TEMPORARY MEDIA WORKSPACE / MUTE VIDEO
Mute Video
Remove every audio stream from a video and download a silent H.264 MP4 using a selected video quality profile.
Request-scoped temporary processingAdd one supported file up to 50 MB. Long or unusually large-frame media may be rejected before processing.No account required
Local API readinessMedia service ready
One bounded job runs per API worker by default.The processor required by this tool is available, and this worker can accept a temporary job.
1 file / 50 MB
Temporary server workspace
The selected bytes are sent only to the Nirmion media API for this request. Processing uses a private temporary workspace rather than permanent catalogue storage.
Request-scoped cleanup
Server-side source and result files are removed when the response stream closes. Re-downloads use the result Blob retained only in this browser tab.
Original stays unchanged
Nirmion writes a separately named result containing nirmion_tools and never overwrites the selected source file.
Know the product contract
What goes in, what changes, what comes back
Every media page documents the accepted source, the selected FFmpeg transformation, the output container, and the limits that can affect the job.
Prepare the source
Choose the correct source and confirm whether any dialogue, music, or ambient sound must be removed permanently from the result.
Apply one operation
FFmpeg maps the video stream only, excludes every audio stream, and encodes the frames as H.264 in a new MP4.
Receive a separate file
Play the full result with volume enabled to verify there is no audio stream and inspect video detail.
Plain-language method
How audio is removed from the video
All sound is intentionally absent, and the video receives one lossy encode. Muting cannot later restore the removed track from the result.
- 01Choose valid source media
Choose the correct source and confirm whether any dialogue, music, or ambient sound must be removed permanently from the result.
- 02Review the operation settings
Balanced is appropriate for most uses. High protects more detail; Smallest targets a lighter silent copy.
- 03Inspect and download the result
Play the full result with volume enabled to verify there is no audio stream and inspect video detail.
Useful when
Practical jobs this tool handles
- Prepare silent footage for a background banner.
- Remove private conversation from a shareable clip.
- Create a clean visual layer for later audio editing.
Before processing
Check the source and output choices first
- Confirm no source sound is needed in the result.
- Keep the original if audio may be needed later.
- Choose video quality based on visible detail.
- Test the result with player volume enabled.
Container and codec
Understand the output format
The output is an H.264 MP4 with no audio stream. It is not merely a zero-volume track.
Know the boundary
Muting removes all audio, not selected sounds
The tool cannot separate dialogue, music, people, or channels. Every audio stream is omitted from the result.
Quick answers
Questions before you process media
These answers describe the actual upload, FFmpeg processing, download, and temporary-retention contract.
Does this set volume to zero?
No. The output contains no audio stream at all.
Can I remove music but keep speech?
No. Selective source separation requires a different audio workflow.
Will video quality change?
The source is re-encoded according to the selected quality profile.
