Trim Video — 常見問題
Is my video uploaded?+
No. The clip is re-recorded from a canvas in your browser — nothing is sent anywhere.
Why does it take as long as the clip?+
This trims by playing the selected part and re-recording it in real time, so a 30-second clip takes about 30 seconds. It's the simplest approach that works in every browser.
Is the video re-encoded?+
Yes — the output is a fresh recording, so there's a small quality change. For short clips it's hard to notice.
What format do I get?+
MP4 where your browser supports recording it (Chrome, Safari), otherwise WebM.
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。
