How people watch on TikTok
TikTok is watched full-screen on a phone, with sound often on, one swipe at a time. A clip has a moment to earn the next second, so a strong image and a spoken hook matter more than polish.
Set your video up for TikTok
- Choose vertical 9:16 so the video fills the screen
- Keep it short: a script of up to 20 words gives a video of 6 to 10 seconds
- Use a voiceover for a hook, or Energetic or Social music for mood
What to show first
- Open on the most striking image, not on a logo
- Say the hook in the first line of the voiceover
An example you can adapt
Example sentence: A pair of sneakers landing on a wet pavement in slow motion, neon reflections, vertical.
Example voiceover: "Stop scrolling. These might be the only sneakers you need this year." That script is 12 words, so the video falls in the "6–10 seconds" length and costs 2 credits in Full HD or 4 credits in 4K.
Mistakes to avoid on TikTok
- Opening with a logo or a slow build instead of the hook
- Making the clip longer than the idea needs, since short and clear tends to hold attention
Before you post on TikTok
- Check TikTok's current rules for AI-generated content, and label your video if asked to.
- Add captions or on-screen text in your editor if you want them
- Use sounds and tags the way the platform expects, and follow its community rules
