Extract Viral Short Clips From Long Videos With Opus Clip

Use Opus Clip's AI to find the most engaging moments in your long-form video and export them as vertical clips with captions—ready for TikTok, Reels, and Shorts.

Prerequisites

• Opus Clip account (free tier: 60 min of video/month)
• A long-form video (YouTube, podcast recording, webinar, interview)
• The video should be at least 15 minutes; 30-60 minutes gives the best results

Step 1: Import your video

In Opus Clip, click New Project. Options to import:

• YouTube URL: Paste your video URL directly
• Upload: Upload MP4 from your computer
• Google Drive / Dropbox: Connect and import from cloud storage

For most workflows, pasting a YouTube URL (including unlisted videos) is the fastest path.

Step 2: Set clip preferences before processing

Before hitting generate, configure:

• Clip length: 30-90 seconds for TikTok/Reels, up to 3 minutes for YouTube Shorts (depends on content)
• Aspect ratio: 9:16 for TikTok/Reels/Shorts (vertical). 1:1 for Instagram feed posts.
• Speaker detection: Enable if there are multiple speakers. Opus Clip will center the frame on the active speaker.
• Topic filter: Optional. Enter keywords to bias toward clips about specific topics.

Step 3: Generate and wait

Click Generate Clips. Processing time: 5-15 minutes for a 60-minute video. Go do something else. Opus Clip is analyzing engagement signals across the entire video.

Step 4: Review the clip scores and rankings

Opus Clip returns 10-20 candidate clips, each with an AI "virality score" (0-100). The score predicts short-form engagement based on: strong hooks, complete ideas, emotional language, and punchy pacing.

What the score means:

• 80-100: Almost always post-worthy. Strong hook and clear idea.
• 60-80: Worth reviewing. May need minor trim.
• Below 60: Usually too slow, incomplete thought, or low-energy moment. Skip.

Watch the top 5-8 clips. Don't rely on score alone—you know your audience better than the algorithm.

Step 5: Trim and caption

For each clip you want to keep:

1. Trim: In the Opus Clip editor, drag the start/end handles to tighten the clip. Cut off slow intros. Make sure the hook lands in the first 2 seconds.

2. Captions: Captions are auto-generated. Review for accuracy—especially proper nouns. Change the caption style (font, color, animation) in the template selector. Bold, high-contrast captions with word-by-word animation perform best on TikTok and Reels.

3. B-roll cues: Opus Clip flags moments where B-roll would help. These are suggestions—you'd add B-roll in a separate editor if needed.

Step 6: Export

Export each clip as MP4. Naming convention: [VideoTitle]_clip_01.mp4, _clip_02.mp4, etc. This keeps your library organized.

Step 7: Schedule and post

Don't post all clips the same day. A good distribution schedule from one 60-minute video:

This stretches one video into 2 weeks of daily posting across three platforms.

What Opus Clip Does Well

• Finds moments you'd miss (the "random" insight at the 43-minute mark that becomes the best clip)
• Handles speaker-focused content better than anything else
• Captions are accurate and match timing well

What It Doesn't Do Well

• Highly visual content (cooking demos, physical tutorials) where the best moments need visual context, not just audio
• Heavily jargon-heavy content where the AI doesn't understand which moments matter in context
• Content where the pacing is slow throughout—the AI can't find a strong clip if there isn't one

Pro Tip: Give It Better Source Material

The clips are only as good as the source. Before uploading:

• Remove the first 2-3 minutes of setup/intro if they're slow
• Edit out long silent pauses and cross-talk in interviews
• If the video has a Q&A section, Opus Clip almost always finds strong clips there
