ClipcoworkRemove 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.

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.

Questions
What counts as dead air in a video?
Dead air is any stretch where no one is talking — the pause before an answer, the breath between sentences, the seconds spent gathering a thought, the gap while you reset for the next take. Deadair mode targets exactly these silent stretches and leaves the talking alone.
Does it remove filler words like 'um' and 'uh'?
No. The pass detects speech versus silence, not specific words, so it can only cut the quiet. Your 'um's, restarts, and verbal tics are speech to the model and stay in — if you want those gone, you'll need a manual edit.
How is this different from generating clips?
Clips mode chops your video into short 9:16 verticals with captions for TikTok, Reels, and Shorts. Deadair mode keeps your one video whole and only strips the silence, returning a single tightened file in its original frame. Different mode, different output — pick it at upload.
How much shorter will my video get?
It depends entirely on how much you paused. Deadair only cuts silences longer than about a third of a second, so a tight, fast talker saves a little and a slow, rambly recording saves a lot. There is no fixed ratio — it removes the dead air that is actually there.
Can I remove silence from a podcast or webinar recording?
Yes — to remove silence from a podcast video, upload the video recording of the episode. Deadair mode works on video files (MP4, MOV, WebM), so you get a tighter cut of the real footage, not an audio-only export. Same for a recorded webinar or talk.
What format is the output?
One H.264 MP4 at your source resolution and aspect ratio, watermark-free. Horizontal recordings stay horizontal — deadair mode never crops to vertical or burns in captions. That reframing is clips mode’s job, not this one.
Does it work in languages other than English?
Yes, and identically in every one. The silence pass recognizes the sound of a human voice, not the words, so it trims dead air the same whether your footage is English, Spanish, Japanese, or Thai. The language menu only labels captions in clips mode — deadair mode ignores it entirely.
How much does it cost?
One credit per minute of source video, and your first video is free — no card. Paid plans add monthly credits and longer uploads that scale with your plan. If a job fails on our side, those credits are refunded automatically.
