is there a way to add subtitle?

hi im just wondering is there a way to add subtitle to my animation in toon boom that is will link to my audio that work a bit like lip sync instead on writing the text and show an each frame which could be a bit of a pain. ???

There is no other way than using the text tool in TBS. The text does not have to be rewritten on each frame though. If several frames show the same text, the drawing containing the text can be exposed for that duration.

Handbrake is a good one that can add soft/hard subtitles. It’s a total free software.
