What is a long-video-to-short-video AI tool?

A long-video-to-short-video AI tool takes a long recording — a podcast, webinar, interview, or livestream — and automatically cuts it into short vertical clips ready for TikTok, Reels, and YouTube Shorts. It transcribes the audio, scores which moments are most engaging, then reframes, captions, and trims each clip on its own. What used to take an editor hours per video happens in minutes from a single upload or link.

What these tools do

  • Auto-detect highlights and hooks from a full recording
  • Reframe horizontal footage to vertical 9:16 with face tracking
  • Animated captions burned in and styled per clip
  • AI-scored virality ranking for each suggested clip
  • Auto B-roll, emojis, and background music added
  • Bulk export or schedule to TikTok, Reels, Shorts

How it works

The tool transcribes your video and runs the transcript through a model that spots complete, self-contained moments with a strong hook. It ranks those segments, then for each one crops to vertical using face or motion tracking, burns in synced captions, and trims dead air. You review the ranked clips, tweak captions or framing, and export or publish.
