Request body

30 properties · 3 required · 2 $defs
propertytypedescriptionconstraints
video_url*stringThe URL of the video to reference.
prompt*stringThe prompt to generate the video from.
loras*LoRAInput[]The LoRAs to use for the generation.
video_strengthnumberVideo conditioning strength. Lower values represent more freedom given to the model to change the video content.0 ≤ n ≤ 1 · default: 1
audio_strengthnumberAudio conditioning strength. Lower values represent more freedom given to the model to change the audio content.0 ≤ n ≤ 1 · default: 1
generate_audiobooleanWhether to generate audio for the video.default: true
enable_prompt_expansionbooleanWhether to enable prompt expansion.default: true
seedintegerThe seed for the random number generator.nullable
image_urlstringAn optional URL of an image to use as the first frame of the video.nullable
use_multiscalebooleanWhether 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.default: true
enable_safety_checkerbooleanWhether to enable the safety checker.default: true
accelerationenumThe acceleration level to use.none | regular | high | full · default: "none"
preprocessorenumThe preprocessor to use for the generation.depth | canny | pose | none · default: "none"
num_framesintegerThe number of frames to generate.9 ≤ n ≤ 481 · default: 121
distill_lora_second_pass_scalenumberThe scale of the distill LoRA to use for the second and subsequent passes.0 ≤ n ≤ 1 · default: 0.5
fpsnumberThe frames per second of the generated video.1 ≤ n ≤ 60 · default: 24
schedulerenumThe scheduler to use.ltx2 | linear_quadratic | beta · default: "ltx2"
negative_promptstringThe negative prompt to generate the video from.default: "news broadcast, 3d animation, c…
match_video_lengthbooleanWhen enabled, the number of frames will be calculated based on the video duration and FPS. When disabled, use the specified num_frames.default: true
video_output_typeenumThe output type of the generated video.X264 (.mp4) | VP9 (.webm) | PRORES4444 (.mov) | GIF (.gif) · default: "X264 (.mp4)"
video_write_modeenumThe write mode of the generated video.fast | balanced | small · default: "balanced"
video_sizeImageSize | enumThe size of the generated video.default: "auto"
camera_loraenumThe 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.dolly_in | dolly_out | dolly_left | dolly_right | jib_up | jib_down · +2 more · default: "none"
camera_lora_scalenumberThe 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.0 ≤ n ≤ 1 · default: 1
end_image_urlstringThe URL of the image to use as the end of the video.nullable
video_qualityenumThe quality of the generated video.low | medium | high | maximum · default: "high"
audio_urlstringAn 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.nullable
sync_modebooleanIf `True`, the media will be returned as a data URI and the output data won't be available in the request history.default: false
ic_lora_typeenumThe IC LoRA type to use for the generation.match_preprocessor | union | detailer | none · default: "union"
match_input_fpsbooleanWhen true, match the output FPS to the input video's FPS instead of using the default target FPS.default: true

LoRA weight configuration.

scalenumberScale factor for LoRA application (0.0 to 4.0).0 ≤ n ≤ 4 · default: 1
path*stringURL, HuggingFace repo ID (owner/repo) to lora weights.
weight_namestringName of the LoRA weight. Only used if `path` is a HuggingFace repository, and is only required when the repository contains multiple LoRA weights.nullable
