Sometimes, you’d like to share a video with others, but the accompanying audio track is distracting or perhaps introduces privacy concerns. Luckily, there’s a quick way to silence a video using Photos on iPhone and iPad. Here’s how.
有時,您想與他人共享視頻,但是隨附的音軌卻分散了您的注意力,甚至可能引起隱私問題。 幸運的是,有一種快速的方法可以使用iPhone和iPad上的“照片”使視頻靜音。 這是如何做。
First, open the “Photos” app on your iPhone or iPad. In Photos, locate the video you’d like to silence and tap its thumbnail.
首先,在iPhone或iPad上打開“照片”應用。 在“照片”中,找到您要靜音的視頻,然后點擊其縮略圖。

With the video open, tap “Edit” in the upper-right corner of the screen.
打開視頻后,點擊屏幕右上角的“編輯”。

With audio enabled, a yellow speaker icon will appear in the upper-left corner of the screen. Tap it to disable the audio.
啟用音頻后,屏幕左上角會出現一個黃色的揚聲器圖標。 點按可禁用音頻。
Unlike other speaker icons in iOS and iPadOS, this is not simply a mute button. Tapping the yellow speaker removes the audio track from the video file itself, so that the video will be silent when you share it.
與iOS和iPadOS中的其他揚聲器圖標不同,這不僅僅是一個靜音按鈕。 輕按黃色揚聲器可從視頻文件本身中刪除音軌,以便在共享視頻時將其靜音。

With the audio for the video disabled, the speaker icon will change to a grayed-out speaker icon with a diagonal strike mark through it.
在禁用視頻音頻的情況下,揚聲器圖標將變為帶有灰色對角線標記的揚聲器圖標。
Tap “Done” to save your changes to the video.
點擊“完成”將更改保存到視頻。

Once the audio is disabled on a particular video, you will see a grayed-out speaker icon on the toolbar in Photos when you are examining the video. This means that the video has no audio component to it.
禁用特定視頻的音頻后,在查看視頻時,“照片”工具欄中的揚聲器圖標將顯示為灰色。 這意味著視頻沒有音頻成分。
If the icon looks like a crossed-out speaker in this spot, it could mean that you phone is merely silenced. Turn the sound back on and make sure the speaker icon is fully grayed out before sharing.
如果該圖標在該位置看上去像是喇叭狀的揚聲器,則可能意味著您的電話只是處于靜音狀態。 重新打開聲音,并確保揚聲器圖標在共享之前完全變灰。

Now you’re free to share the video however you wish, and no one will hear any sound when the video plays.
現在,您可以隨意共享視頻,并且在播放視頻時沒有人會聽到任何聲音。
如何恢復剛剛刪除的聲音 (How to Restore the Sound You Just Removed)
The Photos app saves the original videos and photos you edit, so you can undo your changes.
“照片”應用程序會保存您編輯的原始視頻和照片,因此您可以撤消更改。
After sharing, if you would like to undo the removal of the sound on the video, open “Photos” and inspect the video you’d like to fix. Tap “Edit” in the corner of the screen, then tap “Revert.” The audio for that particular video will be restored.
共享后,如果您要撤消視頻中聲音的去除,請打開“照片”,然后檢查您要修復的視頻。 點擊屏幕角落的“編輯”,然后點擊“還原”。 該特定視頻的音頻將被恢復。
