Input Parameters

Name	Type	Description	Default	Constraints
`video`*	string(uri)	Input video file.	`—`	—
`crf`	integer	CRF value for output video quality (0-51). Lower values = better quality.	`19`	min: 0, max: 51
`custom_height`	integer	Custom height if force_size is not 'Disabled'.	`512`	min: 64, max: 2048
`custom_width`	integer	Custom width if force_size is not 'Disabled'.	`512`	min: 64, max: 2048
`denoise_strength`	number	Denoise strength (0.0 to 1.0). Higher = more deviation from input content.	`0.85`	min: 0, max: 1
`flow_shift`	integer	Flow shift for temporal consistency. Adjust to tweak video smoothness.	`9`	min: 1, max: 20
`force_rate`	integer	Force a new frame rate on the input video. 0 means no change.	`0`	min: 0, max: 240
`force_size`	string	Force resize method. 'Disabled' means original size. Otherwise applies custom_width/height.	`"Disabled"`	—
`frame_load_cap`	integer	Max frames to load from input video.	`101`	min: 1
`frame_rate`	integer	Frame rate of the output video.	`24`	min: 1, max: 120
`guidance_scale`	number	Embedded guidance scale. Higher values follow the prompt more strictly.	`6`	min: 1, max: 20
`height`	integer	Output video height (divisible by 16 for best performance).	`768`	min: 64, max: 2048
`keep_proportion`	boolean	Keep aspect ratio when resizing. If true, will adjust dimensions proportionally.	`true`	—
`prompt`	string	Text prompt describing the desired output video style. Be descriptive.	`"high quality nature video of a excited brown bear walking through the grass, masterpiece, best quality"`	—
`seed`	integer	Set a seed for reproducibility. Random by default.	`—`	—
`select_every_nth`	integer	Use every nth frame (1 = every frame, 2 = every second frame, etc.).	`1`	min: 1
`skip_first_frames`	integer	Number of initial frames to skip from the input video.	`0`	min: 0
`steps`	integer	Number of sampling (denoising) steps.	`30`	min: 1, max: 150
`width`	integer	Output video width (divisible by 16 for best performance).	`768`	min: 64, max: 2048
