You just recorded a 30-minute YouTube video and you know there are at least 5-6 great clips that could become TikToks or YouTube Shorts — but reviewing the whole thing to find and cut each clip takes a lot of time. AI cutdown tools solve exactly this problem.
How AI Shorts cutdown works
AI cutdown tools analyze your video and automatically identify:
- Segments with strong "hooks" (compelling questions, attention-grabbing claims, high-emotion moments)
- Self-contained segments — with a clear beginning and end that work without context
- Appropriate duration (typically 15-60 seconds for TikTok/Shorts)
Popular AI cutdown tools
Opus Clip
Currently the most widely used tool among creators. Upload your long video, Opus Clip analyzes it, selects the best segments, reframes to 9:16, and adds auto-captions. You receive 5-10 Shorts candidates to choose from. Free tier available but with monthly minute limits.
Vidyo.ai
Similar to Opus Clip — upload video, AI finds the most viral-potential segments, exports in platform formats (TikTok, Reels, Shorts). Includes auto-caption and branding features.
Munch
Munch focuses on finding high-engagement segments based on language and emotion analysis rather than just tempo. Better suited for podcast or talk-format videos.
CapCut (Highlights feature)
CapCut has an "Auto Highlights" feature in its desktop/web version — free and convenient if you already use CapCut for editing. Not as powerful as Opus Clip but no additional cost.
Practical workflow
- Prepare source video: Upload to Opus Clip or Vidyo.ai — or download from YouTube first if it is already published
- Run AI cutdown: Wait for processing (typically 5-15 minutes depending on length)
- Review candidates: AI suggests 5-10 clips — watch and select the ones that are actually strong
- Manual editing: Most clips need additional work — trim beginning/end, correct captions, add text overlays
- Export and publish: Export to platform specs (TikTok/Reels 9:16, Shorts 9:16)
What still needs manual editing after AI cutdown
- AI may cut the beginning or end too early or too late — trim to tighten
- Check AI-generated captions for accuracy (especially proper names, technical terms)
- Add a hook text overlay at the start if the clip opening is not immediately grabbing
- Verify the 9:16 reframe doesn't crop the speaker's face or important visual elements
