Input

Field	Kind	Default	Description
`prompt` required	text	—	The prompt to generate the video from.
`video_url` required	URL or file	—	The URL of the video to reference.
`audio_url`	URL or file	—	An optional URL of an audio to use as the audio for the video. If not provided, any audio present in the input video will be used.
`image_url`	URL or file	—	An optional URL of an image to use as the first frame of the video.
`end_image_url`	URL or file	—	The URL of the image to use as the end of the video.
`match_video_length`	true or false	true	When enabled, the number of frames will be calculated based on the video duration and FPS. When disabled, use the specified num_frames.
`num_frames`	number (whole) 9 to 481	121	The number of frames to generate.
`video_size`	JSON	auto	The size of the generated video.
`generate_audio`	true or false	true	Whether to generate audio for the video.
`use_multiscale`	true or false	true	Whether to use multi-scale generation. If True, the model will generate the video at a smaller scale first, then use the smaller video to guide the generation of a video at or above your requested size. This results in better coherence and details.
`match_input_fps`	true or false	true	When true, match the output FPS to the input video's FPS instead of using the default target FPS.
`fps`	number 1 to 60	24	The frames per second of the generated video.
`scheduler`	one of ltx2, linear_quadratic, beta	ltx2	The scheduler to use.
`acceleration`	one of none, regular, high, full	none	The acceleration level to use.
`camera_lora`	one of dolly_in, dolly_out, dolly_left, dolly_right, jib_up, jib_down, static, none	none	The camera LoRA to use. This allows you to control the camera movement of the generated video more accurately than just prompting the model to move the camera.
`camera_lora_scale`	number 0 to 1	1	The scale of the camera LoRA to use. This allows you to control the camera movement of the generated video more accurately than just prompting the model to move the camera.
`negative_prompt`	text	news broadcast, 3d animation, computer graphics, pc game, console game, video game, cartoon, childish, watermark, logo, text, on screen text, subtitles, titles, signature, slowmo, static	The negative prompt to generate the video from.
`seed`	number (whole)	—	The seed for the random number generator.
`enable_prompt_expansion`	true or false	true	Whether to enable prompt expansion.
`video_output_type`	one of X264 (.mp4), VP9 (.webm), PRORES4444 (.mov), GIF (.gif)	X264 (.mp4)	The output type of the generated video.
`video_quality`	one of low, medium, high, maximum	high	The quality of the generated video.
`video_write_mode`	one of fast, balanced, small	balanced	The write mode of the generated video.
`loras` required	JSON	—	The LoRAs to use for the generation.
`distill_lora_second_pass_scale`	number 0 to 1	0.5	The scale of the distill LoRA to use for the second and subsequent passes.
`video_strength`	number 0 to 1	1	Video conditioning strength. Lower values represent more freedom given to the model to change the video content.
`audio_strength`	number 0 to 1	1	Audio conditioning strength. Lower values represent more freedom given to the model to change the audio content.
`preprocessor`	one of depth, canny, pose, none	none	The preprocessor to use for the generation.
`ic_lora_type`	one of match_preprocessor, union, detailer, none	union	The IC LoRA type to use for the generation.
