You say
Reframe demo.mp4 using my-brand.json. The hook should be 'Build apps in minutes.' and the subtitle 'api-docs-generator'.
Your agent does
Processing demo.mp4... Applying brand styles from my-brand.json. Rendering frame with hook: 'Build apps in minutes.' Exporting vertical-demo.mp4 [1080x1920, H.264, 30fps]. Done. Output saved to social/vertical-demo.mp4.

About this skill
The problem
Horizontal screen recordings lose visibility on vertical social feeds. Traditional cropping cuts off two-thirds of the content, while letterboxing leaves wasted black bars that fail to grab attention during a scroll.
What it does
- Scales 16:9 video into a branded 9:16 frame without cropping the original content.
- Automatically generates high-impact text hooks and CTAs using brand-specific colors and typography.
- Uses a JSON-driven branding system to swap styles across different clients instantly.
- Calculates safe areas to ensure UI elements from TikTok and Instagram do not obscure text or video.
- Provides a batch processing mode to reframe entire folders of clips in one command.
Frameworks & tools
Python 3, H.264 MP4, and JSON configuration files.
Why this beats prompting it yourself
Manual video editing for every social clip is slow and prone to brand inconsistency. This tool handles the geometry, transparency masking, and typography layout programmatically, ensuring every export meets platform-specific safe zones without human error.
Use cases
- Creating LinkedIn or TikTok demo clips from desktop product recordings.
- Generating branded social video assets for multiple agency clients at scale.
- Iterating on hook copy using the instant preview mode before committing to a full render.
- Repurposing horizontal YouTube content into YouTube Shorts and Instagram Reels.
Known limitations
Fixed geometry designed for standard social safe zones. Sources must be 16:9 to avoid stretching. No native support for animated text hooks.
