Reverse Video — 常見問題

Is my video uploaded?+

No. It's reversed entirely in your browser.

Does the audio reverse too?+

Yes — both video and audio play backwards, so it sounds right, not just looks right.

Why the 30-second limit?+

Reversing needs every frame held in memory at once before re-encoding — there's no way to stream it. 30 seconds keeps memory use reasonable in a browser tab; trim a longer clip first with Trim Video.

Which browsers work?+

Chrome, Edge and Safari 17+ — reversal 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。
