What this site is
Seedance 2.5 Free is a free, single-screen job builder for a Seedance 2.5 video prompt. You write the prompt, attach reference images, video and audio, set the first and last frame, choose ratio, resolution, duration and sound, then copy the prompt or download the job as a text or JSON file.
The site is published at freevideoprompt.com and served as static files from Cloudflare Pages.
What it does
- Assembles a complete job on one screen and copies it, or downloads it as .txt and .json.
- Reads your uploads in your own browser and shows thumbnails, counts and length warnings.
- Draws a local preview frame from your first and last frame so you can check framing before a render.
- Works at phone width with touch-sized controls and no horizontal scrolling.
What it does not do
- It does not run the model. No AI video is rendered on this site — the preview frame is drawn locally from your own first and last frame.
- It has no accounts, no sign-in and no payment. Nothing you type or upload leaves your device.
- It keeps no history: closing the tab clears the prompt and the uploads.
- It is not a host, renderer or API. Whether a render runs somewhere else depends on that host.

Common questions
Is Seedance 2.5 open source?
No. There is no official open-source release of Seedance 2.5 that you download and run: the official model page offers an API and a playground, not a code or weights download, and public discussion of the release treats it as a closed model. Practically, you cannot host it yourself, so "free" here never means "free copy of the model" — you reach it through the official playground, an API provider, or a product built on top of it. This site is none of those three. It is static files that assemble a job sheet in your browser, render nothing, and stay the same whichever host you take the job to.
Is there an official Seedance app, and is this site official?
No, this site is not official — Seedance is a model family by ByteDance, and this page is an independent tool with no affiliation to ByteDance (stated in the section above). On the "official app" half of the question: this site cannot verify what apps exist and will not guess; what it can point to is the official entry, the model family's own page, which offers an API and a playground. Anything presented as an app or a free generator beyond that should be checked, not trusted — before you sign up or pay anywhere, ask four questions: who runs this site, is there a public price, does it state its relationship to the model maker, and can you reach a person at a published address. This site answers those four about itself on the About and Contact pages, and asks nothing of you that triggers them: no account, no card, nothing to install, nothing uploaded — just a URL that assembles a job sheet in your browser.
