Features
AI Highlights from Long Videos
AutoClip analyzes hour-long YouTube videos and surfaces the moments worth clipping, saving you from scrubbing through footage to find the good parts.
Vertical Reframe to 9:16
Full-width horizontal videos are automatically converted to YouTube Shorts' vertical format with AI speaker tracking keeping subjects centered.
Auto-Captions for Shorts
Word-level captions are generated and burned into every Short. Captions are essential for Shorts discoverability and watch time — AutoClip adds them automatically.
Direct YouTube Shorts Posting
AutoClip posts Shorts directly to YouTube on your behalf. Add a title, tags, and description, or let AutoClip generate them with AI.
How It Works
Paste the long YouTube video URL
Any long-form YouTube video works — interviews, lectures, podcasts, gaming VODs, commentary. You can clip any channel, not just your own.
AI extracts the best Short-worthy moments
AutoClip scores every segment of the video for viral potential and selects the top clips — typically 3–5 per hour of content.
Post Shorts directly to YouTube
Clips are uploaded as YouTube Shorts automatically. Your Shorts channel grows without any manual upload process.
Frequently Asked Questions
Can I turn someone else's long YouTube videos into Shorts?
Yes. AutoClip is a clipper tool — paste any public YouTube URL and generate Shorts. Many clippers run dedicated Shorts channels featuring highlights from their favorite creators, athletes, or podcasters.
What's the ideal length for YouTube Shorts?
Shorts perform best at 30–60 seconds. AutoClip targets this range by default. You can configure the target clip length if you prefer a different format.
How does AI decide which moments to turn into Shorts?
AutoClip transcribes the full video and uses AI to score each segment based on engagement signals — strong hooks, emotional peaks, quotable lines, audience reactions, and topic transitions that work well standalone.
Can I automatically turn every new upload on a YouTube channel into Shorts?
Yes. Channel monitoring watches any YouTube channel and automatically clips and posts new uploads as Shorts — all without any manual intervention.
Does AutoClip auto-generate titles and descriptions for Shorts?
Yes. AutoClip can generate SEO-optimized Shorts titles, descriptions, and hashtags using AI — you can use them as-is or edit before posting.
How many Shorts can I generate per month?
The Starter plan includes 10 videos/month, Pro includes 30, and Scale includes 100. Each video typically produces 3–5 Shorts.
