Turn YouTube Videos into Shorts with Captions, Safe Zones, and Export Settings
YouTube Shorts demand a specific format: vertical 9:16 aspect ratio, under 60 seconds, with captions placed inside the safe zone so they are not covered by the channel avatar, like button, or description overlay. Shortify handles all of this automatically.
Type a topic — anything from a hot take on pop culture to a product explainer — and Shortify writes the script, generates an AI voiceover, overlays captions in the safe zone, and pairs it with trending background gameplay or b-roll. The result is a ready-to-upload Short that meets every platform requirement.
How It Works
- Enter your idea. A one-liner is enough — Shortify expands it into a scripted short-form narrative.
- Pick a style. Choose brainrot, storytime, explainer, or character dialogue to set the tone and pacing.
- Configure visuals. Select background gameplay, caption style, font, and branding. Safe zones are applied automatically so captions never overlap YouTube UI elements.
- Preview and render. Watch a real-time preview, then export a 9:16 MP4 optimized for YouTube Shorts — ready to upload.
Platform Constraints Shortify Handles
- Aspect ratio: 9:16 vertical (1080 × 1920 px recommended)
- Max length: 60 seconds
- Safe zones: Captions positioned to avoid the bottom bar, subscribe button, and title overlay
- Caption placement: Center-screen within safe margins, with customizable font size, color, and animation
- File format: MP4 with H.264 codec for universal compatibility
Whether you run a faceless channel, repurpose long-form content, or need scroll-stopping clips for your brand, Shortify gives you the fastest path from idea to published YouTube Short.
