Canvas ports

These appear as port handles on the left side of the node.

ID	Label	Details
prompt	Prompt	TEXT (required) · multiline — Up to 2500 characters. Describe the restyle. Reference the source clip as @Video1, character elements as @Element1, @Element2…, and reference images as @Image1, @Image2…
video_url	Source Video	VIDEO (required) — mp4 or mov, 3–15s, at least 720px on both sides and at most 3840px, 24–60fps, max 200MB.
image_urls	Reference Images	IMAGE — Style / appearance references, addressed in the prompt as @Image1, @Image2… Elements plus images may total at most 4. Prefer the numbered Image 1/Image 2 sockets — this array port is the fan-in fallback.
element1	Element 1	ARRAY — Character 1. First wire = frontal image, the next up to 3 = reference angles.
element2	Element 2	ARRAY — Character 2. First wire = frontal image, the next up to 3 = reference angles.
image1	Image 1	IMAGE — Style / appearance reference.
image2	Image 2	IMAGE — Style / appearance reference.
elements	Elements (JSON)	ARRAY — FALLBACK for agents and imports: the raw FAL shape, [{ frontal_image_url: "…", reference_image_urls: ["…"] }]. Entries without a frontal_image_url are dropped. 🔴 A WIRED element1/element2 REPLACES this port entirely — the numbered sockets are what the prompt's @Element1/@Element2 count, so composing the two would silently renumber them. Elements plus reference images may total at most 4.
