Video Generation

The Playground supports asynchronous video tasks with MiniMax and Doubao video models. After you select a model, Board automatically switches to the matching protocol, available options, and price estimate.

Create a video

  1. Open Playground and choose Video.
  2. Select an available MiniMax or Doubao video model and API key.
  3. Enter a prompt and optionally upload one reference image.
  4. Set the duration, ratio, resolution, and seed.
  5. Review the estimate and click Create.

Prompts can contain up to 7,000 characters. After submission, the task status is shown in the list and the completed video can be previewed or downloaded.

The available options depend on the selected model. Switching models refreshes the resolution options and price estimate.

Image input

The Playground accepts one image per task. Supported formats are JPEG, PNG, WebP, HEIC, and HEIF, with a maximum size of 30 MB. Adding an image changes the ratio to adaptive. Board sends the image through the selected video protocol and does not expose the original image as a public URL.

Price and balance

The estimate is based on the selected model, duration, resolution, and configured platform pricing. The amount shown before submission is an estimate; the wallet is charged using the price rules captured when the task is created. A task is not created when the balance is insufficient.

If a video task fails or is cancelled, the platform settles the refund according to the task state. Usage records can appear with a short delay while asynchronous settlement is synchronized.

Task states

StatusMeaning
QueuedThe request was accepted and is waiting upstream processing
RunningThe upstream service is generating the video
SucceededThe video is stored by Board and can be previewed or downloaded
FailedUpstream generation or result transfer failed; see the task details
CancelledThe task was cancelled and settled according to the billing state

Video generation is asynchronous. After the upstream reports completion, Board still transfers the result into private storage. A task can therefore remain Running briefly after upstream generation has finished.

MiniMax and Doubao

The two models use the same Playground workflow but different protocol and parameter limits. Board selects the correct protocol from the chosen model; users do not need to enter /minimax or /doubao paths manually.

If a model is missing from the selector, it may not advertise video support, may not be available to the current organization, or its upstream may be unavailable.
