Trim Video — 常见问题
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.
你们会把我的文件上传到服务器吗？+
不会——这里的每个工具都完全在你的设备上处理文件，不会向服务器上传任何内容。唯一的例外是 AI 工具，它们会把提取的文本（而非文件本身）发送给 Claude 来完成工作。
有文件大小限制吗？+
我们没有人为设置限制，但由于处理过程在你的浏览器中进行，非常大的文件（超过 500MB 或 1000 页）会受到你设备内存的限制，而非我们的限制。
