YouTube Shorts generator from long videos
FrameOS helps creators convert long YouTube videos, podcasts, webinars, and interviews into vertical Shorts with captions and AI reframe.
Repurpose source videos into Shorts
Instead of manually hunting for moments, FrameOS creates a workflow for identifying candidate clips and preparing vertical short-form outputs.
Make Shorts reviewable
Creators can inspect candidate clips, captions, and reframing before the final render so the exported Short is ready to publish.
Turn your back catalog into Shorts
Every long upload you have already published is raw material. Paste a YouTube link or upload the file and FrameOS finds the moments that work as standalone Shorts, reframes them to 9:16, and captions them — so an existing library becomes a steady Shorts pipeline without re-filming anything.
Hook-first, because Shorts live or die on the open
YouTube Shorts rewards a strong opening. FrameOS ranks candidates by hook strength and shows the reasoning, so the clips you publish start with a reason to keep watching instead of a slow lead-in that loses viewers in the first two seconds.
Publish to Shorts in one click
After review, FrameOS can send a finished clip straight to YouTube Shorts, skipping the download-and-reupload round trip. The render is already vertical and caption-burned, so it is ready the moment you approve it.

FAQ
Can I turn a long video into multiple YouTube Shorts?
Yes. Long videos can contain multiple standalone moments that become separate Shorts when they are clipped, reframed, and captioned.
Why does YouTube Shorts need AI reframe?
Many source videos are landscape. AI reframe helps convert them to vertical without losing the main speaker or important action.
Can I make several Shorts from one long video?
Yes. A long video usually contains multiple standalone moments, each of which can become a separate Short once it is clipped, reframed, and captioned.
Does FrameOS publish directly to YouTube?
Yes — after you review a clip, one-click publishing sends it to YouTube Shorts without a manual upload step.
