Green Screen Remover — 常見問題

Is my video uploaded?+

No. The screen is keyed out and the new background composited entirely in your browser.

Does it need a real green screen?+

It works best with an evenly lit, solid, uncrinkled green or blue backdrop and no matching color in the subject's clothes or skin tone — the same conditions any chroma key tool needs.

Can I use my own background image instead of a color?+

Yes — switch to Image and upload one; it's scaled to fill the frame behind the keyed subject.

Which browsers work?+

Chrome, Edge and Safari 17+ — keying the video needs WebCodecs.

你們會把我的檔案上傳到伺服器嗎？+

不會——這裡的每個工具都完全在你的裝置上處理檔案，不會向伺服器上傳任何內容。唯一的例外是 AI 工具，它們會把擷取的文字（而非檔案本身）傳送給 Claude 來完成工作。

有檔案大小限制嗎？+

我們沒有人為設下限制，但由於處理過程在你的瀏覽器中進行，非常大的檔案（超過 500MB 或 1000 頁）會受你裝置記憶體的限制，而非我們的限制。
