We all know that YouTube short only allows 1 minute in length video. And to have 1 minute in length video, the amount of character is only around 900-960 characters to fit one minute video.

But if we can change audio speed for video, then a script of around 1200 characters can still fit the YouTube short format. This feature is adopted in CopyCopter, Fliki, and Veed (io); don't lose them for that.
