YouTube to Shorts

Every long video on your channel is a stack of Shorts you haven't posted yet. ChunkyMonkey turns a YouTube link into up to 15 vertical, captioned clips — each scored for predicted virality and ranked best-first — without re-editing anything. Paste the URL, approve the top of the list, post.

How it works

From link to ranked Shorts

1

Paste the YouTube link

Any video on your channel — new upload or five-year-old back catalog. Or upload the file directly (MP4, MOV, MP3, up to 4 hours).

2

AI finds the Shorts

The model scans the full video for hooks, payoffs and self-contained moments, reframes them to 9:16, and captions every word.

3

Post the best first

Clips come back ranked by virality score, so you lead with the strongest moment. Auto-post on paid plans, or download and publish yourself on Free.

Why it works

Built for YouTubers with a back catalog

Your back catalog is an asset

You already did the hard part — recording hours of content. Repurposing works through the archive one video at a time, turning past uploads into a steady Shorts pipeline.

Shorts are a discovery funnel

Shorts reach viewers who would never find a 40-minute video. A strong Short with a clear hook sends new viewers to the long-form original and your subscribe button.

No re-editing, no timeline

The clip, the crop and the captions are done when they arrive. Your job shrinks to a judgement call on a ranked shortlist.

FAQ

YouTube to Shorts, answered.

How do I repurpose a long YouTube video into Shorts?
Paste the video's URL into ChunkyMonkey. The AI scans the full video, cuts the strongest moments into 9:16 captioned clips, scores each for predicted virality, and returns them ranked best-first. A 30-minute video costs 30 credits — half the free plan's monthly 60.
Can I make a Short from a video I already uploaded?
Yes — that is the core workflow. Paste the existing video's YouTube link; there is no need to re-upload the source file. This is how you work through a back catalog without touching an editor.
Does posting Shorts hurt my long-form views?
The short answer from YouTube itself: Shorts and long-form are recommended by separate systems, and Shorts don't drag down long-form performance. What Shorts can do is introduce your channel to viewers who then binge the long stuff — which is why a hook that points back to the full video matters.
How long should a YouTube Short be?
Shorts can now run up to 3 minutes, but shorter usually retains better — most winning Shorts land between 20 and 45 seconds, long enough for a hook and a payoff. ChunkyMonkey cuts to the moment's natural length, and the virality score reflects how well the pacing holds.
Is there a free YouTube to Shorts converter?
ChunkyMonkey's free plan covers 60 upload minutes a month — roughly two 30-minute videos — with scoring, captions and reframing included and a watermark on exports. Removing the watermark starts at Starter, $15/month.
