Seadanse

Seadanse is an independent web app that puts ByteDance Seedance 2.5 in your browser. Write a prompt or upload reference images, pick length and resolution, and get a multi-shot cinematic clip with a native soundtrack in the same pass — no Chinese phone number, no extra audio step. Seedance 2.5 renders 5–30 second clips at 480p, 720p or 1080p, keeps faces/products/style locked from your references, and generates music, foley, and ambience with the picture. Sign up is free with starter credits and no card required; every render shows its exact credit cost before you hit Generate. Renders are yours to use in ads, monetized posts, and client work under Seadanse terms.
