Using Seedance Studio

A short guide to the studio's controls, the underlying Seedance 2.0 API on fal.ai, and how to read the estimated cost widget.

Add your fal API key

The studio never ships with a server key. Open Settings from the gear icon in the top bar and paste a key from fal.ai/dashboard/keys. The key lives in your browser's localStorage. On each generation it travels through a thin proxy route on our server that forwards it to fal.ai and nothing else.

Pick a mode

Seedance Studio supports two endpoints on the Seedance 2.0 family:

Text to video. Prompt only. Defaults to the standard tier at 0.014 USD/sec. Toggle Fast tier to drop to 0.0112 USD/sec at a small quality cost.
Image to video. Upload a JPEG, PNG, or WebP up to 10 MB. The model uses it as the opening keyframe and animates outward from it. Fast tier is not available in this mode.

Parameters

duration

4, 5, 6, 8, 10, 12, or 15 seconds. Pricing scales linearly; a 15s fast render costs about $0.17.

resolution

480p for faster iteration, 720p for final output. Cost is unchanged between the two.

aspect_ratio

auto, 21:9, 16:9, 4:3, 1:1, 3:4, or 9:16. Auto matches the reference image in image-to-video mode.

generate_audio

On by default. Produces ambient sound, effects, and lip-synced dialogue. Pricing does not change if disabled.

seed

Optional integer for reproducibility. Leave blank to get a fresh result each time.
