About Seedance 2.0
Seedance 2.0 is a video generation model from ByteDance. It supports text-to-video, image-to-video with first and last frame control, and multimodal reference-to-video.

FAQ about Seedance 2.0
What is the API ID of Seedance 2.0?
seedance-2.0 — put this into the model field of your request.
How do I request a video?
POST to /v1/videos/generations with model and prompt. The same key and the same base URL as for text models — only the path changes. The answer comes back when the clip is ready, with a link to the mp4 in data[0].url. The full request description, the parameters and curl, Python and Node.js examples are in the video generation documentation.
Which parameters does Seedance 2.0 accept?
prompt — the scene description, duration — 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 seconds, resolution — 720p, aspect_ratio — 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, generate_audio for sound, frame_images to animate an existing frame. Values outside this list are refused with a clear error, and anything you leave out is filled from the model's defaults.
What does one clip cost?
Video is not billed in tokens but in generations from a video bundle: 720p — 4×. A longer clip costs proportionally more than a short one. The remaining generations are shown in your account and in the key dashboard.
How long does it take?
A render takes from tens of seconds to a few minutes. The connection is held with a keep-alive, and if the model answers with an async job the proxy waits for it and hands back the finished clip — you do not need to poll anything yourself.
What if a render fails?
The claimed generations are refunded automatically — a failed render costs nothing. If it keeps failing, try another aspect ratio or a shorter clip: not every combination is supported by every provider.
Can I try it without writing code?
Yes: the Studio tab in your key dashboard has an Images / Video switch where duration, resolution and aspect ratio are picked with buttons. Video bundles are on sale in your account.
