Nodaro DocsRemove Audio
Strip the audio track from a video and keep a silent clip. The picture is copied without re-encoding, so nothing is lost and the node finishes almost at once.
The Remove Audio node removes the audio track from a video and outputs a silent clip. The picture is copied as it is, without re-encoding, so the node loses no quality and finishes almost instantly. It is the video half of splitting a clip, and Extract Audio is the audio half. The node has no settings.
When to use it
- Mute a video before you add sound effects or a different soundtrack.
- Make a clean, silent background clip for compositing.
- Drop an unwanted audio track without any loss of picture quality.
Quick start
Add the node
Press Tab on the canvas and choose Video › Sound for Video › Remove Audio.

Wire the clip into the Video input.

Click Run on the node. The silent clip appears on the node.

Remove Audio or another node?
Several nodes change the sound of a clip. Pick by what you want to end up with:
| You want | Use |
|---|---|
| A silent copy of the clip, to use on its own or in a composite | Remove Audio |
| A new soundtrack in place of the old one | Merge Video & Audio, with Original Audio set to Muted |
| New music or a voiceover on top of the clip's own sound | Merge Video & Audio, with Original Audio on Keep |
| Sound effects that follow the action on screen | Video SFX, which replaces the clip's own sound |
| The sound without the picture | Extract Audio |
Tips
- Replace a soundtrack. Wire the silent clip and your new sound into Merge Video & Audio. Merge Video & Audio can also mute the original sound itself, so removing it first is optional.
- Keep the sound instead. To keep the audio and drop the picture, use Extract Audio.
- Expect identical quality. The picture is not re-encoded, so the output has the same quality and codec as the input.
- Silent input stays silent. A video without sound comes back unchanged.
Frequently asked questions
Does Remove Audio reduce the quality of the video?
No. The picture is copied as it is, without re-encoding, so the quality and the codec of the output are identical to the input.
Do I need Remove Audio before Merge Video & Audio?
No. Merge Video & Audio can mute the video's original sound itself. Remove Audio is useful when you need the silent clip on its own.
What happens if the video has no sound?
The node returns the video unchanged, as a silent clip.
