Mute Video FAQ
How does Mute Video remove the sound?
+
Concretely, the audio track is removed at the container level and the picture is copied without re-encoding, whatever the clip length. The result is the same picture with no audio track at all, rather than an audio track turned down to zero.
Is the video re-encoded when I mute it?
+
No. Removing a track is a container operation, so the video stream is copied bit-identically and is not re-encoded, however long the clip is.
Does the container format matter?
+
It does. this format is read and written by the same streaming pipeline as everything else we support. That governs how the tracks are stored and therefore how cleanly one can be dropped.
Anything specific to Video worth knowing?
+
Yes — the container and codec are probed before anything runs, so mixed uploads in one batch are handled per file. Relevant when the source has more than one audio track.
Can I remove just one audio track and keep another?
+
Muting removes the audio entirely. If a file carries several language tracks and you want to keep one, that is a track selection job rather than a mute, and it needs the conversion tools instead.
Should I mute or just silence the audio?
+
Mute. A silent track still occupies bitrate and still has to be decoded by the player; dropping it makes the file smaller and removes any chance of it being unmuted downstream.
Which video formats does Mute Video accept?
+
MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, M4V, MPEG and MPG. Each file is probed for its real container and codec before anything runs, so a mixed batch is handled correctly file by file.
Is there a file size limit on Mute Video?
+
Yes: free accounts process video up to 40 MB per file whichever container you brought; ffmpeg with x264, x265 and libvpx does the encoding. It is high enough that upload speed is usually the binding constraint rather than the cap itself.
Will Mute Video lower the quality of my videos?
+
Only when the picture itself has to change. Muting and trimming copy the video without re-encoding; resizing, flipping, speed changes and compression re-encode it.
Can I run Mute Video on several videos at once?
+
Yes, and it matters here more than anywhere else — video jobs run in minutes, so queueing the batch in parallel is the difference between one wait and several.
What happens to audio, subtitle and chapter tracks?
+
They are carried across wherever the target container can hold them, including multiple audio languages, embedded subtitles and chapter markers, rather than silently keeping only the first track of each.
Does Mute Video cost anything?
+
No. Mute Video is free without an account, and the output has no watermark, corner logo or intro card. The upload and the result are deleted automatically about 24 hours after the job, which leaves time to download the result.
