1Upload the WMV videos whose soundtrack you want gone.
2Confirm that you want the audio track dropped entirely rather than turned down to silence.
3Run it — the track is removed at the container level and the picture is copied through untouched, so it finishes in seconds.
4Download the silent WMV file, which is also smaller than what you started with.
Mute WMV FAQ
How does Mute WMV remove the sound?
+
Concretely, the audio track is dropped from the container and the video stream is copied through untouched, so the operation is instant and the picture is bit-identical to the source rather than re-encoded. 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 through bit-identically and the job finishes in seconds regardless of how long the clip is.
Does the container format matter?
+
It does. WMV is Windows Media, tuned for low-bitrate playback in the Microsoft stack and increasingly unsupported elsewhere. That governs how the tracks are stored and therefore how cleanly one can be dropped.
Anything specific to WMV worth knowing?
+
Yes — WMV is tuned for low-bitrate Windows playback, so anything that raises quality is fighting the format rather than working with it. 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.
What can I upload to Mute WMV?
+
MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, M4V, MPEG and MPG. The container and codec are probed before anything runs, so a mixed batch is handled correctly per file rather than assumed to be uniform.
Is there a file size limit on Mute WMV?
+
Yes: free accounts process video up to 1 GiB per file, by far the most generous cap on the site; ffmpeg with x264, x265 and libvpx does the work, which is the same toolchain behind most desktop video software. Video is the one family where the cap is high enough that upload time, not the limit, is what you will actually notice.
Will Mute WMV lower the quality of my WMV videos?
+
It depends on whether the job needs a re-encode. Operations that only touch the container or the timeline are done as a stream copy and the picture is bit-identical to the source. Anything that has to redraw frames goes through x264/x265 at a quality level you set, where CRF 23 is visually transparent on most footage.
Can I run Mute WMV on several WMV videos at once?
+
Yes. Uploads queue in parallel, which matters more here than anywhere else because video jobs are minutes rather than seconds. Free accounts run one file at a time; a pass lifts that.
What happens to audio, subtitle and chapter tracks?
+
They are carried across. Multi-track audio, embedded subtitle tracks and chapter markers survive wherever the target container can represent them — that is the main thing that separates a proper job from a naive re-encode that silently keeps only track one.
Does Mute WMV cost anything?
+
No. Mute WMV is free without an account, and the output carries no watermark, no corner logo and no intro card. Uploaded video is deleted from the workers shortly after the job completes.
