Supported formats include MP4 and MOV. You can also paste a direct video URL to import content quickly. Tip: Videos between 10 and 90 minutes typically yield the most Reels-worthy moments — aim for content-rich source material. 2 ### Let AI detect your best moments OpenClip's AI-powered viral moment detection scans your transcript and scores every segment by hook strength, narrative completeness, and engagement potential. Within minutes you'll have 5–15 clip candidates ranked by viral score. Tip: Prioritize clips with a strong opening hook — the first 1–2 seconds on Reels determine whether viewers swipe away. 3 ### Review and select your clips Browse the ranked clip list and preview each candidate. Pay attention to clips that open with a surprising statement, compelling question, or emotional moment — these perform best on Instagram's algorithm. Tip: Aim for Reels between 15 and 60 seconds. Clips under 30 seconds see the highest completion rates on Instagram. 4 ### Enable automatic speaker tracking OpenClip's AI-based face detection automatically identifies and crops to the active speaker in every frame, keeping your subject perfectly centered in the 9:16 vertical frame throughout the clip. Tip: Speaker tracking works best when the speaker is well-lit and facing the camera. Dark or heavily backlit footage may reduce tracking accuracy. 5 ### Add word-level AI captions Apply captions from OpenClip's 10 preset styles. For Instagram Reels, bold high-contrast styles like Beast, Pop, or Kendrick work exceptionally well. Captions are synced to every spoken word and can include emoji injection for extra personality. Tip: 85% of Instagram videos are watched without sound — captions are not optional, they're essential for Reels performance. 6 ### Export in 9:16 vertical format Select the vertical (9:16) export format optimized for Instagram Reels. OpenClip outputs your clip ready for direct upload — no additional resizing or editing needed. Tip: Export at 1080x1920 resolution for maximum quality. Instagram recommends a minimum of 500x888 but rewards higher resolution content. 7 ### Upload to Instagram and optimize your post Upload your exported clip directly to Instagram. Write a caption that complements the video, add 3–5 relevant hashtags, select an eye-catching cover frame, and post during your audience's peak activity hours. Tip: Use the first line of your Instagram caption as an additional hook — it shows before the 'more' cutoff and drives engagement. ## What You'll Achieve Polished, algorithm-friendly Instagram Reels with perfect 9:16 framing, word-level captions, and AI-selected viral moments — ready to upload in minutes. ## Features ### AI Viral Moment Detection AI scores every segment by hook strength and viral potential so you always clip the best moments. ### Auto Speaker Tracking AI face detection keeps your speaker perfectly centered in every vertical frame. ### Word-Level Captions 10 preset caption styles with per-word sync, emoji injection, and safe-zone positioning. ### 9:16 Vertical Export Export clips in Instagram-native vertical format at full 1080x1920 resolution. ### Batch Processing Process multiple long-form videos at once and generate up to 15 Reels candidates per video. ### Engagement Scoring Each clip is scored for hook strength and narrative completeness before you even preview it. ## Frequently Asked Questions ### What is the ideal length for an Instagram Reel?
