API usage

Generate video with client.videos(): POST /v1/videos/generations (long timeout).

Examples

Example response

Text only (no image)

RodiumAi SDK

videos() maps to POST /v1/videos/generations: allow up to 600s timeout.

Use cases

  • Bring a product photo, a poster or an illustration to life.
  • Animate AI-generated stills into short clips.
  • Keep a character or a scene consistent: start from the same first frame.
  • Turn a storyboard frame into a motion test.
  • Create looping hero banners from a brand visual.

Notes

  • Endpoint: POST https://api.rodiumai.io/v1/videos/generations, JSON body. model and prompt are required, image is the first frame.
  • image (also read from image_url, input_image) accepts a base64 data URL, raw base64 or {"b64_json": "...", "mime_type": "image/png"}. Models served by Google also accept a gs:// URI. Prefer inline base64: it works everywhere.
  • The output keeps the aspect ratio of the input image, so you usually do not need aspect_ratio or size.
  • A few models also take last_frame (end frame, frame interpolation). Check the model card.
  • Generation takes one to several minutes. Use a client timeout of at least 10 minutes and do not retry on timeout: a retry starts and bills a second video.
  • Billing is per second of video, or per generation for some models. See the pricing table above.
