Short answer: copy the YouTube watch URL, paste it into ClipSpeedAI, and in a few minutes you get a set of vertical clips cut on sentence boundaries, reframed to 9:16 with the speaker's face tracked, captioned word-by-word, and each one scored 0-100 so you know the posting order. You never download the source file and you never open an editor.
It is free to try on any YouTube video under 30 minutes — you see the real clips the AI picked before you pay. Demo clips carry a small watermark. A $1 three-day trial removes it and raises the upload cap to two hours; Pro is $29/month after that. Live YouTube streams can be clipped while they are still running.

Clip a YouTube video free →ClipSpeedAI is built specifically for YouTube creators, clipping agencies, and faceless channel operators who need to repurpose long-form content into short-form clips at scale. Whether you are turning a 1-hour podcast into 15 viral Shorts or clipping highlights from a gaming stream, the entire workflow is a pasted URL and a few minutes of waiting, not an afternoon on a timeline.
Copy any YouTube video link and drop it into ClipSpeedAI. The platform supports standard videos, live streams, premieres, and Shorts. There is no need to download the video first. Batch processing lets you queue up to 10 YouTube URLs at once. If you would rather work from a file you already have, upload it directly instead — the rest of the pipeline is identical.
The AI reads the full transcript and audio to find the self-contained, emotionally charged moments — the ones that still make sense with no context in front of them. Each clip gets a viral score from 0 to 100, so you can prioritise what to post first instead of guessing. If you want to sanity-check a moment before you commit, the free viral score checker runs the same idea on a single clip.
Every clip is automatically reframed to 9:16 vertical format using AI face tracking, which follows the active speaker across the frame so they stay centred instead of drifting off the edge of the crop. Choose from 11 animated caption styles, burned in word-by-word. Seven layouts cover full-frame, split-screen and picture-in-picture, and you can also export 1:1 or keep the original 16:9. Export and post to YouTube Shorts, TikTok, Instagram Reels, or X — or schedule them from inside the app.
The single most common tell of an AI-made clip is an ending that stops mid-word. ClipSpeedAI cuts along sentence boundaries, so a clip finishes on a completed thought. Filler words and dead silence are stripped automatically, which is usually worth several seconds of runtime on a rambling podcast segment.
Before you post, it helps to know what YouTube will actually accept. These are the current numbers ClipSpeedAI exports against by default.
| Setting | YouTube Shorts | Why it matters |
|---|---|---|
| Max length | 3 minutes | Raised from 60 seconds in October 2024. Longer is allowed, but most clips still peak between 20 and 60 seconds. |
| Aspect ratio | 9:16 (vertical) or square | Anything wider gets letterboxed in the Shorts feed and loses screen area to black bars. |
| Resolution | 1080 x 1920 | Upscaling from a 720p source adds artefacts. Clip from the highest-quality source you have. |
| Frame rate | 30 or 60 fps | Match the source. Converting 60 to 30 on gameplay footage visibly stutters. |
| Captions | Burned in | Auto-captions can be toggled off by the viewer. Burned-in captions cannot, which is why they hold silent-feed viewers. |
| Source video cap | 30 min free / 2 hr paid | The free demo takes videos under 30 minutes. Paid plans take uploads up to two hours. |
If you are unsure how long a given clip should run, the Shorts length calculator works backwards from your retention curve rather than a rule of thumb.
The AI reads every second of your YouTube video to find the moments that stand on their own. Each clip gets a score so you know exactly which ones to post first.
Face detection keeps the active speaker centered in 9:16 vertical format. Works with interviews, podcasts, presentations, and multi-speaker content.
Word-by-word animated captions in styles like MrBeast, Hormozi, Gaming, and Minimal. Burned in, so they still read in a muted feed.
Every clip gets a viral score, hook rating, and engagement prediction. Stop guessing which clips to post. Let the AI tell you which ones will perform.
Queue up to 10 YouTube URLs at once. Process an entire week of content in one sitting. Perfect for agencies and multi-channel operators.
Schedule clips directly to YouTube Shorts, TikTok, Instagram Reels, and X. Set your posting calendar and let ClipSpeedAI handle distribution.
Paste a live YouTube, Twitch or Kick URL and clips arrive while the stream is still running — no waiting for the VOD to finish processing.
Lock your fonts and colours across every clip with a Brand Kit, or drive the whole pipeline from a developer API and an MCP connector for Claude.
Manual editing a single YouTube video into Shorts takes 2-4 hours. You have to watch the full video, find interesting moments, cut them, add captions, reframe to vertical, and export. Multiply that by the 3-5 videos most creators publish per week and you are looking at 10-20 hours of editing every week.
ClipSpeedAI does the same work in a few minutes per video. The AI watches your entire video, identifies the best moments, applies professional captions, reframes to 9:16 with speaker tracking, and gives you export-ready clips. That 20-hour weekly editing workload drops to about 15 minutes.
| One 45-minute YouTube video | Editing it yourself | ClipSpeedAI |
|---|---|---|
| Finding the moments | Watch all 45 minutes, scrub back, take notes | Automatic, every moment scored 0-100 |
| Cutting | Manual in/out points per clip | Cuts land on sentence boundaries |
| Vertical reframe | Keyframe the crop by hand, shot by shot | Face-tracked 9:16, 1:1 or 16:9 |
| Captions | Transcribe, time, style, fix errors | Word-by-word, burned in, 11 styles |
| Filler and silence | Hunt for every "um" on the timeline | Removed automatically |
| Realistic time cost | 2-4 hours | Paste the URL and walk away |
"I used to spend 3 hours editing each video into Shorts. Now I paste the URL and get 10 clips in a few minutes. My Shorts channel went from 500 to 45,000 subscribers in 3 months."

