如何 Merge Videos

1
Add your clips
Drop in two or more videos — they're read in your browser.
2
Set the order
Use the arrows to arrange the clips; they play back to back.
3
Merge and download
Click Merge; the clips are played and re-recorded into one file in real time.

Do the clips need to match?+

No. Each clip is scaled to fit one common frame size (letterboxed if aspect ratios differ) as it's recorded.

Is anything uploaded?+

No — every clip is played and re-recorded in your browser.

Why does it take so long?+

It plays each clip in turn and records the result, so the wait is roughly the total length of all the clips.

What format do I get?+

MP4 where your browser supports recording it, 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。
