Run it

Quote the input, start the generation with the quote, then poll the job. Set RAYWAKE_API_KEY first; see Authentication.

# 1. Price the exact input (quotes are valid for up to 10 minutes)

Input

Input fields for minimax/h3-max/text-to-video
Name	Type	Description
`prompt`required	string	Text prompt for video generation
`duration`	number (enum)	Video length in seconds. The output can run up to about 0.7 s longer than requested. Use at least 2 s with target_audio_url. Default: `5` One of: `1`, `2`, `3`, `4`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15`
`resolution`	string (enum)	The native generation resolution, or 1080P latent refinement from a native 768P source. Default: `768P` One of: `480P`, `768P`, `1080P`
`seed`	integer	Random seed. A random seed is selected when omitted.
`sync_mode`	boolean	Return the generated video as base64 instead of a CDN URL. Default: `false`
`prompt_expansion_mode`required	string (enum)	How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'balanced' returns in about a second. 'quality' spends up to ~30s on a richer prompt. Default: `balanced` One of: `disabled`, `fast`, `balanced`, `quality`
`target_audio_url`	string (URL)	Optional URL of an audio clip at least 2 seconds long (maximum 15 MB) to pin to the generated soundtrack. Longer clips are trimmed to the generated video's length, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changing playback speed. Exceptionally high sample rates may be resampled to 96 kHz. Accepts an HTTP(S) URL or a base64 data URI.
`aspect_ratio`	string (enum)	The aspect ratio of the generated video. Default: `16:9` One of: `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16`
