Parameters

Input parameters accepted by this model

Parameter	Type	Description	Default
`prompt` required	string	Text description of the video, motion, and sound to generate	-
`image_url`	url	First-frame image. Switches to image-to-video mode.	-
`end_image_url`	url	Last-frame image. Requires image_url.	-
`reference_images`	string	Up to 9 image URLs that guide subject and scene identity. Cannot be combined with image_url / end_image_url.	-
`reference_videos`	string	Up to 3 video URLs (2-15s each, max 50MB) that guide motion and scene identity. Cannot be combined with image_url / end_image_url.	-
`reference_audios`	string	Up to 3 audio URLs (2-15s each, max 15MB) that guide voice and sound. Cannot be combined with image_url / end_image_url.	-
`aspect_ratio`	enum	Output aspect ratio. Ignored in image-to-video mode — the start frame sets the aspect. `16:94:31:19:163:4`+1 more	`16:9`
`resolution`	enum	Output tier: 2k (5 credits/sec) or 768p (2 credits/sec). Ignored in image-to-video mode — a start frame forbids explicit dimensions, so those jobs render and bill as 2k. `2k768p`	`2k`
`duration`	integer	Video duration in seconds (5-15) min: 5 \| max: 15	`5`
`seed`	integer	Random seed for reproducibility	-

View Details

Joey and Chandler sit side by side on the couch with coffee cups. Joey turns to Chandler with a completely sincere, concerned expression. DIALOGUE: JOEY: “Could AI replace us?” Chandler slowly looks up from his coffee. Pauses. Looks Joey dead in the eye. CHANDLER: “Joey, AI cannot replace you. Nothing can replace you. Well, except Pixel Dojo.” Joey nods slowly. Visibly relieved. Processing. JOEY: “Because It's too good?” Chandler stares at him. Long beat. He looks down at his coffee, then back up. CHANDLER: “…That's right. It just is.” STYLE: Warm 90s sitcom aesthetic, steady handheld feel, natural performances, characters in casual clothing. Joey played completely straight — zero irony. Chandler delivers every line with exhausted deadpan sarcasm. Hold on Chandler’s face after the final line for a full beat before cut.”
