## How to make a short video

1. **Choose 9:16**: Vertical fills the screen on TikTok, Reels and Shorts.
2. **Describe one moment**: One subject, one action and one camera move per clip.
3. **Download and post**: Add captions or a voice-over in your favorite editing app.

## What makes a short AI video work

Short-form video is watched with the thumb on the screen. The first second decides whether people stay, so put the most striking motion at the start and keep the subject large in the frame.

- Open on movement, not on a static scene
- Keep the subject centered for vertical framing
- Choose one clear action per clip
- Loopable motion, such as waves or rotation, rewards replays
- Use longer clips only when the action needs them

## From clips to a finished post

Each clip is 5 to 15 seconds. For a longer post, generate several related clips and join them in an editing app. Keeping the same style words and light in every prompt, or starting each clip from a matching image, makes the sequence feel consistent.
