Submit an async video-generation task.

The request body shape depends on the model prefix:

• kling/... — Kling video request. Body fields are prompt + image + metadata.{mode, aspect_ratio, duration, image_list, video_list, sound, multi_shot, ...}. Endpoint variant (text-to-video / image-to-video / Omni-Video) is selected by which metadata fields you supply.
• byteplus/... — Seedance video request. Body fields are prompt + metadata.{content[], ratio, duration, generate_audio, watermark, seed, service_tier, return_last_frame, callback_url, resolution}. The variant (text-to-video / image-to-video / multimodal reference / video editing) is selected by which content[] items and role markers you supply.
• minimax/... — MiniMax-H3 video request. Body fields are prompt + duration + size + image/images + metadata.{ratio, first_frame_image, last_frame_image, video_urls, audio_urls, callback_url}. The variant (text-to-video / image-to-video / multimodal reference) is selected by which image / reference fields you supply; every video ships with native stereo audio.

Pick the schema variant from the request body dropdown below to see each shape's fields and try them in the playground.
