Zero quality loss
The video stream is copied bit-for-bit into a new container and the audio stream is dropped. Nothing is re-compressed, so the result is visually identical to your source.
Strip the sound from a video and keep the picture exactly as it was.
The video stream is copied bit-for-bit into a new container and the audio stream is dropped. Nothing is re-compressed, so the result is visually identical to your source.
Muting a video this way is an I/O operation, not a compute one. Even large files finish in seconds rather than minutes.
The result is written with the moov atom at the front, so it starts playing immediately when streamed rather than after a full download.
Most online 'mute video' tools re-encode the whole file, which costs time and quality for no reason. Removing an audio stream requires only rewriting the container.
The practical difference shows up on long files: a 45-minute 1080p video is muted in seconds by stream copy, and in many minutes by a full re-encode — with visibly softer output at the end of it.
No. The video stream is copied rather than re-encoded, so the picture is byte-identical to your source.
Not with this tool. Trim the section you want first, then remove the audio from that piece.
A muted upload cannot trigger an automated music-rights claim, and a silent file is slightly smaller. Volume control is a playback setting, not a property of the file.
Not from the muted file. If you want both, run the video-to-MP3 tool on the original first to keep a copy of the audio.
