Cut a long YouTube video into 90-second X clips with native captions, hook-first framing, and a thread that drives replies. Full workflow plus Kompozy automation.
A YouTube video earns watch-time over 8 to 20 minutes. An X post earns replies in the first 140 seconds — that is the hard length cap for free accounts. Repurposing across this gap is less about cropping and more about deciding which 90-second slice of a 12-minute video can survive on its own, then writing a thread around it that earns the reply, the quote, and the bookmark.
The second axis that matters is text. YouTube descriptions are SEO real estate. X captions are conversational hooks limited to 280 characters on the free tier. A thread of 4 to 6 posts built around one clip outperforms a single clip post by a wide margin, because each reply post is another impression in the algorithm.
Creators making this move are usually podcasters, educators, or commentary channels chasing X's reply-loop economics. A single YouTube produces 3 to 5 clip-able moments; each becomes a self-contained X thread with the clip pinned at the top. The reach math is asymmetric — the clip is the bait, the thread is the conversion, and the YouTube link sits in the last post as the call to action.
YouTube exports 16:9 MP4 up to 256 GB. Auto-captions ship within minutes and the SRT side-car from YouTube Studio is usually accurate enough to reuse downstream as burned-in subtitles. Description and chapter markers tell you where the audience already paused — those are your clip candidates.
X (Twitter) free accounts cap video at 2 minutes 20 seconds and text at 280 characters; Premium raises both (up to 4 hours of video and 25,000 character posts). Most clips should target 60 to 90 seconds so the loop replays once before the viewer scrolls. Captions must be burned in — X auto-captions exist but are off by default for many viewers and the silent-autoplay default means no captions equals no message.
| Issue | Fix |
|---|---|
| Clip uploaded at over 2:20 silently truncates on free accounts | Trim to 2 minutes 18 seconds maximum before upload; X cuts the tail without warning. |
| YouTube end-screen branded outro carried into the clip | Strip the YouTube branded outro entirely; X viewers will not recognize your channel template and the last 5 seconds tank completion rate. |
| Vertical 9:16 clip letterboxes inside the X timeline preview | Keep 16:9 or recompose to 1:1 with the speaker centered; X favors landscape over vertical in feed. |
| Burned-in YouTube watermark visible in the corner | Crop a 40-pixel border or use the original master file before YouTube re-encoded it. |
| Auto-captions misread niche vocabulary and look amateur on a long-form expert clip | Use the YouTube SRT (more accurate than X auto-captions on technical terms) and edit obvious misreads before burning. |
| "Watch the full video" CTA on-screen cuts X completion | Move the CTA to the final post of the thread. On-screen link-in-bio text hurts loop completion which hurts ranking. |
Following the workflow above by hand: trimming, reframing, captioning, writing copy, publishing.
Paste the source URL or upload the file. Kompozy handles transcript, scoring, reframe, captions, copy, and publish.
60 to 90 seconds is the sweet spot. Free accounts hard-cap at 2:20. Anything under 30 seconds tends to under-perform because viewers want a complete thought before they reply.
Landscape 16:9 or square 1:1. X timelines favor landscape; 9:16 letterboxes inside the timeline preview and loses face area.
No. Free accounts can post 2:20 video and 280-character threads. Premium helps if your clips routinely run over 2:20 or you want longer single-post copy, but it is not required for this workflow.
Sometimes, and the result is unreliable on technical vocabulary. Burn captions in from the YouTube SRT instead — they are accurate and survive any setting the viewer has chosen.
A 10-15 minute video typically yields 3 to 5 standalone clip-able moments. Each becomes a separate thread, posted across 3 to 5 days.
Yes — paste the YouTube URL, Kompozy extracts the transcript, scores moments, renders 60-90s clips with burned captions, drafts the thread copy, and queues posts on a stagger. Typical run: 4 minutes.
