#### Rules and limits

- **Seedance scope.** Frame inputs are supported on **Seedance 2.0** and **Seedance 2.0 Fast** (`seedance-2-0`, `seedance-2-0-fast`). Sending `image`/`last_frame` to Seedance 1.5 Pro or any other ByteDance model returns a `400`.
- **Seedance scope.** Frame inputs are supported on **Seedance 2.0**, **Seedance 2.0 Fast**, and **Seedance 2.0 Mini** (`seedance-2-0`, `seedance-2-0-fast`, `seedance-2-0-mini`). Sending `image`/`last_frame` to Seedance 1.5 Pro or any other ByteDance model returns a `400`.
- **KLING scope.** Frame inputs are supported on **KLING v3.0** and **KLING v3.0 Turbo** (`kling-v3-0`, `kling-v3-0-turbo`). The gateway uploads base64 frames to AtlasCloud's media endpoint automatically, so both HTTPS URLs and base64 data URLs are accepted.
- **`last_frame` requires `image`.** Providing `last_frame` without `image` returns a `400`.
- **Not combinable with references.** First/last frame inputs (`image`, `last_frame`) cannot be combined with reference inputs (`reference_images`, `input_reference`, `reference_videos`, `reference_audios`).

### Reference-guided generation (Seedance 2.0)

Seedance 2.0 (`seedance-2-0`, `seedance-2-0-fast`) can generate a video that is guided by reference **images**, **videos**, and **audio** — sometimes called omni-reference. You attach references as top-level fields in the same `POST /v1/videos` payload; the gateway forwards each one to the provider tagged with the correct role, so you don't set roles yourself.
