What you can build with this

Personalized video at scale Feed user data as JSON props, render a unique video per user. Think Spotify Wrapped, GitHub Unwrapped, onboarding walkthroughs — one template, thousands of outputs.

Automated social media clips Pull live data (stats, leaderboards, product metrics) and render daily or weekly video posts without anyone touching a timeline editor.

Dynamic ads and marketing videos Swap in customer name, product image, pricing. Same template, infinite variations. Render server-side via API or Lambda.

Animated data visualizations Turn dashboards and KPI reports into shareable video clips with animated charts and transitions.

TikTok and Reels captions Transcribe audio, display word-by-word highlighted subtitles, export ready for upload.

Product showcase videos Auto-generate from your database — images, specs, pricing — straight to MP4.

Educational and explainer content Animated course materials, certificate videos, step-by-step walkthroughs — all driven by code.

Video generation as a service Expose rendering as an HTTP endpoint. Your app sends JSON, gets back a video file.
