Parameters

Name	Type	Default	Description
prompt required	string	—	Describe the video scene; use Shot 1: / Shot 2: for multi-shot or image 1 / video 1 for omni-reference. Best for cinematic narration or product demos.
first_frame_url	string	—	Image URL to anchor the starting frame; mutually exclusive with reference_images. Best for product shots and character-led scenes.
last_frame_url	string	—	Image URL to define the final frame; requires first_frame_url set. Use for scene transitions or story resolution.
reference_images	string[]	—	Up to 9 image URLs for style or character consistency; cite as image 1 in prompt. Fewer references yield stronger influence.
reference_videos	string[]	—	Up to 3 reference videos (2-15 seconds each) for motion/style transfer. Cite as 'video 1' in your prompt. Requests with reference videos are billed at the video-to-video token rate.
reference_audios	string[]	—	Up to 3 reference audio files (MP3). Cite as 'audio 1' in your prompt. Cannot be used with text+audio only — include an image or video input too.
duration	enum	5	Video length in seconds: 4, 5, 6, 8, 10, 12, or 15; -1 for auto. Use 5s for social posts, 10-15s for product demos.
resolution	enum	720p	Output resolution: 720p recommended for production; 480p for faster previews or low-bandwidth delivery.
aspect_ratio	enum	16:9	Output dimensions: 16:9 for widescreen, 9:16 for mobile Reels, 1:1 for feed posts, 21:9 for cinematic.
generate_audio	boolean	true	Enable native audio co-generation (dialogue, SFX, ambient, music); set true for final delivery, false for draft iterations.
seed	integer	-1	Integer for reproducible output; -1 generates a new random seed each run. Fix seed when iterating on prompt changes.
return_last_frame	boolean	false	Return the final frame as a separate image URL; useful for chaining clips or extracting scene-end stills.
bitrate_mode	enum	standard	Output video encoding bitrate. 'standard' gives smaller files and faster downloads; 'high' produces ~5-6x higher bitrate for better visual fidelity and fewer compression artifacts (larger files). Does not affect price.
auto_resize	boolean	true	Automatically resizes an input image that falls outside the provider's accepted range (300-6000px per side, aspect ratio 0.4-2.5, 30MB) so the request succeeds instead of being rejected. Aspect ratio is preserved: oversized images are downscaled, undersized ones upscaled, and out-of-band ratios padded rather than cropped. On by default - set it to false to have the provider reject out-of-range images instead. When a resize happens the response carries an X-Input-Normalized header naming the field and the before/after dimensions.
