more than 6 months to solve this problem. Infuse is unfortunately very weak and slow in solving errors.

This is what I get on your sample in Infuse when I set the advanced subtitle settings to

Size = Tinier
Background = 50%

I see it’s not italics but not sure about subs since I don’t use them often.

I don’t see the tx3g subs listed on the available types of subs on the features page. Are they known by any other name?

Okay, just found this suggestion thread requesting that tx3g subs support italics.

I understand. It is a bug that an italic subtitle is not italic. I couldn’t understand that it was a suggestion. It is a bug that clearly italics cannot display rows.

This needs to be fixed. Please help.
