Social Trailer and Hook Cutdown

Social Trailer and Hook Cutdown

What it does

Extracts hook moments from long-form video and produces platform-ready short clips (9:16, trailer teasers, opening hooks).

When to use

• Long video → TikTok/Reels/Shorts cutdown
• Creating trailer or teaser clips
• Optimizing first 3 seconds for retention

Inputs

• Long-form source video
• Target platform (9:16, duration cap)
• Optional transcript for hook detection

Outputs

• Hook segment identification (timestamp + rationale)
• Cutdown clip list with in/out points
• Optional 9:16 crop/reframe plan

Steps

1. Transcribe or analyze source for high-energy/key moments.
2. Score segments for hook potential (first 3s impact).
3. Select cutdown windows respecting platform duration limits.
4. Plan 9:16 crop/reframe if needed.
5. Export clip list for LosslessCut/ffmpeg.

Quality checklist

• Hook lands within first 3 seconds
  
• Clip duration within platform limit
  
• 9:16 framing preserves subject
  
• No mid-sentence cuts at start/end
