Hello. I am using opera and i can download subtitle using your work. But timing is wrong. I take vtt file and i check, timing different your script then original. Because in your script, the duration of one subtitle line is extended to the beginning of the other subtitle line. It doesn't end in the time it should be. That's why it is displayed too long.

Thanks for the feedback!
