Quick answer
Generate in vertical 9:16 from the start, hook the viewer inside the first two seconds, and keep clips short and caption-heavy since much of TikTok plays muted. The workflow: pick an idea, write a prompt (or use a one-click effect on a photo), generate in 9:16, add a voiceover or trending sound, and caption it. AI tools compress this to minutes per video, which matters because posting volume drives TikTok growth.
Format is half the battle: 9:16 generation composes the scene for a phone screen instead of cropping a landscape shot, and an immediate visual hook stops the scroll before the algorithm judges the video.
AI’s real advantage on TikTok is iteration speed — testing five hooks on the same concept costs minutes, not days, and the platform tells you quickly which one works.
