The phrase "opus clips" has become shorthand for AI-generated auto-clips from long-form videos — livestreams, podcasts, interviews, lectures. But you don't need to use Opus Clip itself to make opus clips. Any AI tool that analyzes your long video and extracts the best moments as vertical shorts with auto-captions does the same job — and many do it better. In this complete guide you'll learn how to make opus clips from scratch using Viral Day, step by step, with tips that apply to any auto-clipping tool.
What are opus clips and why do they work?
The first step is picking the right source video. Opus-style clips work best with spoken content — podcasts, interviews, reaction streams, live broadcasts, recorded lectures. The clearer and better-edited the original audio, the more accurately the AI identifies high-engagement moments. On Viral Day, you can upload videos up to 40 hours long, or simply paste a YouTube link. The AI downloads the video, analyzes it end-to-end, and automatically generates a list of clips ranked by viral potential — all without you touching the timeline.
Step by step: creating your first opus clip
After the AI generates your opus clips, the next phase is what separates a complete platform from a simple auto-clipper: editing. In the original Opus Clip, you get the clips and you're done. In Viral Day, every clip flows directly into a professional editor where you can fine-tune captions (fonts, colors, word-by-word animation), apply your brand kit, reframe with face tracking, cut dead silence, censor profanity for any platform, and add logos or visual elements — all in one screen. When you're done, export in 1080p and schedule directly to YouTube Shorts, Instagram Reels, and TikTok.
- Pick spoken content: podcasts, livestreams, interviews, and lectures work best
- Upload directly or paste a YouTube link — the AI downloads and analyzes automatically
- Edit every opus clip with captions, brand kit, face tracking, and silence removal
- Publish the highest-scoring clips first, then use performance data to guide the rest
Advanced tips to maximize reach on your clips
Final tip for mastering opus clips: don't publish everything. The AI will generate 10 to 20 clips from a 1-hour video, each with a viral potential score. Publish the 3 or 4 highest-scoring clips first, see which one performs best, and publish the rest guided by what you learned. Creators who use this strategy extract months of social content from a single 2-hour livestream. That's how opus clips actually work — it's not about quantity, it's about consistency and smart curation.
