Muting a video without touching the picture
A video file is a container that holds separate streams side by side: one for the picture and one or more for the sound. To make a silent version you don't have to change the picture at all. ClipLime simply leaves the audio stream out and copies the video stream into a fresh file, packet for packet.
Because the picture is never decoded and re-encoded, there is no quality loss of any kind. The codec, resolution, frame rate, bitrate and colors are exactly what you started with, and the job takes seconds instead of the minutes a full re-encode would need.
Good reasons to strip the sound
- Background loops for websites, kiosks and slides. Browsers autoplay videos that have no sound, so a silent file starts reliably.
- B-roll and stock footage that will get new music or a voice-over in your editor anyway.
- Private conversations, wind and traffic noise you'd rather not share along with the picture.
- Music you don't have rights to. A muted copy avoids claims on the soundtrack when you post the clip.
- Slightly smaller files. The silent copy is lighter by exactly the size of the audio track.
Want to keep the sound as well?
Removing the audio is permanent for the new file, but your original is never changed. If you need the sound on its own, extract the audio first and save it as an MP3, M4A or WAV. From there you can clean it up, cut it or level it in the audio editor.
If the real goal is a shorter clip rather than a silent one, the video trimmer cuts the start, end or a section from the middle.
Formats, phone videos and multiple tracks
The silent copy keeps the format of your file: MP4 stays MP4, MOV stays MOV, WebM stays WebM and MKV stays MKV. Files in other containers, such as MPEG-TS recordings, are saved as MP4. Need a different format afterwards? Run the result through the video converter.
Phone videos keep their rotation flag, so portrait footage stays upright. iPhone videos recorded in H.265 work too, even in browsers that can't play H.265, because the picture is copied rather than decoded.
Some files, especially MKVs, carry several audio tracks for different languages or commentary. All of them are removed, along with any subtitle tracks.
Limits worth knowing
- It removes the whole sound track. Silencing only a few seconds, or lowering the volume, needs an editor.
- It can't separate a voice from background music, it's all or nothing.
- The new file is put together in your browser's memory before you save it, so multi-gigabyte videos are more comfortable on a computer than on a phone.
