Remove dead air from video, keep every word
A video silence remover for talking-head footage: one pass finds your speech and drops the dead air around it. You get a tighter video, not a project file.
Your first video is free. No credit card.
Dead air is the drag on every long recording — the pause before an answer, the breath between sentences, the seconds spent finding the next thought. Deadair mode has one job: remove dead air from video. It makes one pass to remove silence from video — every stretch the model hears as quiet, not speech — and returns a single tightened file in its original frame. Silero voice-activity detection does the marking; it cuts the quiet, not your delivery.
Dead air, gone. Words, intact.
Voice detection, not a volume gate
Silero VAD is a neural model trained to recognize the sound of a human voice, not raw loudness. It holds through soft talkers, accents, and quiet rooms where a plain decibel threshold would cut you off mid-word.
It cuts silence, not filler
Deadair mode removes the gaps — the pauses, the breaths, the dead time between takes. It has no idea what you said, so it never touches an 'um,' a restart, or your phrasing. Words in, words out; only the quiet leaves.
One tightened video, original frame
You get a single cleaned MP4 at your source resolution and aspect ratio — no forced 9:16 crop, no burned-in captions. Horizontal stays horizontal, right for YouTube, course lessons, and webinar replays.
Cuts that keep their timing
Every kept segment carries about 150 milliseconds of padding on each side, and any pause shorter than roughly a third of a second stays in. Long gaps disappear; the rhythm of your delivery survives, so nothing lands like a jump cut.
Four steps, one clean cut
Upload the video
Send your MP4, MOV, or WebM straight to secured, account-scoped storage. For a podcast or webinar, upload the video recording — deadair mode works on video files, not audio-only tracks.
Choose deadair mode
Pick deadair instead of clips at upload. This is the silence pass: it tightens the entire recording rather than slicing it into shorts, and it runs on the whole file no matter how long it is.
Silero VAD trims the silence
The model scans your audio, marks where speech happens, and rebuilds the video from those segments with the dead air removed. It keeps breathing room around each cut so the result plays as continuous talk.
Download the tightened video

Tighten your next recording
Cut dead air from a recording, tighten an interview, clean up a webinar replay — deadair mode returns a finished cut, not a timeline to edit. Upload a talking-head video and let Silero VAD make the pass. Your first video is free, no credit card.
