The quality isn’t that high right now, but I think it’ll become better later since the original video is 720 p.
Anyway, this tutorial is dedicated to @simandy because she wanted to know how to do this. I hope this video will help a bit. If you want to see other tutorials just tell me, and I’ll see if I have the energy for it.
