A tier list is a ranking that sorts things into groups, from S at the top down through A, B, C and D, instead of numbering them one by one. A tier list video shows that ranking being filled in, item by item, so the viewer finds out where each one lands as you talk about it.
This maker draws the board for you: a title, rows in the familiar red, orange, yellow and green, and text chips that drop into their tier one after another and land with a small bounce. Rows grow to fit what's in them. It works with words only: there's no image upload, so each item is a short label of up to 24 characters.
Plan the timing around what you'll say. Time per item sets the gap between one chip landing and the next, from 0.3 to 2 seconds, so a slow, talky ranking wants a longer gap than a quick-fire one. Set Drop order to Best last to keep the top tier for the end.
