Videos must be in 9:16 aspect ratio and can range from 1 second to 10 minutes, though 15–60 seconds consistently performs best for organic reach. Files should be MP4 or MOV. TikTok's algorithm heavily weights early retention, so the first 2 seconds are critical. Tip: TikTok's For You Page (FYP) algorithm looks at completion rate above all other signals. A 20-second video watched to completion is more valuable than a 60-second video watched halfway. 2 ### Extract clip-worthy moments with OpenClip AI Upload your long-form video to OpenClip. The AI scans the transcript and scores each segment for hook strength, narrative completeness, and viral potential. For TikTok, prioritize clips with an immediate, bold hook — ideally a provocative statement, a surprising fact, or a direct question in the first 2 seconds. Tip: Look for clips where the speaker says something counterintuitive or challenges a common belief. These 'pattern interrupt' moments drive high rewatch rates on TikTok. 3 ### Trim clips to the TikTok sweet spot After AI detection, fine-tune your clip's start and end points. For TikTok, aim for 21–34 seconds for maximum FYP distribution, or 45–60 seconds for deeper storytelling content. Cut anything after the main point is made — TikTok viewers drop off fast after the payoff. Tip: End your clip on a complete thought or a cliffhanger that makes viewers want to follow your account for more. Avoid trailing silence or extended outros. 4 ### Apply vertical formatting with speaker tracking Select the 9:16 export format in OpenClip. Speaker tracking automatically re-crops your source footage — whether it's horizontal podcast footage or a multi-speaker panel — to keep the active speaker centered in the vertical frame throughout the clip. Tip: For clips with multiple speakers, OpenClip's multi-speaker detection switches focus to whoever is talking, keeping the frame dynamic and natural. 5 ### Add bold, word-level captions Enable AI captions and choose a high-energy caption preset. Beast, Dan, or Pop work especially well on TikTok. Word-level sync highlights each word as it's spoken, which drives higher on-screen engagement. TikTok's own data shows captioned videos get significantly more views than uncaptioned ones. Tip: Position captions in the middle of the screen rather than the very bottom. TikTok's native UI (like/comment/share buttons and username) overlaps the bottom portion of the frame. 6 ### Write a scroll-stopping caption and use hashtags strategically Your TikTok text caption (the description shown under your username) should tease the value of the video without giving it all away. Keep it under 150 characters. Use 3–5 hashtags: one niche-specific, one mid-range, and one broad (like #LearnOnTikTok or #FYP). Avoid hashtag stuffing — TikTok's algorithm doesn't reward it. Tip: Start your caption with a hook question or incomplete statement that makes viewers curious before they even hit play. Example: 'This changed how I think about.' or 'Nobody talks about this, but.' 7 ### Post at peak engagement times TikTok's FYP algorithm considers early engagement velocity heavily. Posting when your audience is active maximizes initial likes, comments, and shares — which triggers broader distribution. Generally, Tuesday through Friday between 9am–12pm and 7pm–9pm local time perform well, though your analytics will show your specific audience's peak times. Tip: After you've posted 20+ videos, check TikTok Analytics under 'Followers' to see exactly when your specific audience is most active online. 8 ### Analyze performance and iterate In TikTok Analytics, monitor average watch time, traffic sources (FYP vs. followers vs. search), and follower growth per video. If a clip underperforms, examine whether the first 2 seconds have a clear hook. If retention drops off mid-video, the pacing or payoff timing may need adjustment. Tip: Clips that perform well on TikTok often share a pattern — identify that pattern in your analytics and brief your next round of clip selection around it. ## What You'll Achieve A polished, vertically formatted TikTok video with AI-powered captions, a strong hook, and the right length and metadata to maximize For You Page distribution. ## Features ### Hook-First AI Detection Scores every moment for hook strength so your TikTok opens with maximum scroll-stopping impact. ### Vertical 9:16 Auto-Crop Instant vertical re-framing with speaker tracking — no manual cropping or repositioning needed. ### TikTok-Style Captions Bold word-level caption presets like Beast and Pop designed for TikTok's fast-paced viewing environment. ### Multi-Speaker Tracking Automatically switches focus between speakers in interviews and panels for natural, dynamic framing. ### Completion-Rate Optimization AI selects narratively complete segments that hold attention from first second to last. ### Batch Clip Generation Process an entire content library at once and generate dozens of TikTok-ready clips in parallel. ## Frequently Asked Questions ### What is the best video length for TikTok? For most content, 21–34 seconds drives the highest FYP distribution because completion rates are easier to achieve. For storytelling or educational content, 45–60 seconds can work well if the hook is strong. Avoid going over 90 seconds unless your content consistently holds viewers to the end. ### Does OpenClip export in the right format for TikTok? Yes. OpenClip exports in 9:16 vertical MP4 format, which is exactly what TikTok requires. The exported file is ready to upload directly through TikTok's app or web uploader. ### Why are captions so important on TikTok? Many TikTok viewers scroll with sound off, especially in public spaces. Captions keep these viewers engaged and significantly improve watch time. TikTok's own research has shown that videos with text on screen retain more viewers than those without. ### Can I use a podcast or interview clip as a TikTok? Yes — this is one of the most effective TikTok strategies. OpenClip takes horizontal podcast or interview footage, extracts the best moments using AI, re-crops it to 9:16 with speaker tracking, and adds captions. The result is a native-feeling TikTok from content you've already created. ### How does TikTok's For You Page algorithm work? TikTok's FYP algorithm prioritizes completion rate (what percentage of the video people watch), rewatch rate, engagement rate (likes/comments/shares relative to views), and early engagement velocity (how fast a video picks up interactions right after posting). A strong hook that drives high completion is the single most important factor. ### How many TikToks should I post per week? TikTok rewards consistency. Most successful creators post 3–7 times per week. OpenClip's batch processing makes this volume achievable — upload one long-form video per week and generate enough clips to post daily without creating new content from scratch. ### Does OpenClip post directly to TikTok? Not currently. OpenClip exports your finished clips as video files that you upload manually through TikTok's app or web uploader. Direct publishing to social platforms is not a current feature. ### What types of content perform best on TikTok? Educational 'quick insight' clips, counterintuitive takes, personal stories with emotional arcs, and clips that teach something in under 30 seconds consistently perform well. OpenClip's AI is tuned to detect these types of moments in your long-form source content. ## Create Your First TikTok-Ready Clip Today Upload any long-form video and let OpenClip extract, format, and caption your best TikTok moments automatically.
