Input

Fields marked * are required. Review the price before generating.

Text prompt for video generation

Video length in seconds. The output can run up to about 0.7 s longer than requested. Use at least 2 s with target_audio_url.

The native generation resolution, or 1080P latent refinement from a native 768P source.

Tips and requirements

How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'balanced' returns in about a second. 'quality' spends up to ~30s on a richer prompt.

Optional URL of the image to use as the first frame. When provided, the output canvas follows this image. If only end_image_url is provided, the canvas follows that last frame instead. If both images are omitted, the request is handled as text-to-video (16:9 by default).

Additional settings

Random seed. A random seed is selected when omitted.

Tips and requirements

Optional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Longer clips are trimmed to the generated video's length, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changing playback speed. Exceptionally high sample rates may be resampled to 96 kHz. Accepts an HTTP(S) URL or a base64 data URI.
