Reverse Video — 常见问题

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。
