Colourful premiere countdown concept (for clarification, read description)

this video showcases a part of my premiere countdown concept.
a premiere countdown is a countdown that sometimes appear (may come in different themes) in the start of a video just before going public.
this video showcases the repetitivity in my custom premiere countdown.
e.g. for «7 minutes» (7:59 to 7:00) it showcases the repetitivity of these timestamps (it only shows the first 10 seconds).
when the screen displays «9 minutes», then that repetitivity will only be present in the timestamps 9:59 to 9:00. if it displays «8 minutes», then it will only be present in the timestamps 8:59 to 8:00, and so on
the exeption is when it says «0 minutes», it means 0:59 to 0:11. for the last 10 seconds, it shows a custom animation.
i was able to put music! yay!!!
