A starting point.

Before you publish.
Check subject consistency and camera movement from start to finish. Review the audio separately and confirm that the output fits your intended placement.

Inputs and settings
Select text, image or reference mode. Image mode requires image_url, optionally takes end_image_url and follows the input aspect ratio automatically. Reference mode uses image_urls.
Choose 4–30 seconds and 480p, 720p or 1080p. Choose an explicit aspect ratio for text/reference mode and select generate_audio. Automatic duration is unavailable.
Reference mode currently supports image guidance; editing, extension and video/audio references are unavailable. Encoding is fixed to standard bitrate and automatic codec. 1080p has a higher token rate; review the quote before submission.

From quote to result.

Follow the generation workflow, then poll the job for its status and result. The API and studio use the same balance.
