Three seconds decide

The opening three seconds of a vertical video decide whether a thumb moves on, so the music has no room for an intro. Generated material often arrives with four or eight bars of setup, and by the time the theme appears the viewer is elsewhere. Cut the best two bars to the front, or ask the tool to begin on the theme. The start does not have to be loud, but it has to be identifiable: a timbre, a rhythm, a single voice.

The caption zone

Captions usually sit in the lower half of a vertical frame, while platform buttons claim the right edge and the bottom. The midrange has to avoid the caption, which is less a visual problem than a problem of attention: the viewer is reading, so do not stack dense words or sharp synths at that moment. Keep the chorus sparse where captions appear, or yield a little high end when they do, and it will work better than turning the whole track down.

Loops and endings

Much vertical content replays, so the end has to lead back to the start. Ask for no intro and a seamless loop, then find the seam yourself, cut on the beat and clean the tail. Fifteen to thirty seconds is a common length; past a minute, consider sections or repetition will arrive before the content does. Do not fade out, because a fade in a loop is simply a drop in level.

Before posting

• A motif or a clear timbre appears within the first second
• The intro is gone, or was never there
• The midrange does not fight the captions
• The ending joins the opening seamlessly
• The hook survives a phone speaker without low end
• The licence covers a commercial account and paid promotion
• The generation record and prompt are kept
• Two music versions exist for the same footage

Habits that do not survive the crop

Cropping a landscape score into a vertical frame leaves hit points and captions misaligned. Keeping a long intro for polish is the most common way to lose viewers. Phone speakers reproduce almost no low end, so a hook placed there is no hook at all. Nor should one track serve every video, since recommendation systems group similar content and viewers tire of it. Posting before the licence is clear hurts most when a video does well.
