Remove the sound from a video

When this comes in handy

• Background chatter or wind noise you don't want to post.
• A clip you'll put music on later in another app.
• Silent loops for websites and presentations, where autoplaying videos must be muted anyway.

Why it's instant

Video and audio are stored as separate tracks inside the file. Removing the audio means writing the video track into a new file without the audio track next to it, with no re-encoding, so even long videos take seconds and the picture quality doesn't change at all.
