# Theo · Video Generation

> The Theo Motion family handles every video request from a single branded surface. Intelligent style + duration routing inside the engine, native-audio support on cinematic engines, and an AI-disclosure watermark on every output.

## At a glance
- Engines (branded): Theo Motion (cinematic / commercial / documentary), Theo Motion Uncensored, Theo Animate, Theo Animate Pro, Theo Ovi (anime / animated).
- Intelligent style routing: a video classifier reads the prompt and selects style (cinematic / commercial / documentary / casual / animated) and target duration before dispatch.
- Native audio on the cinematic engines.
- Image-to-video supported on every engine via a separate endpoint.
- AI-disclosure watermark applied to every generated mp4 before upload.

## Style → engine mapping
- cinematic / commercial / documentary → Theo Motion (best quality, native audio).
- casual / auto → Theo Motion (speed-optimized variant).
- animated / anime → Theo Animate / Theo Ovi.
- Fallback chain per style runs inside the engine. The end-user sees one branded surface.

## AI-disclosure watermark
Every Theo Motion and Theo Stealth Motion output is piped through a watermarking pipeline before persistence. A tiny semi-transparent "theo" wordmark (~108px wide, ~16px padding) is overlaid in the bottom-right corner of the final frame. This is a provenance signal, not a branding toggle: it is applied regardless of operator branding preference. Expect ~2–15 seconds of additional re-encoding latency per video.

## API
- Primary endpoint: POST /api/v1/completions with mode "video" or with a video-intent prompt that the routing engine promotes.
- Body fields: prompt (required), style (optional), duration (optional, allowed values depend on engine), engine (optional pin), image_url (optional, enables image-to-video).
- Response: queue-based async. SSE stream emits tool events as the video classifier and the engine progress; final artifact event contains the persistent URL.
