Mute a Video
Type "mute the original audio" and Valmera silences it — no timeline, no track menus, no export settings. The original sound, background music, and any voiceover live on separate layers, so you can mute one, lower another to an exact level, and keep the rest. The export renders from your original upload at source quality.
It's the fastest kind of edit to describe — and because Valmera is an agentic editor, describing it is all you do.

- 1Upload your videoDrag in any video up to 2GB (up to 3 hours). Valmera analyzes it once with visible progress, then keeps the audio on layers you can control independently.
- 2Type the requestType something like "mute the original audio completely", "lower the original audio to 20%", or "mute my talking but keep the music we added". The agent applies it to exactly the layer you named.
- 3Preview, refine, exportCheck the preview — silence is easy to verify — then adjust or add replacement audio with a follow-up message. Export a full-quality H.264 MP4 rendered from your original upload, with only a small corner mark on the free plan.
The upload is analyzed once with visible progress; after that, muting or re-leveling a layer is a single chat message.
Mute the Original Audio in One Request
Wind noise, an awkward conversation in the background, a screen recording narrated by your fan hum — sometimes the right amount of original audio is none. In Valmera, muting the original track is a first-class edit: it goes fully to silence while the picture stays untouched, and every other layer you've added — music, voiceover, sound effects — keeps playing exactly as mixed.
Because the agent's replies are server-verified by the honesty layer, "the original audio is muted" is a checked fact about the actual edit — not a hopeful summary.
Lower the Volume Instead — Per-Layer Control
Muting is a special case of a more useful capability: independent gain on every layer. "Original audio at 20%", "music at half volume", "voiceover full" — each is a one-sentence mix decision, and they compose. Keep a whisper of location sound under a new music bed, or set levels to taste when the automatic behavior isn't what the moment needs.
The automatic behavior is good, though: music ducks smoothly under speech via sidechain compression, and a one-request master targets −14 LUFS / −1.5 dBTP — the loudness platforms expect. The whole audio stack is documented in the audio and music docs.
Swap the Sound: Music or Voiceover Instead
Most people don't want a silent video — they want different sound. After the mute, one message rebuilds the soundtrack: add music from the 24-track royalty-free CC0 library (8 moods) or your own uploads, lay a voiceover on top and let everything duck under it automatically, or punctuate the cut with sound effects — 18 built-in one-shots plus describe-any-sound generation.
Muting vs. Removing Silence
Two different jobs that get confused. Muting keeps every frame and silences the sound — the video is just as long, only quiet. Silence removal is the opposite: it finds the dead air where nobody is talking and cuts those stretches out, making the video shorter and tighter. If your goal is pacing rather than quiet, you want the silence remover — same editor, different sentence.
Honest Limits
Muting works on layers, and your uploaded video's sound arrives as one layer. That means Valmera can't remove the speech but keep music that's baked into the same original track — no honest tool can unmix a single baked track. What it can do is automate the original audio's level over a specific time range — including all the way down to silence — so one regrettable sentence can go quiet without losing the picture. Cutting the moment out is the other route: cuts snap to word boundaries and any removed range can be restored later.
And there's no denoise or "studio sound" processing — if the original audio is worth keeping but noisy, lowering it under music is usually the honest best move.
More Than a Mute Tool
The mute is usually step one of a bigger clean-up. The same chat cuts silences and filler words, styles word-accurate captions, reframes for 9:16, adds transitions and zooms, and grades the color — browse all the AI video editing tools to see what one more sentence can do.
