Workflow

Choose a mode: text for scripted clips with aspect control, image for single-frame animation, reference for multi-subject consistency, or edit to transform existing footage.

Generate modes: write prompt → set duration/resolution (and aspect ratio if available) → submit → download from history.

Reference mode: upload images in order → reference them as character1, character2… in the prompt.

Video edit: upload source clip → describe changes → pick audio auto/origin → submit. Credits scale with source length.

All workflows run in the browser on FuseAITools with credit-based pricing—no local GPU required.
