Explainer Video through MCP
Explainer Video uses explainer_video and creates continuous animated scenes with narration.
Call kp_get_catalog first, then pass these arguments to kp_create_creation:
{ "type": "explainer_video", "prompt": "Explain MCP with continuous animated scenes", "language": "en", "aspect_ratio": "16:9", "duration_seconds": 30}duration_seconds belongs only to Explainer Video and must follow the current catalog limits. Select voice_id, style_id, and output_quality from the same catalog when needed.
After creation, poll kp_get_job_status, then read the result with kp_get_creation. For a supported scene, use kp_edit_creation with update_scene_narration or regenerate_scene.
