Video: "Claude Code + Seedance 2.5 = Insane Websites" by Julian Goldie on YouTube.
What Seedance 2.5 is
Seedance is ByteDance's video generation model — the company behind TikTok and CapCut. Version 2.5 improves on earlier releases with better motion consistency across frames, longer clip output, and more reliable handling of text prompts that describe camera movement or scene transitions. You describe a visual in plain English and it produces a short video clip you can embed directly on a web page.
It is less widely covered in the UK than Sora or Google's Veo, but the output quality on short atmospheric clips — the kind that sit behind a homepage hero heading — is strong. For web use, the key practical advantage is that it generates MP4 files ready for embedding without needing post-processing in a video editor.
How Claude Code and Seedance 2.5 work together
Claude Code handles the structure. You describe the site you want — layout, sections, colour scheme, copy — and Claude builds the HTML, CSS, and JavaScript. This is well-established; Claude Code has been producing complete static sites from briefs for some time.
Seedance provides the visual layer. Rather than stock footage or placeholder images, Julian Goldie prompts Seedance 2.5 for specific clips — a slow-moving abstract background, a product-adjacent scene, a cinematic establishing shot — and embeds those into the site Claude built. The result is a finished site where both the code and the visuals were generated from written descriptions.
The workflow in the video is roughly: write the site brief, generate the video assets in Seedance, drop the Seedance output into the Claude-built layout, and adjust. No Figma, no stock library subscription, no video editor involved at any point.
What the finished result actually looks like
Motion backgrounds make a plain HTML page look substantially more polished immediately — that is the core of what this combination delivers, and Julian Goldie demonstrates it clearly. The standard of motion on Seedance 2.5 clips is good enough that a non-designer viewing the output would not identify it as AI-generated. The code side is well-structured, clean HTML that renders consistently across browsers.
This is not a production web application. There is no CMS, no backend, no e-commerce layer. But for a landing page or a service overview site, the output is directly usable as a starting point — which puts it meaningfully ahead of a blank page or a generic template.
What you still need to bring yourself
The "insane websites" framing in the title is about visual impact, not about producing something your business can run without further work. The generated site needs a domain, hosting, and someone to update the content when it changes. For it to be found in search, you need metadata, a sitemap, structured data, and page speed considerations that Claude Code will not handle automatically.
Getting the Seedance visuals to match your brand — the right colour palette, the right subject matter, the right mood — takes several iterations. The first output from a prompt is rarely the one you use, and refining it takes time. And the copy Claude writes for a generic brief will read generically unless you give it your actual positioning, tone, and the specific things that make your business different from a competitor.
Where this connects to NordSys
A generated site is a starting point. Getting from a Claude Code and Seedance output to something you can actually put your business behind, on your domain, with your copy, structured for search, and updated as your offer changes, is the work our Web Design service covers. We build sites from £29/month that are designed to be used, not just to look good in a demo.