Try it free →The YouTube algorithm rewards consistency more than it rewards any single upload — the ranking signals behind what makes a Short go viral are broken down here — and consistency is exactly what breaks when editing takes hours. One long-form video is usually enough raw material for a week of Shorts, so the practical strategy is to clip once and drip the output rather than sitting down to edit every day.
Shorts are monetized inside the YouTube Partner Program: ad revenue from the Shorts feed is pooled each month, music licensing is paid out of that pool, and creators keep 45% of what is allocated to them. Shorts views do not count toward the 4,000 watch-hour threshold — Shorts channels qualify on a separate path of 10 million Shorts views in 90 days. Run your own numbers in the YouTube monetization calculator before you pick which path to chase.
Many creators use ClipSpeedAI to run faceless YouTube channels, repurposing podcast interviews, public domain footage and licensed content into Shorts without appearing on camera. If that is the model you want, start with the faceless YouTube channel guide, which covers niche selection and the sourcing rules that keep a channel out of trouble.
Most clipping tools require a finished file. ClipSpeedAI can attach to a live YouTube, Twitch or Kick stream and produce clips in real time, which matters because the demand for a stream moment peaks in the hours around it, not the day after. You paste the live URL, clips appear as the stream runs, and you post the best one before the moment has cooled.

Copy the watch URL and paste it into ClipSpeedAI. The AI transcribes the video, finds the self-contained moments, cuts each on a sentence boundary, reframes to 9:16 with face tracking, burns in word-by-word captions, and scores every clip 0-100. You download the ones you want and upload them to Shorts. No source download, no editing software.
Yes — the free demo runs on any YouTube video under 30 minutes, so you see the actual clips the AI picked before paying anything. Demo clips carry a small watermark. The $1 three-day trial removes the watermark and raises the upload cap to two hours; Pro is $29/month after that.
Up to 3 minutes. YouTube lifted the cap from 60 seconds in October 2024 and it still stands. In practice most clips perform best between 20 and 60 seconds, because a Short that ends before attention runs out gets replayed instead of skipped.
Yes. Paste the live URL and clips arrive while the stream is running, rather than after the VOD finishes processing. The same real-time path works for Twitch and Kick.
Minutes, not hours, scaling with the length of the source. A 20-minute talk finishes well ahead of a two-hour podcast. The honest comparison is manual editing, which runs two to four hours for the same handful of clips.
Yes. The 9:16 export is the same format TikTok, Reels and Shorts all use, so one run covers every vertical platform. See the TikTok clipping page for the platform-specific differences in length and caption placement.
Paste a URL and see the clips before you decide. Free on videos under 30 minutes, then $1 for three days.
