Coldplay Affair AI 如何製作簡單的雙照片網頁工具
Why the Coldplay affair filter works as a simple two-photo web tool
Coldplay Affair AI 將兩人的照片合成到 AI 生成的演唱會大屏幕畫面中，製成簡單的網頁工具。工具可使用每人一張清晰照片，或一張包含兩人的照片；影片採用連續 12 秒鏡頭，輸出為 9:16 直度、720p MP4，約需 3 分鐘渲染。照片會在 24 小時內刪除，工具與 Coldplay 無關。
The Coldplay affair filter took over TikTok almost overnight: two people caught on a concert big screen, one hides, one ducks, and the crowd goes wild. Most people tried to recreate it with CapCut templates, green screens and a lot of editing.
I wanted to see how simple the same idea could be as a web tool. The result is Coldplay Affair AI (https://coldplayaffair.com/). You upload one clear photo of each person, or one photo of both, and the AI places them on its own AI-made concert big screen, in their own clothes.
A few things I learned while building it:
- One continuous 12-second shot feels more convincing than stitched clips.
- A vertical 9:16 720p MP4 with crowd sound is all TikTok, Reels or a group chat needs.
- Rendering takes about 3 minutes, so failed renders should return the credit automatically.
- Photos should be deleted within 24 hours, and everything shown is AI-generated, with no real concert footage.
It is an independent tool and is not affiliated with Coldplay.
