Seedance 2.0 on Replicate
Replicate's official guide + API for ByteDance Seedance 2.0 text/image/video-to-video
Replicate's engineering blog post 'How to make remarkable videos with Seedance 2.0' by Shridharathi, published 15 April 2026. It documents the model's multimodal input contract — up to 9 images, 3 video clips, 3 audio files and a text prompt in one generation, each addressable inside the prompt as [Image1], [Video1], [Audio1] — plus native synchronised stereo audio from the same engine, and time-coded multi-shot prompting in the form [0-4s]: ... [4-8s]: .... It ships copy-ready Python and JavaScript snippets against the model slug bytedance/seedance-2.0 and closes with a prompting-tips section. Use it as the canonical API-side reference when you need programmatic video generation rather than a web UI.
pip install replicateUse this over the Higgsfield UI whenever the video generation has to happen in code — it gives you the exact slug bytedance/seedance-2.0 and working Python/JS calls. Hard limits to design around: 15 seconds maximum per generation, 480p or 720p only, aspect ratios 16:9 / 4:3 / 1:1 / 3:4 / 9:16 / 21:9 / adaptive, and duration -1 to let the model choose. Structure long prompts as time-coded blocks and describe the audio explicitly, because audio is generated by the same pass — if you leave sound undescribed you get a soundtrack you did not ask for rather than silence.
Why it is here. It is the shortest path from 'we want AI video in the product' to a running API call, and the time-coded prompt grammar it documents is the piece most third-party tutorials get wrong.
