Vertical AI Video Generator (9:16)

Short-form feeds are portrait-first, and so is veo3gen.co. Generate native 9:16 video with synchronized sound for TikTok, Reels, and Shorts using Google's Veo 3.1 — no awkward cropping required.

Built for the Vertical Feed

Cropping a horizontal video into portrait throws away half your frame and usually buries the subject. A true vertical AI video generator composes the shot for 9:16 from the start, so faces, products, and action sit where a phone screen wants them. Choose the 9:16 ratio before you render and the model frames accordingly.

Every clip arrives with native synchronized audio, which matters more than ever on platforms where sound-on viewing drives the algorithm. Your hook can have a beat, a voice, and an effect the moment it hits the feed.

Make a 9:16 Clip in Three Steps

  1. 1Set aspect ratio to 9:16. Pick portrait before generating so the model frames vertically from the first frame.
  2. 2Prompt for a strong hook. Lead with the subject and a clear action in the first second — short-form viewers decide fast.
  3. 3Render and post. Download a 4, 6, or 8 second clip with sound and drop it straight into TikTok, Reels, or Shorts.

Where Vertical Wins

TikTok

Native portrait clips with sound match the platform's full-screen, sound-on experience.

Instagram Reels

Generate hook-first openers and product moments that fill the frame edge to edge.

YouTube Shorts

Produce a steady stream of vertical clips to feed a Shorts channel without filming.

Vertical ads

Test portrait ad creative for Stories and in-feed placements before a paid push.

Framing Tips for Portrait

  • Keep the key subject centered vertically so captions and UI overlays do not cover it.
  • Front-load the action; the first second decides whether a viewer keeps watching.
  • Favor tighter shots — portrait rewards close subjects over wide establishing views.
  • Lean on the native audio to set energy from frame one.
