Flip-clock animation for Kdenlive, in a library clip, which you can expand (you'll need 6 tracks) and then change the text/color/font/everything, and also use together. More info in my youtube tutorial : https://youtu.be/5l2ot-M-GBI

Download then copy the file to your library folder (.local/share/kdenlive/library or C:\Users\name\AppData\Roaming\kdenlive\library), and it should just appear when you start kdenlive
