Loading API Reference...
CN8 is an AI gateway: a single proxy layer that gives you access to AI capabilities — chatbots with RAG, multi-agent orchestration, LLM completions, dubbing, TTS, media generation, and production-grade video/audio processing — all through one consistent API with unified auth, billing, and usage tracking.
Content-aware aspect ratio conversion with subject tracking, optional trim, and smooth camera pan.
The service trims the source if start/end are provided, then runs content-aware subject detection to determine optimal crop positions at the target aspect ratio. If smartcamerapan is enabled, crop positions are smoothed for natural motion. Output is encoded as a video at the new aspect ratio with original audio.
