Input

Field	Kind	Default	Description
`video` required	URL or file	—	URL of the input video containing the object to remove.
`prompt` required	text	—	Text description of the desired background after object removal.
`seed`	number (whole)	—	Random seed for reproducibility.
`strength`	number 0 to 1	1	Denoising strength. 1.0 means full denoising.
`mask_video`	text	—	URL of a mask video for the removal target. For best results this should be a VOID-style quadmask video with 4 grayscale values: 0=object to remove, 63=overlap, 127=affected region, 255=background to keep. A simple binary mask (0=remove, 255=keep) also works. If omitted, the app will generate a temporary mask video from `mask_prompt` using the SAM-3 video endpoint and convert it to a quadmask automatically.
`num_frames`	number (whole) 1 to 197	85	Temporal window size for inference. This value is snapped to the nearest CogVideoX-safe value that works with temporal compression and patching. Valid outputs are 69, 77, 85, ..., 197.
`mask_prompt`	text	—	Text description of what should be masked in the input video, such as the object or person to remove. Used to generate a temporary mask video with SAM-3 when `quad_mask_video_url` is not provided.
`guidance_scale`	number 0 to 20	1	Classifier-free guidance scale.
`negative_prompt`	text	—	Negative prompt to guide generation away from undesired outputs.
`num_inference_steps`	number (whole) 1 to 50	30	Number of denoising steps. Higher values improve quality but increase latency.
`enable_pass2_refinement`	true or false	false	Run VOID Pass 2 warped-noise refinement after Pass 1. This is slower but can improve temporal consistency on longer clips.
