Mute an MP4 file use cases
When to mute an MP4 before sharing
Mute an MP4 when it has background chatter, copyrighted music, keyboard noise, or confidential meeting audio under an otherwise useful clip.
Browser processing vs upload-based tools
A server editor has more features, but a focused browser muter is better for one job: remove the audio track and hand the file back quickly.
