Try it on your own video
Paste any video URL and ClipSpeedAI generates TikTok-ready clips with animated captions, face-tracked 9:16 framing, and auto-scheduling. Go from raw footage to posted TikTok in minutes.
How it works, in one paragraph: paste a YouTube, Twitch or Vimeo link — or upload a file — and ClipSpeedAI transcribes it, finds the moments that stand on their own, and cuts them on sentence boundaries so nothing starts or ends mid-word. Each clip comes back reframed to 9:16 with the speaker's face tracked, word-by-word captions burned in, filler words and dead air stripped out, and a 0–100 viral score telling you which to post first.
What it costs: the demo is free for any video under 30 minutes (those clips carry a watermark). $1 unlocks three days of full Pro — clean exports, uploads up to 2 hours — then Pro is $29/month.
TikTok rewards content that hooks viewers in the first second, keeps them watching, and drives shares. ClipSpeedAI is built to find exactly those moments in any video. The AI analyzes speech patterns, emotional peaks, and audience retention signals to pull the clips most likely to perform on TikTok's algorithm.
Every clip ClipSpeedAI generates starts with a hook. The GPT-4o viral detection model prioritizes moments that open with strong statements, surprising revelations, or emotional tension. These are the patterns that stop TikTok scrollers and drive completion rates, which is the single most important ranking factor on TikTok.
All clips are automatically reframed to TikTok's native 9:16 aspect ratio. The AI speaker tracking system follows the active speaker across the frame, so talking-head content, interviews, and podcasts always look like they were filmed vertically. No black bars, no awkward cropping.
Captions are essential on TikTok, where a large share of users scroll with the sound off. ClipSpeedAI ships 11 animated caption styles that match the look of top-performing TikToks — word-by-word highlighting, bold keyword emphasis, and smooth animations that keep viewers reading through the whole clip. You can see every style side by side in the caption style preview, or read our breakdown of all 11 caption styles ranked by viral performance before you pick one.
The fastest way to lose a TikTok viewer is a clip that opens mid-sentence. ClipSpeedAI cuts along the transcript's sentence structure, so a clip begins where a thought begins and ends where it finishes — rather than being sliced at an arbitrary 30-second mark. Filler words and silences are stripped automatically, which usually tightens a clip by several seconds without touching the meaning.
If your source is a live YouTube, Twitch or Kick stream, ClipSpeedAI clips it in real time rather than waiting for a VOD. The best moment of tonight's stream can be on TikTok while people are still talking about it — the livestream clipping guide covers how to set that up.
Every clip ClipSpeedAI exports already matches these. Keep them handy if you are also editing by hand:
| Setting | Use this | Why |
|---|---|---|
| Aspect ratio | 9:16 vertical | Full-screen on the For You feed; anything else gets letterboxed |
| Resolution | 1080 × 1920 | TikTok re-encodes uploads, so 4K rarely survives the compression |
| Frame rate | 30fps (60fps for gaming) | 30 is standard; 60 only pays off on fast motion |
| Codec / container | H.264 MP4 | Universally accepted with no extra transcode generation |
| Bitrate | 8–12 Mbps | Below ~5 Mbps text and faces go blocky after re-encoding |
| Clip length | 21–60 seconds | Long enough for a complete thought, short enough to finish |
| Caption placement | Middle third | The UI overlays the bottom ~15% and the top-right corner |
| Max upload | 287MB mobile / 10GB web | A 60-second 1080p clip is only ~60–90MB |
If you want the reasoning behind these numbers — and the reframing trap that quietly softens every vertical crop taken from a 1080p source — read the full video resolution guide for Shorts, Reels and TikTok.
Connect your TikTok account and schedule clips directly from ClipSpeedAI. Set your posting times and let the tool handle distribution automatically.
GPT-4o prioritizes clips that open with strong hooks, matching TikTok's algorithm preference for high completion rate content.
Word-by-word animated captions in 11 styles, burned into the video so they survive re-upload and play with the sound off.
Ums, ahs and dead air are cut automatically. A rambling two-minute answer tightens into a clip that never gives the viewer a reason to swipe.
Each clip gets a viral score from 0-100 based on hook strength, emotional impact, and shareability. Post the highest-scoring clips first.
Process up to 10 videos at once. Generate a full month of TikTok content in a single session. Perfect for creators and agencies.
Repurpose your YouTube videos, podcast episodes, and live streams into TikTok content without re-editing. One long-form video can generate 10-15 TikTok clips, giving you weeks of content from a single recording session.
Agencies running TikTok accounts for multiple clients use ClipSpeedAI to process hundreds of videos per week. Batch processing and auto-scheduling eliminate the manual editing bottleneck that limits agency growth.
Run TikTok pages that curate and repurpose content from public sources. AI captions and reframing turn any horizontal video into native-looking TikTok content. Many operators run 5-10 pages simultaneously with ClipSpeedAI handling all the editing.
"I run 6 TikTok pages and ClipSpeedAI processes all of them. What used to take my team 30 hours a week now takes 2 hours. Our combined following went from 50K to 400K in 4 months."

The demo is free on any video under 30 minutes — no card, watermarked output. $1 unlocks three days of full Pro, then scale as your TikTok presence grows.
Paste the video URL (YouTube, Twitch, Vimeo and most public links) or upload a file. ClipSpeedAI transcribes it, finds the self-contained moments, cuts them on sentence boundaries so no clip starts or ends mid-word, reframes each one to 9:16 with face tracking, burns in word-by-word captions, and scores every clip 0–100 for viral potential. You download the ones you like or schedule them straight to TikTok.
ClipSpeedAI has a free demo for any video under 30 minutes — no card required. Free-demo clips carry a ClipSpeedAI watermark. To export clean, unwatermarked clips and upload videos up to 2 hours, the $1 three-day trial unlocks full Pro access, after which Pro is $29 per month.
TikTok accepts up to 10 minutes, but clips that finish a complete thought in 21 to 60 seconds tend to hold completion rate best, and completion rate is what the algorithm rewards. ClipSpeedAI cuts on sentence boundaries rather than fixed durations, so a clip runs exactly as long as the idea it contains rather than being chopped to hit a number. There is more on why length follows the idea in our breakdown of the 2026 TikTok algorithm.
1080×1920 at 9:16, 30fps, H.264 in an MP4 container, exported around 8–12 Mbps. TikTok re-encodes everything you upload, so a clean 1080p file usually looks the same as a 4K one after compression while uploading three to four times faster. ClipSpeedAI exports at these settings automatically.
Yes for live YouTube, Twitch and Kick streams — ClipSpeedAI clips them in real time while the stream is still going, so the moment is posted the same day rather than pulled from a VOD tomorrow. TikTok LIVE itself is not a supported live source; for TikTok you clip from recorded video or from your streams on the other platforms.
