Seedance 2.0 - AI Model API and Pricing

Where continuity is the whole job

Seedance 2.0 is aimed at shots where a character and a look must match across frames. Think of a mascot that turns its head without its face changing. A stylized short where the line work must not drift fits too. So does a sequence of clips that will be cut together and need the same person in each.

The model supports image, video and audio references, but on Ugesi it takes one image. Feed it a clear character sheet or a style frame instead of describing the look from scratch every time.

Writing prompts around a reference

Let the reference carry identity and let the prompt carry action. Try "The character from the reference image walks into a rainy alley. They stop under a neon sign and look up, same outfit, same hair." That prompt keeps the description short and points back at the file.

For style holds, try "Flat 2D animation in the style of the reference frame. A fox chases paper lanterns across a hill at night." Name what must not change. The model has no way to know which details you care about.

Resolution and settings

Output is 480p or 720p, with no native 4K. Every clip comes with generated audio. Use 480p while you check that the character holds, then render the keeper at 720p. Need a larger frame for delivery? Plan an upscale step after the render rather than expecting it here.

What it costs

The rate is 26 credits per second. Clips run 4, 6, 8 or 10 seconds. Every 5 seconds costs 130 credits, about $1.38 at the best pack. A 10-second clip costs 260 credits, about $2.77. It sits 21st from the cheapest of 31 models priced this way. Rates in that group run from 2 to 205 credits, so a long drafting session adds up fast.

Cheaper or different options

Wan 3.0 at 21 credits per second is the pick for longer shots where cost per second matters. It fits when strong camera movement is the point, though it is not the sharpest in its class. Gemini Omni 1.1 Flash costs 18 credits per second. It gives native audio, can start from your image and renders up to 4K. However, it caps runs at 10 seconds and adds a SynthID watermark. Sora 2 Pro shared the 26-credit rate. Its API shut down on September 24, 2026, and it no longer runs.
