I will share my free tool with you which allows you to make Lyrics Videos
for ie. posting on Youtube.
All you need is an mp3 of your Audio, a background image, a foreground image, and the lyrics you want to show transcribed when the mp3 is playing.
Just view this video to see how: https://www.youtube.com/watch?v=m4qHXvnVqrQ
And you can use OBS to record the playing result.
This service is completely free, but I wouldn't mind accepting simbis or if you pay it forward it's all good.
