🎬 影片合併
把多段影片接成一個檔案。全程不上傳。
只適用於規格相同的片段。 這個工具是把各段直接複製進同一個檔案，不重新編碼，所以只要幾秒、畫質也完全不損失 —— 但前提是每一段的編碼格式、解析度、幀率與音訊設定都相同。同一台相機連續拍的片段，或用同樣設定匯出的檔案，一定符合。若你的檔案規格不同，工具會指出是哪一項對不上；請先把它們轉成相同設定再合併。
常見問題
Are my videos uploaded to a server?
No. The clips are joined locally in your browser. They never leave your device.
Why does it say my clips cannot be joined?
This tool joins clips by copying them into one container, without re-encoding — which keeps the original quality and takes seconds instead of minutes. Copying only works when every clip has the same codec, resolution, frame rate and audio settings. When they differ, the message names the property that does not match.
Which clips will always work?
Clips recorded back-to-back on the same camera or phone, and files exported from the same editor with the same settings. Those already share every parameter.
My clips differ. What can I do?
Run them through Video Convert first with the same output settings for each, then merge the results.
Does merging reduce quality?
No. Nothing is re-encoded — the original video and audio data are copied through untouched.
Can I reorder the clips before merging?
Yes. Drag the thumbnails to set the order, then merge.
