About Seedance-2.0-fast
Seedance-2.0-fast is a Bytedance model that turns a text prompt into a video. It can add sound to match. The sound includes effects, ambient sounds and speech that lines up with the lips of people on screen. You write the prompt, then choose how the video looks and how long it runs.
The prompt is the only required input. Resolution has two choices: 480p generates faster than 720p. Aspect Ratio has seven choices. Auto lets the model decide. The others include 16:9 for landscape, 9:16 for portrait, 1:1 for square and 21:9 for ultrawide. Duration offers auto, which lets the model decide from your prompt, or a length in seconds. Bitrate Mode has standard and high. High asks for a larger file of higher quality.
Seedance 2.0 Mini offers the same resolutions but has no Bitrate Mode. The cost is the same whether Generate Audio is on or off. The price is 2419 credits.
