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.
Dubbing
dubbing
Script-then-render video dubbing with the original soundtrack preserved.
Dub a video in two async stages. Stage 1 transcribes with word-level timing and translates the dialogue into editable, time-coded lines. Stage 2 voices the approved lines and mixes them onto the video, ducking the original only while a line plays.
POST core-dubbing → async job; result_data.data.segments is the dub script
POST transcript-audio-description-render → async job; result_data.data has video_url + audio_url
