Data schema

Input

Field	Type	Description
seed	—	Random seed. A random seed is selected when omitted.
lorasrequired	array	List of LoRA adapters to apply to the transformer.
promptrequired	string	Text prompt for video generation
duration	integer	The duration of the video in seconds.
image_url	—	Optional URL of the image to use as the first frame. When provided, the output canvas follows this image. If only end_image_url is provided, the canvas follows that last frame instead. If both images are omitted, the request is handled as text-to-video (16:9 by default).
sync_mode	boolean	Return the generated video as base64 instead of a CDN URL.
resolution	stringenum: 480P, 768P, 2K, 4K	The resolution of the generated video. 480P and 768P are native generation modes; 2K and 4K upscale a 768P base result.
end_image_url	—	Optional URL of the image to use as the last frame. It may be provided alone for end-only keyframe generation; in that case the output canvas follows this image.
target_audio_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 requested video duration, keeping the beginning. The original audio replaces the output soundtrack, padded with silence if shorter than the video, without changin…
enable_safety_checker	boolean	If set to true, the safety checker will be enabled.
prompt_expansion_mode	—	How much effort to spend rewriting the prompt before generation. 'disabled' skips prompt expansion. 'fast' returns in about a second. 'balanced' picks per request. 'quality' spends up to ~30s on a richer prompt.

Output

Field	Type	Description
video	—	The generated video
expanded_prompt	—	The prompt after expansion, as sent to the model. Null when prompt expansion was disabled, left the prompt unchanged, or was performed internally by MiniMax's hosted API.
