Quick Answer

Repurpose a 30-minute long-form video into 10 YouTube Shorts in under 60 minutes with Opus Clip, then amplify each with AI-written hooks and titles.

  • 1 long video = 10-15 Shorts opportunities
  • Hook in first 1.5 seconds or viewers swipe
  • Post 3 Shorts/day for 30 days for algorithm breakthrough

What You'll Need

  • A long-form YouTube video (podcast, webinar, tutorial) 10+ minutes
  • Opus Clip (free tier: 60 min/month) or Vizard.ai
  • Assisters for title + description writing
  • Canva for thumbnails (optional — Shorts auto-generate)
  • Google account with YouTube channel

Step 1: Upload Your Long Video to Opus Clip

Go to opus.pro → paste YouTube URL or upload MP4 → choose "Shorts" format (9:16) → let AI analyze (takes 3-5 min). Output: 10-15 auto-clipped Shorts ranked by virality score.

Step 2: Filter by Virality Score

Opus gives each clip a score out of 100. Keep clips scoring 85+. Discard <70 — they won't perform.

Step 3: Rewrite Titles for Hooks

Prompt Assisters: "Write 5 YouTube Shorts titles for a clip about [topic]. Use curiosity gap. Under 60 chars. Examples: 'I tried X for 30 days', 'Nobody talks about this X'."

Step 4: Add a 1.5-Second Text Hook

Inside Opus Clip editor → add text overlay at 0:00-0:01.5s: "Wait, this changed my mind…" or "I can't believe this worked." Bold white text, centered top.

Step 5: Write SEO Descriptions

Prompt: "Write a YouTube Shorts description for [topic]. Include 3 keywords, 5 hashtags, and link to full video." Always link to the source long-form in description.

Step 6: Batch Schedule via YouTube Studio

Upload all 10 clips to YouTube Studio → schedule 3/day at 10am, 3pm, 8pm local time. Turn on "Made for Kids: No" and add to a Shorts playlist.

Step 7: Monitor 48-Hour Performance

Check Analytics → Shorts tab → focus on "Audience Retention". If swipe-away rate in first 3 seconds is >40%, the hook failed. Rewrite and re-upload.

Common Mistakes to Avoid

  • Uploading full clips without re-hooking — they flop
  • Watermarking with TikTok logo (YouTube deprioritizes cross-posted content)
  • Ignoring the 1.5-second hook rule
  • Writing titles over 60 characters (truncates)
  • Posting <3 Shorts/day during growth phase
