Two lines. I made a better one later with smoother transition and shorter lines. But overall I’m going to give up on this. It takes a lot of work to achieve the effect that I want and it’s a really hard tool to use without knowing some programming language. There’s just no way that I’ll be able to figure out how to add furigana to the karaoke subtitles so I’ll pass.
It was fun to play with though and it is free :)
