prompt string

Text description for video generation, maximum 2000 characters

Supports camera movement control using [instruction] syntax. You can add camera instructions in the prompt using the [instruction] format for precise camera control.

Supported 15 camera instructions:
Pan: [pan left], [pan right]
Tilt: [tilt left], [tilt right]
Push/Pull: [push in], [pull back]
Rise/Lower: [rise], [lower]
Up/Down tilt: [tilt up], [tilt down]
Zoom: [zoom in], [zoom out]
Other: [shake], [follow], [static]

Usage rules:
Combined movements: Multiple instructions within the same [] will take effect simultaneously, e.g. [tilt left, rise], recommend no more than 3 combined instructions
Sequential movements: Instructions appearing before and after in the prompt will take effect in sequence, e.g. ”…[push in], then…[pull back]“
Natural language: Camera movements can also be described in natural language, but using standard instructions provides more accurate responses

Polling

Since result generation takes time, you need to poll the task status after creating the task.

The initial response only returns information such as the task ID and initial status. The final result must be obtained by polling the task status endpoint using the task ID.

See the examples on the right for polling requests and responses.
