How to make vertical short-form videos with AI

Vertical short-form video works best when the project is planned for 9:16 from the first scene. Here is how to turn a track, script, or brief into a Reels, TikTok, or YouTube Shorts-ready cut without relying on a late crop.

How to make vertical short-form videos with AI

1. Plan the vertical frame first

Choose a 9:16 aspect ratio before writing prompts so faces, products, captions, and camera moves are composed for the phone screen. Treat each beat as a short scene instead of shrinking a wide video after generation.

  • Set 9:16 before generation.
  • Break the idea into short, timed beats.
  • Write prompts around vertical framing and closeups.

2. Build captions into the edit

Captions are part of the creative system for social video. Use transcription and beat-aware timing to place readable lines on the timeline, then keep generated motion clear enough that text does not fight the shot.

  • Transcribe the track, voiceover, or script.
  • Use caption styles that fit quick viewing.
  • Review every cut on a vertical timeline.

3. Keep a series consistent

Short-form campaigns often need multiple posts with the same performer, product, world, or visual language. Continuity anchors and references keep generated clips from resetting the look between posts.

  • Reuse cast, product, and style references.
  • Route each shot by quality and cost.
  • Export vertical cuts for Reels, TikTok, and Shorts.
