YouTube long-form,

Why Shorts cut from your own long-form perform best
YouTube’s Shorts algorithm rewards channels that repurpose their own long-form videos because the relationship signals are strongest. The Short links back to your long-form, watch-time pools across formats, and your audience sees both. Shorts cut from third-party content (with watermarks or source IDs) get demoted heavily.
- Clean, watermark-free 9:16 MP4 — no TikTok logo, no Instagram source ID, nothing for the algorithm to flag.
- Ranking optimized for hook + retention — exactly the two signals YouTube Shorts uses to decide your feed placement.
- 10 candidates per long-form — fills a month of daily Shorts uploads from a single long-form episode.
Common questions
Will YouTube penalize Shorts cut from my own long-form videos?+
No. YouTube actively encourages creators to repurpose long-form content into Shorts — Shorts cut from your own long-form videos can even link back to the source via the 'Related video' surface. The penalty risk is for clips that aren't yours, or that retain watermarks from other platforms.
What aspect ratio does YouTube Shorts require?+
9:16 (vertical) up to 60 seconds. AutoAIClips outputs 9:16 by default; you can also enable 1:1 and 16:9 in the same job for cross-posting to other platforms.
How long are the generated Shorts?+
Clip length follows the natural beat of the source — typically 25–55 seconds. The ranker prefers segments with a clean hook and storytelling closure, which usually lands well under the 60-second Shorts cap.
Can I link the Short back to my long-form video?+
YouTube auto-links Shorts to the related long-form video when both are on your channel. We export with your channel watermark and brand template; the relationship is established at upload time on YouTube's side.
