Hooks that stand without the intro
A Short has three seconds to earn the next ten. The selection favours passages that open on a claim or a question and close on their answer, so the clip makes sense to someone who has never seen the channel.
FOR YOUTUBE CREATORS
Turn long YouTube videos into Shorts.
Long-form is where the channel lives; Shorts are where new viewers find it. Cutting them by hand is an evening per video. shortshort reads the transcript, picks the passages that stand alone, reframes on you and captions every word, so one upload gives you the week of Shorts.
60 free credits, no cardUp to 3 hours per videoMP4 · 1080 × 1920
The same clip for Shorts, Reels and TikTok
Every export is a 1080 x 1920 MP4, H.264, 30 fps: the format all three platforms accept as is. One render, three posts.
Your framing, kept
B-roll, wide shots and inserts are detected and kept full-frame. When you are on camera, the crop follows you, with emphasis zooms on the words that carry the point.
Free to try on a real video
The 60 welcome credits cover a 22-minute video almost three times over, with up to 3 Shorts per video and a watermark on the export. A plan removes the watermark.

Questions people ask
Can I paste a YouTube link?
No. shortshort works from a file: export the video from your editor or download your own upload from YouTube Studio, then drop the MP4.
Will the Shorts have a watermark?
Exports on the free tier carry a small shortshort watermark. Every paid plan removes it.
How do I pick which moments become Shorts?
The AI proposes them from the transcript; in the studio you can change a passage in and out, adjust the framing keyframes and the captions, then render again. You can also cut a passage by hand.
Which caption styles are available?
Four: Spotlight, the default, lights up the word being said; Impact highlights one word per line in bold; Karaoke colours words as they are spoken; Minimal keeps plain readable text.
