Clips finds the tempo and every part (verses, pre-chorus, chorus, bridge) and makes a vertical lyric video for each one, cut on the beat, with the words synced. Pick a layout and one of 54 effects, then export every part on every backdrop at once, named and ready for Ads Manager. Run them all for a week and put your budget behind the part that wins.
